2、主要代碼

（1）html

<template>  
   <div class="selOrgCon">
     <div class="center">
       <el-tree :props="props" :load="loadNode" lazy show-checkbox class="selOrgTree">
         <span class="custom-tree-node" slot-scope="{ node }">
           <span class="tree_point">
             {{ node.label }}</span>
         </span>
       </el-tree>
     </div>
</template>

（2）js

<script>
export default {
  name: 'selOrg',
  data() {
    return {
      props: {
        label: 'orgName',
        children: 'zones',
        isLeaf: 'leaf'
      },
    }
  },
  methods: {
    // 懶加載
    loadNode(node, resolve) {
      if (node.level === 0) {
        return resolve([{ orgName: this.$global.yhname, syncId: this.$global.loginName }]);
      }
      if (node.level > 0) {
        // 懶加載下級組織--請求接口
        this.api_shyk.getOrgTree(node.data.syncId, res => {
          // res.data是個數(shù)組
          if (res.code == 0) {
            resolve(res.data);
          }
        })
      }

    }
  }
}
</script>
