React Js string字符串转换为html dom

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 /4/27.*/import React from 'react';class GoodsDetail extends ponent {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propscomponentWillReceiveProps(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;
