Answer 1

<div style="float" id="app">&nbsp; &nbsp; <span class="structure-alldata">全部数据</span>&nbsp; &nbsp; <br />&nbsp; &nbsp; <span class="structure-number"><span class="structure-individual">{{list.length}}</span>个</span></div>var vm = new Vue({&nbsp; &nbsp; el : '#app',&nbsp; &nbsp; data : {&nbsp; &nbsp; &nbsp; &nbsp; list : [] // 初始值为0&nbsp; &nbsp; }});然后如果需要读接口可以直接 更改将接口列表赋值个 list就可以了
