Vue組件模板形式實(shí)現(xiàn)對(duì)象數(shù)組數(shù)據(jù)循環(huán)為樹(shù)形結(jié)構(gòu)(實(shí)例代碼)

這篇文章主要介紹了Vue組件模板形式實(shí)現(xiàn)對(duì)象數(shù)組數(shù)據(jù)循環(huán)為樹(shù)形結(jié)構(gòu),本文用vue實(shí)現(xiàn)方式，非常不錯(cuò)，具有參考借鑒價(jià)值，需要的朋友可以參考下

數(shù)據(jù)結(jié)構(gòu)為數(shù)組中包含對(duì)象--樹(shù)形結(jié)構(gòu)，用Vue組件的寫(xiě)法實(shí)現(xiàn)以下的效果：

樹(shù)形列表，縮進(jìn)顯示層級(jí)，第5級(jí)數(shù)據(jù)加底色，數(shù)據(jù)樣式顯色，點(diǎn)擊展開(kāi)折疊數(shù)據(jù)。本文為用Vue實(shí)現(xiàn)方式，另有一篇為用knockout.js的實(shí)現(xiàn)方法。

html代碼

 <div id="table-component-div">
   <table-component v-for="item in data1" v-bind:list="item"></table-component>
 </div>

組件模板代碼

<script type="text/x-template" id="table-component-template">
  <div class="tem">
    <div class="tem-p">
      <div v-on:click="toggleClick"><i v-bind:style="{'visibility':list.number!=0?'visible':'hidden'}">{{list.number}}</i><span>{{list.name}}</span></div>
      <!--綁定數(shù)據(jù)-->
      <div><span>{{list.energyone}}</span></div>
      <div><span>{{list.energytwo}}</span></div>
      <div><span>{{list.energythree}}</span></div>
      <!--綁定class，使數(shù)值顯示出區(qū)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">
      <!-- 子組件 -->
      <table-component v-for="itemc in list.child" :list="itemc"></table-component>
    </div>
  </div>
</script>

      }
    })

數(shù)據(jù)顯示完畢，接下來(lái)是樣式效果，縮進(jìn)顯示層級(jí)及底色顯示。
