vue+element搭建后台小总结 el-dropdown下拉功能

//全部城市 下拉
//handleCommand下拉事件 all_city点击后显示在上面的数据 
item.label下拉的数据 :command点击传的值 用flag来区分同一个事件的不同处理方法
 
<el-form-item label>
 <el-dropdown @command="handleCommand">
 <span class="el-dropdown-link">
 {{ all_city }}<i class="el-icon-arrow-down el-icon--right" />
 </span>
 <el-dropdown-menu slot="dropdown" align="center">
 <el-dropdown-item
 v-for="item in all_city_list"
 :key="item.value"
 :command="{value:item.value,label:item.label,flag:1}"
 > {{ item.label }}
 </el-dropdown-item>
 </el-dropdown-menu>
 </el-dropdown>
</el-form-item>
 
//全部状态 下拉
<el-form-item label>
 <el-dropdown trigger="click" class="dropdown" @command="handleCommand">
 <span class="el-dropdown-link">
  {{ all_type_org }}<i class="el-icon-arrow-down el-icon--right" />
 </span>
 <el-dropdown-menu
 slot="dropdown" align="center" class="org_select_menu_two">
  <el-dropdown-item

  > {{ item.label }}
 </el-dropdown-item>
 </el-dropdown-menu>
 </el-dropdown>
 </el-form-item>
