目标效果如下：

 

 dialog弹出框中增加两个item

          <el-form-item label="维护方式" prop="oprType">
            <el-select class="filter-item" v-model="form.oprType" @change="switchOprType" placeholder="请选择维护方式">
              <el-option v-for="orTyp in  orTypeOptions" :key="orTyp.id" :label="orTyp.labelDefault" :value="orTyp.value"> </el-option>
            </el-select>
          </el-form-item>
          <el-form-item label="属性对象" prop="attrObj">
            <el-input v-model="form.attrObj" v-if="OprTypeFlag == \'input\'" placeholder="请录入需要的属性对象"></el-input>
            <el-select class="filter-item" v-model="form.attrObj" v-if="OprTypeFlag == \'select\'" placeholder="请录入需要的属性对象">
              <el-option v-for="attr in  dictOptions" :key="attr.code" :label="attr.name" :value="attr.code"> </el-option>
            </el-select>
          </el-form-item>
        </el-form-item>

在data->return{}中定义一个全局变量

OprTypeFlag: \'default\',

　　生成dialog时默认为文本框，created(){}方法中

this.OprTypeFlag = \'input\';

　　在methods里面添加切换方法：

    switchOprType() {
      if (event.target.innerText === \'下拉框\') {
        this.OprTypeFlag = \'select\';
        this.form.attrObj = \'\'
      } else {
        this.OprTypeFlag = \'input\';
        this.form.attrObj = \'\'
      }
    }
