dojo/fx/Toggler is a helper class for wrapping a DOM node with ‘FX’ to use when showing and hiding that node. By default it uses the dojo/_base/fx::fadeIn() for showing and dojo/_base/fx::fadeOut() for hiding of a node. The Toggler is set up by passing in an JavaScript object of parameters that define the node, the animation functions to use, and the duration for the show and hide operations.
Usage¶
Usage is creating a new instance of the class, passing at least the DOMNode that the instance should relate to:
require(["dojo/fx/Toggler"], function(Toggler),{
// Create a new Toggler with default options
var toggler = new Togger({
node: "someId"
});
// Hide the node
toggler.hide();
// Show the node
toggler.show();
});
The constructor takes a hash of parameters:
| Parameter | Type | Description |
|---|---|---|
| node | DOMNode|String | The DOMNode or ID of the node that the Toggler applies to |
| showDuration | Integer? | Optional How long, in milliseconds, the show function is applied for. Defaults to
200. |
| showFunc | Function? | Optional The function that is applied on .show(). Defaults to
dojo/_base/fx::fadeIn() |
| hideDuration | Integer? | Optional How long, in milliseconds, the hide function is applied for. Default to 200. |
| hideFuc | Function? | Optional The function that is applied on .hide(). Defaults to
dojo/_base/fx::fadeOut() |
show()¶
This method plays the show animation and takes one optional argument:
| Argument | Type | Description |
|---|---|---|
| delay | Integer? | Optional The amount of time, in milliseconds, that the animation should be delayed before starting.
Defaults to 0. |
.show() returns an instance of dojo/_base/fx::Animation.
hide()¶
This method plays the hide animation and takes one optional argument:
| Argument | Type | Description |
|---|---|---|
| delay | Integer? | Optional The amount of time, in milliseconds, that the animation should be delayed before starting.
Defaults to 0. |
.hide() returns an instance of dojo/_base/fx::Animation.
Examples¶
Example 1: Toggle a DOM node (with defaults)¶
require(["dojo/fx/Toggler", "dojo/dom", "dojo/on", "dojo/domReady!"],
function(Toggler, dom, on){
var toggler = new Toggler({
node: "basicNode"
});
on(dom.byId("hideButton"), "click", function(e){
toggler.hide();
});
on(dom.byId("showButton"), "click", function(e){
toggler.show();
});
});
<button type="button" id="hideButton">Hide the node! </button>
<button type="button" id="showButton">Show the node! </button>
<div id="basicNode" style="width: 200px; background-color: red;">
<b>This is a container of random content to toggle!</b>
</div>
Example 2: Toggle a DOM node with custom durations¶
This example has a slow fade out and a slowish fade in.
require(["dojo/fx/Toggler", "dojo/dom", "dojo/on", "dojo/domReady!"],
function(Toggler, dom, on){
var toggler = new Toggler({
node: "basicNode",
showDuration: 3000,
hideDuration: 5000
});
on(dom.byId("hideButton"), "click", function(e){
toggler.hide();
});
on(dom.byId("showButton"), "click", function(e){
toggler.show();
});
});
<button type="button" id="hideButton">Hide the node! </button>
<button type="button" id="showButton">Show the node! </button>
<div id="basicNode" style="width: 200px; background-color: red;">
<b>This is a container of random content to toggle!</b>
</div>
Example 3: Toggle a DOM node with custom animation functions¶
This examples uses the wipeOut and wipeIn functions.
require(["dojo/fx/Toggler", "dojo/fx", "dojo/dom", "dojo/on", "dojo/domReady!"],
function(Toggler, coreFx, dom, on){
var toggler = new Toggler({
node: "basicNode",
showFunc: coreFx.wipeIn,
hideFunc: coreFx.wipeOut
});
on(dom.byId("hideButton"), "click", function(e){
toggler.hide();
});
on(dom.byId("showButton"), "click", function(e){
toggler.show();
});
});
<button type="button" id="hideButton">Hide the node! </button>
<button type="button" id="showButton">Show the node! </button>
<div id="basicNode" style="width: 200px; background-color: red;">
<b>This is a container of random content to toggle!</b>
</div>
