Dojo 1.x to 2.0 migration guide¶
Currently, many parts of Dojo 2.0 are under development. As with any major software that is under-development, it is hard to predict that the final solution will look like. These notes provide guidence though on how to try to “future proof” your application to make it easier to transistion to Dojo 2.0 when it release.
Since Dojo 1.X is backwards compatible with previous Dojo 1.x releases, none of these changes are necessary until Dojo 2.0, but refactoring your code earlier will not only make future porting easier, but also can deliver performance and code maintenance benefits early.
AMD¶
Dojo has been upgraded to use the Asynronous Module Definition (AMD) standard for all of its modules. This changes the way you load, access, and define modules.
Loading dojo.js¶
Dojo is loaded basically in the same way as before, except that in the <script>
tag the djConfig
attribute has
been renamed to data-dojo-config
.
To get the 2.0-like behavior in 1.7, you should set async: true
.
<script src="dojo/dojo.js" data-dojo-config="async: true"></script>
If configuration options are specified outside of the <script>
tag (rather than as a data-dojo-config
attribute), instead of djConfig
you should set dojoConfig
:
var dojoConfig = { async: true }
Loading Modules¶
The syntax for loading modules has been changed from a series of dojo.require()
calls like:
dojo.require("dijit.form.Button");
dojo.require("dojox.layout.ContentPane");
...
// CODE HERE
into a single require statement:
require(["dijit/form/Button", "dojox/layout/ContentPane", ...], function(Button, ContentPane, ...){
// CODE HERE
});
Notice how the dots (e.g. dijit.form.Button
) have been changed to slashes (e.g. dijit/form/Button
). This is
dot notation represented a global scope object where as the slash notation represent a Module ID (MID). While these
are similiar in naming, there are actually wholly different concepts.
Also, be careful to never load a module using a <script>
tag. This will not work; it causes “multiply defined”
errors from the loader.
Accessing Modules¶
Each module you load is mapped to a function parameter:
require(["dijit/_base/Color", "dojox/layout/ContentPane"], function(Color, ContentPane){
Color.fromRgb(...)
});
That function parameter is the way that you access methods or the class defined in that module. You should no longer
access any functionality through global variables like dojo
, dijit
, or dojox
.
One implication of this change is that every module you are (directly) using must be put into your dependency list.
That includes any functionality previously loaded by dojo.js
. The modules that formerly composed dojo.js
(modules in dojo/_base
) have been replaced with smaller, more specific modules in the top level dojo
directory.
Also, note that some method names have been shortened to avoid redundancy. For example, the previous
dojo.colorFromRgb()
is now accessed as Color.fromRgb()
, rather than Color.colorFromRgb()
.
Defining Modules¶
The syntax for defining a module is similar to require()
. In other words, it has been changed from:
dojo.provide("acme.Dialog");
dojo.require("dijit._Widget");
dojo.require("dojo.date");
//CODE HERE
into:
define(["dijit/_Widget", "dojo/date"], function(_Widget, date){ ....
// CODE HERE
return MyWidget;
});
Notice that the module (a.k.a. file) itself is returning a value. That is the way other modules access your module, as explained in the section above.
Also, notice how the module name previously listed in the dojo.provide()
call (acme.Dialog
in the example
above) is not listed anymore. The file name itself suffices.
I18N¶
dojo.requireLocalization()
has been replaced by the dojo/i18n! loader plugin:
Old syntax:
dojo.require("dojo.i18n");
dojo.requireLocalization("dijit.form", "validate");
var validate = dojo.i18n.getLocalization("dijit.form", "validate");
console.log(validate.invalidMessage);
New syntax:
require(["dojo/i18n!dijit/form/nls/validate"], function(i18n){
console.log(i18n.invalidMessage);
});
Loading Text Resources and Widget Templates¶
Use the dojo/text! plugin instead.
Old syntax:
var text = dojo.cache("my.module", "template.html");
// ...
New syntax:
require("dojo/text!my/module/template.html", function(text){
//...
});
URLs¶
Most of the time you use the dojo/text!
plugin to load text from a specific URL, but if you need an actual URL in
your classes you should use require.toUrl()
.
