如何爲GridItem重寫onMouseDown?在react-grid-layout中覆蓋onMouseDown
我有這樣的事情:
class TrackItem extends React.Component {
onMouseDown(e) {
this.props.onMouseDown.apply(e);
}
render() {
return <div onMouseDown={this.onMouseDown.bind(this)}>item</div>;
}
}
其產生錯誤:
react-draggable.js:1050 Uncaught TypeError: Cannot read property 'button' of undefined
