vue+element下拉选项添加点击事件可跳转或触发事件

1、附上代码，想用直接复制方便 

 <el-dropdown @command="handleCommand">

          <img

            v-if="this.$store.state.deptId == 1"

            class="el-dropdown-link"

            src="../assets/20191211图标/20191211图标/系统设置.png"

            style="width:90px;height:50px"

          />

          <el-dropdown-menu slot="dropdown">

            <el-dropdown-item command="userGroup">用户分组管理</el-dropdown-item>

            <el-dropdown-item command="userGroup2">PMS信息导入</el-dropdown-item>

            <el-dropdown-item command="userGroup3">历史修改记录</el-dropdown-item>

            <el-dropdown-item command="userGroup4">数据自动更新</el-dropdown-item>

          </el-dropdown-menu>

        </el-dropdown>

2、

    handleCommand(cmditem) {

      if (!cmditem) {

        this.$message("菜单选项缺少command属性");

        return;

      }

      switch (cmditem) {

        case "userGroup":

          this.userGroup();

          break;

        case "userGroup2":

          this.userGroup2();

          break;

        case "userGroup3":

          this.userGroup3();

          break;

        case "userGroup4":

          this.userGroup4();

          break;

      }

    },

 

3、

  userGroup() {

      this.$router.push("/dept_user");

    },

    userGroup2() {

      this.centerDialogVisible = true;

    },

    userGroup3() {

      this.$router.push("/history");

    },

    userGroup4() {

      this.updatas();

      this.centerDialogVisibled = true;

    },