See require.toUrl() and context sensitive require for details.
Quick Reference¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.provide(“foo/bar”); dojo.require(“a/b”); ... | define([“a/b”], function(b){ ... }); | |
dojo.require(a.b); a.b.foo(); | require([“a/b”], function(b){ b.foo(); } | |
djConfig | data-dojo-config | |
dojo._Url | require.toUrl() | |
dojo.moduleUrl(“dijit”, “foo.template.html”) | require | require.toUrl(“dijit/foo/template.html”) |
dojo.requireLocalization() | dojo/i18n! | see I18N section above |
dojo.getLocalization() | dojo/i18n! | see I18N section above |
dojo.cache(“my.module”, “template.html”) | dojo/text! | require(“dojo/text!my/module/template.html”, function(text){ ... |
Dojo Core¶
Basic functions¶
Testing object types¶
2.0 will remove the isXXX()
functions defined in dojo/_base/lang
. In most cases they can be easily replaced
with simple native tests:
1.x | 2.0 |
---|---|
dojo.isString(v) |
typeof v == "string" |
dojo.isArray(v) |
v instanceof Array |
dojo.isFunction(v) |
typeof v == "function" |
dojo.isArrayLike(v) |
"length" in v , etc. (but see note below) |
Notes:
- On some browsers
"length" in v
will return true for strings and functions, so if you are trying to differentiate between strings and arrays of strings, use thetypeof v == "string"
test instead, and if you are trying to differentiate between functions and arrays of functions, use thetypeof v == "function"
test instead. It will also returntrue
for built-in constructors (Number
,String
, etc.) which havelength
. typeof value == "function"
won’t match IE’s hosted functions (likealert
).v instanceof Array
won’t work ifv
was created in a different frame.
dojo/_base/lang¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.extend | dojo/_base/lang | lang.extend |
dojo._hitchArgs | dojo/_base/lang | lang._hitchArgs |
dojo.hitch | dojo/_base/lang | lang.hitch |
dojo.delegate | dojo/_base/lang | lang.delegate |
dojo._toArray | dojo/_base/lang | lang._toArray |
dojo.partial | dojo/_base/lang | lang.partial |
dojo.clone | dojo/_base/lang | lang.clone |
dojo.trim | dojo/_base/lang | lang.trim |
dojo.replace | dojo/_base/lang | lang.replace |
dojo.mixin | dojo/_base/lang | lang.mixin |
dojo._mixin | dojo/_base/lang | lang._mixin |
dojo.exists | dojo/_base/lang | lang.exists |
dojo.getObject | dojo/_base/lang | lang.getObject |
dojo.setObject | dojo/_base/lang | lang.setObject |
dojo/_base/kernel¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.deprecated | dojo/_base/kernel | kernel.deprecated |
dojo.experimental | dojo/_base/kernel | kernel.experimental |
dojo.version | dojo/_base/kernel | kernel.version |
dojo.eval | dojo/json | native eval() or json.parse() for json |
dojo/_base/array¶
To be determined - Dojo 2.0 may have dojo/array
, or dojo/each
, or just shim Array
prototype on IE to match behavior of modern browsers.
In 1.7 and later, use “dojo/_base/array” module to get forEach()
, map()
, etc:
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.forEach | dojo/_base/array | array.forEach |
dojo.map | dojo/_base/array | array.map |
dojo.filter | dojo/_base/array | array.filter |
dojo.every | dojo/_base/array | array.every |
dojo.some | dojo/_base/array | array.some |
dojo.indexOf | dojo/_base/array | array.indexOf |
Browser/Device Sniffing¶
If your code uses browser sniffing, you should load dojo/sniff or dojox/mobile/sniff. Both these modules leverage the dojo/has API for feature detection.
For example, old code like:
if(dojo.isIE < 6){
// ...
}
should be changed to:
require(["dojo/has", "dojo/_base/sniff"], function(has){
if(has("ie") < 6){
// ...
