2、获取数据

 data() {
    return {
    moveLists: [],
      moveItem: {
        moveId: "",
        moveStartOffice: "",
        moveEndOffice: "",
        moveJobNum: "",
        departmentStartName: "",
        departmentEndName: "",
      },
    }
   }
   //连接接口获取后台数据
    getMovedata() {
      this.loading = true;
      this.moveJobNum = JSON.parse(localStorage.getItem("baseJobNum"));
      MoveInfos(this.moveJobNum)
        .then((res) => {
          this.loading = false;
          if (res.data.status == 500) {
            this.$message({
              type: "info",
              message: res.data.message,
            });
          } else {
            this.moveLists = res.data;
          }
        })
        .catch((err) => {
          this.loading = false;
          this.$message.error("数据加载失败，请稍后再试！");
        });
