/** |
|
* ReactLink encapsulates a common pattern in which a component wants to modify |
|
* a prop received from its parent. ReactLink allows the parent to pass down a |
|
* value coupled with a callback that, when invoked, expresses an intent to |
|
* modify that value. For example: |
|
* |
|
* React.createClass({ |
|
* getInitialState: function() { |
|
* return {value: ''}; |
|
* }, |
|
* render: function() { |
|
* var valueLink = new ReactLink(this.state.value, this._handleValueChange); |
|
* return <input valueLink={valueLink} />; |
|
* }, |
|
* _handleValueChange: function(newValue) { |
|
* this.setState({value: newValue}); |
|
* } |
|
* }); |
|
* |
|
* We have provided some sugary mixins to make the creation and |
|
* consumption of ReactLink easier; see LinkedValueUtils and LinkedStateMixin. |
