vue页面定时刷新 下拉框数据

          mounted() {
            this.getList();
            //自动刷新获取数据
            this.timer = setInterval(() => {
              this.getList();
            }, 10000);
          },
         
          beforeDestroy() {
            // 清除定时器
            clearInterval(this.timer);
            this.timer = null;
          },
          
            <el-select
      v-model="queryParams.userIds"
      placeholder="请选择"
      clearable
      id="inputVal"
      multiple
      @change="doClick"
      @blur="isOpenSHow"
      value-key="userId"
    >
      <el-option
        v-for="item in users"
        :key="item.userId"
        :label="item.userName"
        :value="item"
      >
      </el-option>
    </el-select>
    
    下拉框数据是要字符串 然后提交的时候需要userId
    
    
      doClick(val) {
  console.log(val, "dd");
  let oInput = document.createElement("input");
  let arr;
  if (val) {
    arr = val.map(r => {
      console.log(r, "r");
      return r.userName;
    });
    console.log(arr, "arr;");
  }
  arr.join(",");
  // 创建节点
  oInput.value = arr;

  // 复制

  document.body.appendChild(oInput);
  // 追加到页面

  oInput.select();

  // 选择内容

  document.execCommand("Copy"); // 执行浏览器复制命令
  this.CopyName = val;
  // this.$message({
  //   message: "复制成功",

  //   type: "success"
  // });

  // 提示信息 alert都行比
  oInput.remove();
},
     handleSave() {
  console.log(" this.queryParams.userIds", this.queryParams.userIds);
  let qq = [];
  this.queryParams.userIds.map(r => {
    qq.push(r.userId);
  });
  qq = qq.toString();

  let params = {
    year: this.queryParams.year,
    month: this.queryParams.month,
    controlRoomId: this.queryParams.controlRoomId,
    userIds: qq,
    table: this.table.tableData
  };
  console.log("params", params);

  addPbbc(params).then(res => {
    console.log("res,res", res);
  });
},
