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"> <div> <div > <div data-bind="event:{click:$root.toggleClick}"><i data-bind="style:{'visibility':number!=0?'visible':'hidden'},text:number"></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 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 data-bind="template:{name:'ko-temp',foreach: ko_vue_data()}"></div>
JavaScript代码
/*数据*/ var ko_vue_data=[ { name: "总能耗", number:"0", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [ { name: "租户电耗", number:"1", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [] }, { name: "公共用电", number:"2", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [ { name: "暖通空调", number:"2.1", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [ { name: "冷站", number:"2.1.1", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [ { name: "冷水机组", number:"2.1.1.1", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [] } ] }, { name: "热力站", number: "2.1.2", energyone: 14410, energytwo: 1230, energythree: 1230, huanRatio: -36.8, tongRatio: 148.5, child: [] } ] } ] } ] } ]; function addAttribute(dst){ for(var i=0;i<dst.length;i++){ var temp=dst[i]; temp.isFolder=ko.observable(true);//默认展开 for(var j=0;j<temp.child.length;j++){ addAttribute(temp.child); } } } addAttribute(ko_vue_data); /*视图模型*/ function viewModel() { var self=this; self.ko_vue_data=ko.observableArray(ko_vue_data); self.toggleClick=function (event) {//展开折叠效果 window.event? window.event.cancelBubble = true : event.stopPropagation(); var isFolder=event.isFolder(); if(isFolder){ event.isFolder(false); }else { event.isFolder(true); } } } ko.applyBindings(new viewModel());
css样式同之前一篇Vue的一致，在这里就不在赘述，如有需要可查看之前一篇。到此两种方式算是全部写完，在报表多的页面，对于以上代码，稍加修改即可复用，绑定数据非常方便。
