-Let's try jQuery.
-
-The general concept is simple: treat `componentDidMount` as jQuery's `ready` and tag your component with a `ref`. Then, call its `getDOMNode`. Notice that with `ref` (component scope), you don't need selectors anymore!
-
-```js
-/** @jsx React.DOM */
-
-var ToggleBox = React.createClass({
-  componentDidMount: function() {
-    $(this.refs.dialogueBox.getDOMNode()).hide().fadeIn(500);
-  },
-  render: function() {
-    return (
-      <div>
-        <button onClick={this.handleClick}>Toggle me!</button>
-        <div
-          ref="dialogueBox"
-          style={{border: '1px solid gray', width: 90, height: 90, padding: 10}}
-        >
-          Easy!
-        </div>
-      </div>
-    );
-  },
-  handleClick: function() {
-    $(this.refs.dialogueBox.getDOMNode()).stop().toggle(200);
-  }
-});
-
-React.renderComponent(<ToggleBox />, mountNode);
-```
-
-Use libraries like jQuery for things like animation and AJAX, but preferably, don't manipulate the DOM with it. There are mostly likely better way to achieve that if you're already using React.

-### Problem
-You want to incorporate React with jQuery for, say, its animation effects.

-### Solution
-The general concept is simple: treat `componentDidMount` as jQuery's `ready` and tag your component with a `ref`. Then, call its `getDOMNode`. Notice that with `ref` (component scope), you don't need selectors anymore!

-        <button onClick={this.handleClick}>Toggle me!</button>
-        <div
-          ref="dialogueBox"
-          style={{border: '1px solid gray', width: 90, height: 90, padding: 10}}
-        >

-        </div>
