这篇文章主要介绍Vue组件模板形式如何实现对象数组数据循环为树形结构，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
数据结构为数组中包含对象--树形结构，用Vue组件的写法实现以下的效果：
树形列表，缩进显示层级，第5级数据加底色，数据样式显色，点击展开折叠数据。本文为用Vue实现方式，另有一篇为用knockout.js的实现方法。
html代码
<div id="table-component-div">
<table-component v-for="item in data1" v-bind:list="item"></table-component>
</div>组件模板代码
<script type="text/x-template" id="table-component-template">
<div class="tem">
<div class="tem-p">
<div v-on:click="toggleClick"><i v-bind:>{{list.number}}</i><span>{{list.name}}</span></div>
<!--绑定数据-->
<div><span>{{list.energyone}}</span></div>
<div><span>{{list.energytwo}}</span></div>
<div><span>{{list.energythree}}</span></div>
<!--绑定class，使数值显示出区分-->
<div><span v-bind:class="{'isgreen':list.huanRatio<0,'isred':list.huanRatio>100}">{{list.huanRatio}}<em>%</em></span></div>
<div><span v-bind:class="{'isgreen':list.tongRatio<0,'isred':list.tongRatio>100}">{{list.tongRatio}}<em>%</em></span></div>
</div>
<div class="tem-c">
<!-- 子组件 -->
<table-component v-for="itemc in list.child" :list="itemc"></table-component>
</div>
</div>
</script>JavaScript代码
var ko_vue_data=[

Vue.component('table-component', {
template:"#table-component-template",//模板
props:['list'],//传递数据
computed:{//计算属性
isFolder: function () {//判断数据有没有子集，此效果中暂没用到，有需要的可以看下具体使用方式
return this.list.child && this.list.child.length > 0;
}
},
methods:{
toggleClick:function(event){
event.stopPropagation();//阻止冒泡
var _this = $(event.currentTarget);//点击的对象
if (_this.parent().next().is(":visible")) {
_this.parent().next().slideUp();
} else {
_this.parent().next().slideDown();
}
}
}
});
new Vue({
el:"#table-component-div",//挂载dom
data:{
data1:ko_vue_data//数据
}
})数据显示完毕，接下来是样式效果，缩进显示层级及底色显示。
