這篇文章主要介紹了knockoutjs模板實現(xiàn)樹形結構列表的實現(xiàn)代碼，非常不錯，具有參考借鑒價值，需要的朋友參考下吧

數(shù)據(jù)結構

/*數(shù)據(jù)*/
 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: []
        }
       ]
      }
     ]
    }
   ]
  }
 ];

效果圖

之前已經(jīng)寫過用Vue實現(xiàn)圖上效果的方法，此篇為用knockout.js實現(xiàn)上圖效果的方法，同樣通過模板將數(shù)據(jù)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(shù)據(jù)-->
   <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(shù)值顯示出區(qū)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(shù)據(jù)*/
 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(shù)據(jù)非常方便。