}
});
Load and Unload Handlers¶
Loading and unloading have been moved to dojo/ready
and dojo/_base/unload
:
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.addOnLoad(f) | dojo/ready | ready(f) |
dojo.ready(f) | dojo/ready | ready(f) |
dojo.addOnUnload | dojo/_base/unload | unload.addOnUnload |
dojo.addOnWindowUnload | dojo/_base/unload | unload.addOnWindowUnload |
Events¶
dojo.connect()
/ dojo.disconnect()
for monitoring DOMNode events have been replaced by the on()
method
returned from the dojo/on module. (For dojo.connect()
usage as advice on plain JavaScript
functions/methods, see the Advice section below)
Old code like:
var handle = dojo.connect(node, "onclick", callback);
// ...
dojo.disconnect(handle);
should be converted to:
require(["dojo/on"], function(on){
var handle = on(node, "click", callback);
// ...
handle.remove();
});
Note that:
- the
on
prefix was dropped, andonclick
becameclick
- the “handle” has a remove() method, rather than there being a function like dojo.disconnect()
The NodeList objects returned from dojo/query
also works with an .on()
method rather than a .connect()
method.
Old code like:
dojo.query("li").connect("onclick", callback);
should be converted to:
require(["dojo/query"], function(query){
query("li").on("click", callback);
});
mouseenter/mouseleave¶
Dojo supports onmouseenter
/onmouseleave
synthetically for browsers that do not support those events natively.
In 1.x these events were specified as strings, just like native events:
dojo.connect(node, "onmouseenter", callback);
Now they are specified by event objects defined in dojo/mouse
, which must be explicitly loaded, and used like this:
require(["dojo/on", "dojo/mouse"], function(on, mouse){
on(node, mouse.enter, callback);
});
Similarly, "onmouseleave"
has become mouse.leave
.
Mouse Buttons¶
dojo.mouseButtons
has been replaced by the dojo/mouse
module, which must be explicitly loaded.
Code like:
dojo.connect(node, "onmousedown", function(evt){
if(dojo.mouseButtons.isLeft(evt){ ... }
});
should be converted to:
require(["dojo/on", "dojo/mouse"], function(on, mouse){
on(node, "mousedown", function(evt){
if(mouse.isLeft(evt)){ ... }
});
});
Keys¶
The symbolic names for keys have been put into the dojo/keys module, which must be explicitly loaded and can be accessed like this:
require(["dojo/on", "dojo/keys"], function(on, keys){
on(node, "keydown", function(evt){
if(evt.keyCode == keys.F10){ ... }
});
});
onkeypress¶
The Dojo onkeypress
normalization to Firefox behavior has been desupported. For portable applications, you must use keypress
for monitoring printable characters (e.g. A-Z, 1-9):
on(node, "keypress", function(evt){
if(e.charCode <= 32){
// Avoid duplicate events on firefox (this is an arrow key etc. that will be handled by keydown handler)
return;
}
var char = String.fromCharCode(evt.charCode);
// ...
});
and keydown for non-printable characters (e.g. arrow keys):
on(node, "keydown", function(evt){
switch(evt.keyCode){
case keys.UP_ARROW:
// ...
break;
}
});
Note that the normalization of evt.charOrCode
is also gone, so use evt.charCode
for keypress events, or
evt.keyCode
for keydown events.
Event Delegation¶
The dojo.behavior
and dojox.NodeList.delegate
modules have been replaced by functionality built-in to
dojo/on
.
