在react-grid-layout中覆盖onMouseDown

Question

How do I override onMouseDown for a GridItem?

I have something like this:

class TrackItem extends React.Component {
    onMouseDown(e) {
        this.props.onMouseDown.apply(e);
    }
    render() {
        return <div onMouseDown={this.onMouseDown.bind(this)}>item</div>;
    }
}

Which yields the error:

react-draggable.js:1050 Uncaught TypeError: Cannot read property 'button' of undefined

Answer 1

事实证明，我不需要apply ：

this.props.onMouseDown(e);
