el-cascader多次点击页面奔溃卡死？

Question

多次狂点击导致页面奔溃无响应，是什么原因造成的？

handleOrgChange() {
      this.$refs.cascader.dropDownVisible = false;
      if (this.organId) {
        getOrgTitlesList({
          organId: this.organId,
        }).then((res) => {
          this.titleList = res || [];
        });
        // const job = this.jobList.find((item) => item.id === this.jobId);
        // this.jobName = job.jobName;
      } else {
        this.titleList = [];
        // this.jobRoleList = [];
      }
      this.titleId = '';
    },
