This module defines the core dojo DOM class API. The standard return variable for this module is domClass.

Features

AMD Features

• domClass.contains

  Returns whether or not the specified classes are a portion of the class list currently applied to the node.

• domClass.add

  Adds the specified classes to the end of the class list on the passed node. Will not re-apply duplicate classes.

• domClass.remove

  Removes the specified classes from node. No domClass.contains check is required.

• domClass.replace

  Replaces one or more classes on a node if not present. Operates more quickly than calling domClass.remove and domClass.add

• domClass.toggle

  Adds a class to node if not present, or removes if present. Pass a boolean condition if you want to explicitly add or remove. Returns the condition that was specified directly or indirectly.

Legacy features are set in dojo/_base/html.

Examples

Here is an example of using domClass.contains to determine if a DOM node contains a particular class.

require(["dojo/dom-class"], function(domClass){
  if (domClass.contains("someNode", "aSillyClassName")){
    console.log("someNode contains aSillyClassName");
  }else{
    console.log("someNode does not contain aSillyClassName");
  }
});

require(["dojo/dom-class"], function(domClass){ if (domClass.contains("someNode", "aSillyClassName")){ console.log("someNode contains aSillyClassName"); }else{ console.log("someNode does not contain aSillyClassName"); } });
