1.設定定義屬性值  :data-value=".."

<ul class="header-ul">
          <li class="flexcss" v-for="(list,index) in child" :data-value="list.name" @click="changeContent(index,list.name)">{{list.name}}</li>
        </ul>

2.

    methods: {
          changeHeaderContent(index,name){
              console.log('cht',index)
              console.log('chaname',name)
}
 

上面是迴圈體中獲取。

data () {
    return {
      msg: 'Welcome to Your Vue.js App',
      name:'czj',
    }
  },

   gotoDetail:function(ev){