Old code:
var myBehavior = {
"#mylist li:click" : {
onclick: onListItemClickHandler
}
};
dojo.behavior.add(myBehavior);
dojo.behavior.apply();
New code:
require(["dojo/on", "dojo/query", "dojo/_base/window"], function(on, query, win){
on(win.doc(), "#mylist li:click", onListItemClickHandler);
});
connectPublisher()¶
dojo.connectPublisher()
was an automation of this common form:
dojo.connect(myObject, "myEvent", function(){
dojo.publish("/some/topic/name", arguments);
});
Which became:
dojo.connectPublisher("/some/topic/name", myObject, "myEvent");
But in 2.0 users should use the following for connecting to DOM events:
require(["dojo/on", "dojo/topic"], function(on, topic){
on(myNode, "click", function(){
topic.publish("/some/topic/name", arg1, arg2, arg3);
});
});
Or this for after-advice on arbitrary methods of arbitrary objects:
require(["dojo/aspect", "dojo/topic"], function(aspect, topic){
aspect.after(myObj, "myFunc", function(){
topic.publish("/some/topic/name", arg1, arg2, arg3);
});
});
Quick Reference¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.connect(node,"onclick",cb) | dojo/on | on(node,"click",cb) (note that "on" prefix removed) |
dojo.connect(node,"onmouseenter",cb) | dojo/on,dojo/mouse | on(node,mouse.enter,cb) |
dojo.connect(node,"onmouseleave",cb) | dojo/on,dojo/mouse | on(node,mouse.leave,cb) |
dojo.connect(node,"onkeypress",cb) | dojo/on | on(node,"keypress",cb) for printable or on(node,"keydown",cb) for arrows etc. |
dojo.disconnect(handle) | handle.remove() | |
dojo.connectPublisher | see above | |
dojo.fixEvent | dojo/_base/event | event.fix |
dojo.stopEvent | dojo/_base/event | event.stop |
dojo.mouseButtons.is***() | dojo/mouse | mouse.is***() |
dojo.isCopyKey | ? | ? |
Advice¶
dojo.connect()
could be used to perform after advice (based on the conecpts of Aspect Oriented Programming) on a
method. In 2.0 that has been replaced by the dojo/aspect
package.
Old code:
var handle = dojo.connect(myInstance, "execute", callback);
// ...
dojo.disconnect(handle);
is changed to:
require(["dojo/aspect"], function(aspect){
var handle = aspect.after(myInstance, "execute", callback);
/ ...
handle.remove();
});
Note that callback()
should not return a value, because if it did the returned value would be reported as the
value that myInstance.execute()
appeared to return, which is not what dojo.connect()
did.
Quick Reference¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.connect(obj,method,cb) | dojo/aspect | aspect.after(obj,method,cb) |
dojo.disconnect(handle) | handle.remove(); |
Publish and subscribe¶
dojo.publish()
/dojo.subscribe()
/dojo.unsubscribe()
have been replaced by the dojo/topic
module.
Old code:
var handle = dojo.subscribe("some/topic", context, callback);
// ...
dojo.unsubscribe(handle);
is changed to:
require(["dojo/topic"], function(topic){
var handle = topic.subscribe("some/topic", listener)
// ...
handle.remove();
});
And publishing code is changed from:
dojo.publish("some/topic", [1, 2, 3]);
to:
require(["dojo/topic"], function(topic){
topic.publish("some/topic", 1, 2, 3);
});
Note that no array brackets are used anymore.
Quick Reference¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.publish("/foo", [1,2,3]) | dojo/topic | topic.publish("/foo", 1, 2, 3) |
dojo.subscribe("/foo", callback) | dojo/topic | topic.subscribe("/foo", callback) |
dojo.unsubscribe(handle) | handle.remove() |
DOM Manipulation¶
The Dojo DOM related functions previously available as part of dojo/dojo.js
are now in a number of modules which must each be explicitly loaded. These modules are:
- dojo/dom: general functions
- dojo/dom-attr: setting node attributes
- dojo/dom-class: adding and removing classes
- dojo/dom-construct: creating and destroying nodes
- dojo/dom-form: form related
- dojo/io-query: query conversion fucntions
- dojo/dom-geometry: node sizing
- dojo/dom-prop: setting node properties
- dojo/dom-style: setting/getting style for a node
Note in particular that node attribute setting and property setting has been split up. dojo/dom-attr
will
eventually be deprecated in lieu of dojo/dom-prop
.
Note also that combination accessor functions like dojo.marginBox()
, dojo.contentBox()
, and dojo.style()
have been split into separate setter and getter methods.

dojo.doc | dojo/_base/window | window.doc |
dojo.body | dojo/_base/window | window.body |
dojo.setContext | dojo/_base/window | window.setContext |
dojo.withGlobal | dojo/_base/window | window.withGlobal |
dojo.withDoc | dojo/_base/window | window.withDoc |
JSON¶
The JSON methods are available from the dojo/json package, which must be loaded explicitly.
