el-dropdown-menu如何获取下拉选择的项

el-dropdown-menu 可以通过监听下拉菜单的 select 事件来获取用户选择的项，具体代码如下：

<el-dropdown @command="handleCommand">
  <span class="el-dropdown-link">
    下拉菜单<i class="el-icon-arrow-down el-icon--right"></i>
  </span>
  <el-dropdown-menu slot="dropdown">
    <el-dropdown-item command="item1">选项一</el-dropdown-item>
    <el-dropdown-item command="item2">选项二</el-dropdown-item>
    <el-dropdown-item command="item3">选项三</el-dropdown-item>
  </el-dropdown-menu>
</el-dropdown>

<script>
export default {
  methods: {
    handleCommand(command) {
      console.log(command); // 获取用户选择的项
    }
  }
}
</script>
