getDefaultProps无法使用reactjs
我正在尝试使用react.js为下面的示例使用getDefaultProps方法,但我发现它不适合我: HTML:getDefaultProps无法使用reactjs,reactjs,react-jsx,Reactjs,React Jsx,我正在尝试使用react.js为下面的示例使用getDefaultProps方法,但我发现它不适合我: HTML: Javascript: var RecentChangesTable = React.createClass({ render: function() { return ( < table className = 'table' > { this.props.children } < /table>); }

有人能告诉我这里缺少什么吗。我更新了下面提到的代码,它对我起了作用:

render: function() {
return ( < table className = 'table' > {
this.props.children

} < /th>;
}
});

render: function() {
var headings = this.props.headings.map(function(name,index) {
return <RecentChangesTable.Heading key={index} heading = {

你是说ReactDOM.render
?您的应用程序
组件也会返回此.props.headers
,但您从未使用过它吗?而且你的代码非常难读。你是从哪里得到这样的想法的?你已经在应用程序中定义了getDefaultProps,但从未使用过它。我尝试了各种方法来阅读getDefaultProps,但在这里它对我不起作用。任何代码示例都可以帮助我。
