1. 問題
頁面中存在多個(gè)元素（存在父子關(guān)系）監(jiān)聽onScroll時(shí)蜈缤，可能子元素的不生效
2. 解決
The root of the problem is that this.refs.list is a React component, not a DOM node. To get the DOM element, which has the addEventListener() method, you need to call
class ScrollingApp extends React.Component {
_handleScroll(ev) {
console.log("Scrolling!");
}
componentDidMount() {
const list = ReactDOM.findDOMNode(this.refs.list)
list.addEventListener('scroll', this._handleScroll);
}
componentWillUnmount() {
const list = ReactDOM.findDOMNode(this.refs.list)
list.removeEventListener('scroll', this._handleScroll);
}
/* .... */
}
