用Python编写和读取相同的csv文件(Writing & Reading the same csv file in Python)

你可以使用
this.props.children
来渲染组件的子控件。 喜欢这个:var Control = React.createClass({ render: function() { return <div>{ this.props.children }</div>; } }); var App = React.createClass({ render: function() { return <Control><h1>child control</h1></Control>; } });
You can use
this.props.children
to render component's child controls. Like this:var Control = React.createClass({ render: function() { return <div>{ this.props.children }</div>; } }); var App = React.createClass({ render: function() { return <Control><h1>child control</h1></Control>; } });
