繼React.js上的微軟教程是here。React.js未定義的函數
我想映射一個列表的功能,所以它重複了很多次。
這是什麼代碼的主片的錯誤是:
{[1,2,3].map(this.renderInboxItem)}
我得到的錯誤是:
bundle.js:8488 Uncaught TypeError: undefined is not a function
這裏是全碼:
var React = require('react');
var ReactDOM = require('react-dom');
var sample = require('./sample-data.js');
var App = React.createClass({
renderInboxItem: function(){
return <h1> Test </h1>
},
getInitialState: function() {
return {
"humans":{},
"store":{}
};
},
loadSampleData: function(){
this.setState(sample);
},
render : function() {
return (
<div>
<div id="header"></div>
<button onClick={this.loadSampleData}> loadSampleData </button>
<div className="container">
<div className="column">
<InboxPane humans={this.state.humans} />
</div>
<div className="column"></div>
<div className="column"></div>
</div>
</div>
)
}
});
var InboxPane = React.createClass({
render : function() {
return (
<div id="inbox-pane">
<h1>Inbox</h1>
<table>
<thead>
<tr>
<th>Chat Received</th>
<th>Name</th>
<th>Status</th>
</tr>
</thead>
<tbody>
{[1,2,3].map(this.renderInboxItem)}
</tbody>
</table>
</div>
)
}
});
var InboxItem = React.createClass({
render: function(){
return (
<tr>
<td>5PM</td>
<td>Rami Loves Pizza</td>
<td>Order Sent</td>
</tr>
)
}
});
ReactDOM.render(<App/>, document.getElementById('main'));
