关于vue的jsx语法

react的jsx语法很好用,但是vue的jsx语法就不是很好用了。

vue的jsx语法不能实现双向数据绑定以及各种比如v-for指令,只能自己用代码用另一种方式实现出来。着实是费了一些功夫,现在来说一下我使用vue的jsx语法过程中用到的东西吧,当个记录,也方便以后查看。

因为我的项目用得是iview的框架,所以这里用的是iview的table组件+vue2.0+jsx

以下是代码:

  

  1 //以下是table
  2     <div style="100%;">
  3           <i-table border :columns="columns2" :data="data2" style="100%;"></i-table>                
  4     </div>
  5 
  6 
  7 //以下是data数据
  8 
  9 export default{
 10         data(){