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo.fromJson | dojo/json | json.parse |
dojo.toJson | dojo/json | json.stringify |
Note that the new methods only accept true JSON, not arbitrary JavaScript. Even the keys in a hash must be quoted
Valid:
{ "foo": 1, "bar": 2 }
Invalid:
{ foo: 1, bar: 2 }
TODO: IIRC single quotes are also invalid.
Parser¶
Running the Parser¶
The parser is in the dojo/parser module, invoked like:
require(["dojo/parser"], function(parser){
parser.parse();
});
Even if you are parsing declaratively via the parseOnLoad: true
dojoConfig
setting, you need to explicitly
require the parser.
data-dojo-type and data-dojo-props¶
dojoType
has been renamed to data-dojo-type
, and a new data-dojo-props
parameter has been created to
specify non-native attributes in a way that doesn't violate HTML5 validation.
Old code:
<button dojoType="dijit.form.Button" tabIndex=2
iconClass="checkmark">OK</button>
New code:
<button data-dojo-type="dijit/form/Button" tabIndex=2
data-dojo-props="iconClass: 'checkmark'">OK</button>
data-dojo-props
is a hash that contains name value pairs, for example: data-dojo-props=" name: 'hi', size: 123"
.
Connecting to Widget Events¶
Previously you could use <script type="dojo/connect">
to monitor widget events and connect to methods:
<button data-dojo-type="dijit.form.Button">
<span>Click Me!</span>
<script type="dojo/connect" event="onclick" args="e">
// ...
</script>
</button>
Now the following is used: <script type="dojo/on">
for events like click, <script type="dojo/watch">
to monitor
changes to a widget's attribute:
<button data-dojo-type="dijit/form/Button">Click Me!
<script type="dojo/on" data-dojo-event="click" data-dojo-args="e">
// ...
</script>
</button>
<div data-dojo-type="dijit/form/TextBox" id="textBox1"
data-dojo-props="value: 'Old Value'">
<script type="dojo/watch" data-dojo-prop="value" data-dojo-args="prop,oldValue,newValue">
console.log("Prop '"+prop+"' was '"+oldValue+"' and is now '"+newValue+"'");
</script>
</div>
jsId¶
The jsId attribute has been removed. Replace all jsId references with data-dojo-id, the behavior is identical.
<div data-dojo-id="bar" data-dojo-type="some/Thinger">I am exported to window.bar by reference</div>
Query¶
dojo/query
is a new module similar to the old dojo.query()
function. In general you can use it like
dojo.query()
, so old code like:
dojo.query("li").connect("onclick", callback)
can been replaced by:
require(["dojo/query"], function(query){
query("li").on("click", callback);
});
Points of caution:
1. As before, you need to require certain NodeList extension modules to get added methods on the NodeList return from
query()
. The difference is that now the NodeList DOM functions also need to be explicitly loaded. So you need to do:require(["dojo/query", "dojo/NodeList-dom"], function(query){ query("li").style("display", "none"); });2.
query()
can load various selector engines. By default it uses thedojo/selector/light
engine. If you have complicated queries you need to switch it to use a more powerful engine. See dojo/query for details.There are a couple of ways to set the selector engine. First, we can define the selector engine as part of the dojo configuration for the whole page:
<script data-dojo-config="selectorEngine='css2.1'" src="dojo/dojo.js"></script>You can also specify the selector engine level you are dependent on for each of your modules. This is done by indicating the CSS selector engine level after
!
in thedojo/query
module id. For example, if your module needed to do a CSS3 level query, you could write:define(["dojo/query!css3"], function(query){ query(".someClass:last-child").style("color", "red"); });
Stores¶
The dojo.data API stores have been replaced with the new dojo/store API.
dojo.data | dojo/store |
---|---|
store.getValue(item, "foo") | item.foo |
store.getLabel(item) | item.label |
store.getItemByIdentitfier(id) | store.byId(id) returns Deferred |
store.fetch(...) | store.query() returns Deferred |
In order to aid transistion, there are two modules that are available:
- dojo/store/DataStore - Can convert a legacy
dojo.data
API store and make it appear to be a nativedojo/store
. - dojo.data.ObjectStore - Wraps a
dojo/store
API store and makes it appear to be a legacydojo.data
store.
