效果图
之前已经写过用Vue实现图上效果的方法，此篇为用knockout.js实现上图效果的方法，同样通过模板将数据绑定到页面。
模板代码
<script type="text/html" id="ko-temp">
<div class="tem">
<div class="tem-p" >
<div data-bind="event:{click:$root.toggleClick}"><i data-bind="style:{'visibility':number!=0"></i><span data-bind="text:name"></span></div>
<!--绑定数据-->
<div><span data-bind="text:energyone"></span></div>
<div><span data-bind="text:energytwo"></span></div>
<div><span data-bind="text:energythree"></span></div>
<!--绑定class，使数值显示出区分-->
<div><span data-bind="css:{isgreen:huanRatio<0,isred:huanRatio>100},text:huanRatio+'%'"></span></div>
<div><span data-bind="css:{isgreen:tongRatio<0,isred:tongRatio>100},text:tongRatio+'%'"></span></div>
</div>
<!--ko if:isFolder-->
<div class="tem-c" data-bind="template:{name:'ko-temp',foreach: child}" ></div>
<!--/ko-->
</div>
</script>
请对比之前一篇Vue的方法，了解两种方式模板绑定方式的不同。
模板写完，在页面上使用模板。
html代码
<div class="component-div" data-bind="template:{name:'ko-temp',foreach: ko_vue_data()}"></div>
