如果你没有走网络请求,也就是没有render两次,就使用注释掉的两个方法即可。或者两个都写一遍。

/** * Created by wuyakun on 2017/4/27. */ import React from 'react'; class GoodsDetail extends React.Component { constructor(props) { super(props); this.state = { goods_desc: '', }; } //为什么会走更新的,就是因为Goods render了两次(初始-网络数据) // componentWillMount() { // this.setState({ // goods_desc: this.props.goods_desc ? this.props.goods_desc : '', // }); // } // 组件更新props componentWillReceiveProps(value) { this.setState({ goods_desc: value.goods_desc ? value.goods_desc : '', }); } // componentDidMount() { // document.getElementById("goods_detail_content").innerHTML = this.state.goods_desc; // } //更新完毕 componentDidUpdate() { document.getElementById("goods_detail_content").innerHTML = this.state.goods_desc; } render() { return ( <div> <div className="pro_detial"> <h3><i />课程详情</h3> <div className="pro_con"> <div id="goods_detail_content"/> </div> </div> </div> ); } } export default GoodsDetail;
