elementPlus treeselect相关问题

    <el-tree-select
      placeholder="请选择业务代码"
      :props="{ label: 'transactionName', value: 'transactionCode' }"
      v-model="item.transactionCode"
      node-key="id"
      :data="transactionList"
      :default-expanded-keys="[item.transactionCode]"
      :default-checked-keys="[item.transactionCode]"
      :filter-node-method="filterNodeMethod"
      @node-click="(data) => addSelect(data, index)"
      style="width: 320px"
      filterable
      default-expand-all
      highlight-current
      check-strictly
    >
      <template #default="{ data }">
        {{ data.transactionName }}
        <span style="color: gray; text-align: right">{{ data.transactionCode }}</span>
      </template>
    </el-tree-select>

1、后端返回树形结构不是label、value解决方法如下：

 :props="{ label: 'transactionName', value: 'transactionCode' }"

2、获取到当前选中项的label信息：

@node-click="(data) => addSelect(data, index)"

  let addSelect = (data, index) => {
    formModel.transactionInfo[index].transactionName = data.transactionName
  }

3、编辑、详情页面数据子集回显问题

     :default-expanded-keys="[item.transactionCode]"
     :default-checked-keys="[item.transactionCode]"
