It can be tedious to type out all the boilerplate needed to get the DOM and states in React to synchronize. Luckily, React provides a version of the toolkit with a selection of available addons. This lesson is going to dig into ReactLink, and how this addon can give you two-way binding.

Use addon: ReactLink

1. include the script:

script src="https://fb.me/react-with-addons-0.13.3.js"></script>

2. Add mixin:

mixins: [React.addons.LinkedStateMixin],

3. Use valueLink={this.linkState(‘name‘)} instead of ‘ref‘ and ‘onChange‘:

<input valueLink={this.linkState(‘name‘)} type="text" placeholder="Name" />

Code:

<!doctype html><html lang="en"><head>    <meta charset="UTF-8">    <title>React Lesson 15: dynamically create componenets</title>    <script src="https://fb.me/react-with-addons-0.13.3.js"></script>    <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.13.3/JSXTransformer.js"></script>    <style>        body {            margin: 25px;        }    </style></head><body><div id="panel"></div><script type="text/jsx">    /** @jsx React.DOM */    var App = React.createClass({        mixins: [React.addons.LinkedStateMixin],        getInitialState:function(){            return {                name: ‘‘,                email: ‘‘            }        },        render:function(){            return (                <form>                    <div>                        <input valueLink={this.linkState(‘name‘)} type="text" placeholder="Name" />                        <label>*{this.state.name}*</label>                    </div>                    <div>                        <input valueLink={this.linkState(‘email‘)} type="text" placeholder="Email" />                        <label>*{this.state.email}*</label>                    </div>                </form>            );        }    });    React.render(<App />, document.getElementById(‘panel‘));</script></body></html>
