dojo.replaceClass¶
Contents
Removes a class or a list of classes from a DOM node.
Introduction¶
Replaces one or more classes on a node if not present. Operates more quickly than calling dojo.removeClass and dojo.addClass.
Since Dojo 1.7, dojo.replaceClass is exposed via the replace() method of the dojo/dom-class module. An alias is kept in dojo/_base/html for backward-compatibility.
Usage¶
The function takes up to three arguments:
- A DOM node or its node id (as a string).
- A String class name to add, or several space-separated class names, or an array of class names.
- A String class name to remove, or several space-separated class names, or an array of class names.
Dojo 1.7+ (AMD)¶
When using AMD format in a fully baseless application, replace is accessed from the dojo/dom-class module.
require(["dojo/dom-class"], function(domClass){
domClass.replace("someNode", "add1 add2", "remove1 remove2");
});
Alternatively, you can load dojo base in AMD style and continue using dojo.replaceClass in the define or require callback:
require(["dojo"], function(dojo){
dojo.replaceClass("someNode", "add1 add2", "remove1 remove2");
});
Dojo < 1.7¶
dojo.replaceClass("someNode", "add1 add2", "remove1 remove2");
Examples¶
Replace all classes¶
The following example replace all classes with addMe :
// dojo 1.7+ (AMD)
require(["dojo/dom-class"], function(domClass){
domClass.replace("someNode", "addMe");
});
// dojo < 1.7
dojo.replaceClass("someNode", "addMe");
Available in dojo.NodeList() for multiple toggles¶
// dojo 1.7+ (AMD)
require(["dojo/query", "dojo/NodeList-dom"], function(query){
query(".findMe").replaceClass("addMe", "removeMe");
});
// dojo < 1.7
dojo.query(".findMe").replaceClass("addMe", "removeMe");
