1、給級聯(lián)菜單添加 ref 和change事件

 <el-col :xs="24" :sm="22" :md="22" :lg="22" :xl="12">
     <el-form-item label="所屬部門" prop='orgdept_code'>
         <el-cascader 
            class="editInput" 
            v-model="drawerUserInfo.orgdept_code" 
            :options="spareTree" 
            :props="multistage" 
            filterable 
            size="small" 
            placeholder="請輸入所屬部門" 
            clearable 
            ref="cascaderRef" 
            @change="spareTreeChange">
         </el-cascader>
     </el-form-item>
</el-col>

?2、 在事件中獲取label?數(shù)據(jù)

spareTreeChange(value){
    let that = this
    if(value){
        console.log(
            that.$refs.cascaderRef.getCheckedNodes()[0].pathLabels
        )
    }
},

?3、控制臺輸出