Many Dijits are now directly dojo/store
aware, including: dijit/form/ComboBox,
dijit/form/FilteringSelect, and dijit/Tree.
Declaring Classes¶
dojo.declare()
has been migrated to dojo/_base/declare. There may be further changes
for Dojo 2.0, for example replacing it by ComposeJS, or may have more modest changes. For now, for classes you don't
need in the global scope, you should declare them as baseless. Something like this:
dojo.provide("package.myClass");
dojo.require("dijit._Widget");
dojo.declare("package.myWidget", [dijit._Widget], {
// myWidget Class declaration
});
Should change to something like this:
define(["dojo/_base/declare", "dijit/_WidgetBase"],
function(declare, _WidgetBase){
return declare([_WidgetBase], {
// myWidget Class declaration
});
});
Notice the omission of the first argument in the declare()
. This means that nothing will be set in the global
scope. Also, the mixin array uses the return values of the define requirement array, instead of the legacy class
names. This means that your custom class will only be available within the closure scope of a require()
or
define()
that has required it in.
This does mean your module can only return a single public class, which is more consistent with the concepts of AMD and baseless anyways, but if you need to create a private class that isn't referenced outside the current module, you can simply declare it as a variable. For example:
define(["dojo/_base/declare", "dijit/_WidgetBase"],
function(declare, _WidgetBase){
var _myMixin = declare(null, {
// _myMixin Class private declaration
});
return declare([_WidgetBase, _myMixin], {
// myWidget Class
});
});
FX¶
The base FX features of dojo/dojo.js
have been moved to dojo/_base/fx and the additional features of the dojo.fx
module are now in dojo/fx.
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|
dojo._Line | dojo/_base/fx | baseFx._Line |
dojo.Animation | dojo/_base/fx | baseFx.Animation |
dojo._fade | dojo/_base/fx | baseFx._fade |
dojo.fadeIn | dojo/_base/fx | baseFx.fadeIn |
dojo.fadeOut | dojo/_base/fx | baseFx.fadeOut |
dojo._defaultEasing | dojo/_base/fx | baseFx._defaultEasing |
dojo.animateProperty | dojo/_base/fx | baseFx.animateProperty |
dojo.anim | dojo/_base/fx | baseFx.anim |
Miscellaneous¶
1.x syntax | 2.0 module | 2.0 syntax |
---|---|---|

Mapping table for dijit¶
This is a quick lookup table for methods, attributes, etc. in 1.x mapped to their equivalent method in that module in 2.0. Note that many methods that were previously included automatically now need to be explicitly loaded.
The sections underneath this give more detail on conversions.

set(), get()¶
Old widget methods to set and get parameter values, such as:
myEditor.getValue()
myTextBox.attr("value")
myForm.setValue(...);
have been replaced by the standard set()
and get()
methods:
myEditor.get("value")
myTextBox.get("value")
myForm.set("value", ...);
watch(), on()¶
Old widget methods to monitor widget events or changes in widget parameters have been consolidated to use on()
and
watch()
:
Old code:
dojo.connect(myForm, "onValidStateChange", function(){ ... });
dojo.connect(myButton, "onClick", clickCallback);
New code:
myForm.watch("valid", function(name, oldVal, newVal){
console.log(myForm.id + ": " + name + " changed from " +
oldVal + " to " + newVal);
});
myButton.on("click", clickCallback);
Templated Widgets¶
The dijit/_Templated
mixin has been split into dijit/_TemplatedMixin
and dijit/_WidgetsInTemplateMixin
. In
addition, dojoAttachPoint
and dojoAttachEvent
have been changed to the HTML5 valid data-dojo-attach-point
and data-dojo-attach-event
.
