效果圖

之前已經寫過用Vue實現圖上效果的方法，此篇為用knockout.js實現上圖效果的方法，同樣通過模板將數據綁定到頁面。

模板代碼

<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?'visible':'hidden'},text:number"></i><span data-bind="text:name"></span></div>
 <!--綁定數據-->
 <div><span data-bind="text:energyone"></span></div>
 <div><span data-bind="text:energytwo"></span></div>
 <div><span data-bind="text:energythree"></span></div>
 <!--綁定class，使數值顯示出區分-->
 <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>

請對比之前一篇Vue的方法，了解兩種方式模板綁定方式的不同。

模板寫完，在頁面上使用模板。

html代碼

<div class="component-div" data-bind="template:{name:'ko-temp',foreach: ko_vue_data()}"></div>

JavaScript代碼

/*數據*/
 var ko_vue_data=[
 {
 name: "總能耗",
 number:"0",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: [
 {
 name: "租戶電耗",
 number:"1",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: []
 },
 {
 name: "公共用電",
 number:"2",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: [
 {
 name: "暖通空調",
 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: "冷水機組",
 number:"2.1.1.1",
 energyone: 14410,
 energytwo: 1230,
 energythree: 1230,
 huanRatio: -36.8,
 tongRatio: 148.5,
 child: []
 }
 ]
 },
 {
 name: "熱力站",
 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);//默認展開
 for(var j=0;j<temp.child.length;j++){
 addAttribute(temp.child);
 }
 }
 }
 addAttribute(ko_vue_data);
 /*視圖模型*/
 function viewModel() {
 var self=this;
 self.ko_vue_data=ko.observableArray(ko_vue_data);
 self.toggleClick=function (event) {//展開折疊效果
 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樣式同之前一篇Vue的一致，在這里就不在贅述，如有需要可查看之前一篇。到此兩種方式算是全部寫完，在報表多的頁面，對于以上代碼，稍加修改即可復用，綁定數據非常方便。