For example, old code like:
dojo.require("dojo.declare");
dojo.require("dijit._Widget");
dojo.require("dijit._Templated");
dojo.declare("SimpleTemplate", [dijit._Widget, dijit._Templated], {
templateString: "<button><span dojoAttachPoint="label"></span></button>"
});
will change to:
require(["dojo/declare", "dijit/_WidgetBase", "dijit/_TemplatedMixin"],
function(declare, _WidgetBase, _TemplatedMixin){
declare("SimpleTemplate", [_WidgetBase, _TemplatedMixin], {
templateString: "<button><span data-dojo-attach-point="label"></span></button>"
});
});
If the above example had widgets in the templates, it would also mixin dijit/_WidgetsInTemplateMixin
.
To specify a template from a file, templatePath
is no longer supported, and dojo.cache()
shouldn't be used
either.
Old code:
templatePath: dojo.moduleUrl("templates", "myTemplate.html")
New code:
define([..., "dojo/text!./templates/myTemplate.html",
function(..., myTemplate){
...
templateString: myTemplate
The other change to widgets is that the waiRole
and waiState
parameters are no longer supported, since it's
now easy to use role and state directly.
For instance. Replace:
<span waiRole="treeitem" waiState="selected-false,haspopup-true"></span>
With:
<span role="treeitem" aria-selected="false" aria-haspopup="true"></span>
attributeMap¶
attributeMap in 1.x was a hash mapping widget attributes to DOM nodes. For example:
attributeMap: {
"index": "focusNode",
"style": "domNode"
}
Currently, this is achieved by making separate _setXXXAttr
attribute for each attribute to map. Originally
_setXXXAttr
was a function to set a widget attribute. It can still be a function, but now it can also be an
object like one of the values from attributeMap
.
The code above would be expressed as:
_setTabIndexAttr: "focusNode",
_setStyleAttr: "domNode"
Base Functionality¶
The methods previously loaded into dijit
by default now must be explicitly loaded from various modules.
TODO: list stuff in dijit/registry
, dijit/a11y
.
dijit/focus, dijit/place, and dijit/popup¶
The focus, place, and popup modules in dijit/_base
have been promoted to root of dijit
, so they need included
explicitly by applications that don't want to include all of dijit/_base
.
There are a few API changes in the top level modules compared to the ones in dijit/_base
(although for backwards
compatibility the modules in dijit/_base
maintain their old API):
Popup.around()
(analogous todijit.popup.placeAroundElement()
) takes a position parameter like["before", "after"]
rather than a set of tuples like{BL: "TL", ...}
. In other words,Popup.around()
replacesdijit.popup.placeAroundElement()
but instead ofdijit.getPopupAroundAlignment(xyz)
, just pass inxzy
directly.dijit/focus
doesn't include the selection related code, just focus related codedijit/focus
provides.watch()
and.on()
methods to monitor the focused node and active widgets, rather than publishing topicsfocusNode
,widgetBlur
, andwidgetFocus
.- Some methods in
dijit/_base/popup
used to take DOMNodes or widgets as a parameter; now they just take a widget
Also note that the new dijit/popup module is only available through the new AMD API, e.g.:
require(["dijit/popup"], function(popup){ popup.open(...); });
Some functions from dijit
have been moved to dojo
core.
dojo/uacss
will add classes to the<html>
node likedj_ie
, representing the browser, browser version, box model, etc. Formerlydojo.require("dijit.sniff")
.getBox()
fromdojo/window
gets the viewport size. Formerlydijit.getViewport()
.get()
fromdojo/window
converts a document to the corresponding window. Formerlydijit.getDocumentWindow()
scrollIntoView()
fromdojo/window
scrolls a node into view, similar tonode.scrollIntoView()
but working around browser quirks. Formerlydijit.scrollIntoView()
.
SplitContainer, LayoutContainer¶
Use BorderContainer instead. (TODO: examples)
Miscellaneous changes¶
_Widget --> _WidgetBase
DojoX¶
The dojox
namespace will be removed in Dojo 2.0. Some of the mature sub-packages will like migrate into Dojo Core
or into Dijit. The remaining code will be "spun off" into seperate packages that will be available via package
management tools and a repository of packages.
In order to ensure your code is easily migrateable, refactoring it to fully leverage AMD and not relay upon the
dojox
global variable is critically important.
