vue 查询参数修改但页面没渲染，值已改变

详情页面   路由上带了参数并赋值展示成功，

这个由路由上带的参数修改时，页面没渲染，值已改变,

如果此时去做别的不是路由赋值的参数修改，前面做的修改就刷新出来渲染成功

原代码

 this.crud.query.bankId ="";
 this.crud.query.batchNo ="";
    this.$nextTick(() => {
      this.crud.data = [];
      if (this.$route.query.bankId) {
           //  this.crud.query.bankId = this.$route.query.bankId + "";
    this.$set(this.query, "bankId", this.$route.query.bankId + "");
      }
      if (this.$route.query.batchNo) {
        //     this.crud.query.batchNo = this.$route.query.batchNo;
  this.$set(this.query, "batchNo", this.$route.query.batchNo);    
  }
      this.crud.toQuery();
    });

经过长久测试

发现这样就可以了emmmm

    this.$set(this.crud.query, "bankId", "");
    this.$set(this.crud.query, "batchNo", "");
    this.$nextTick(() => {
      this.crud.data = [];
      if (this.$route.query.bankId) {
        this.crud.query.bankId = this.$route.query.bankId + "";
        // this.$set(this.query, "bankId", this.$route.query.bankId + "");
      }
      if (this.$route.query.batchNo) {
        this.crud.query.batchNo = this.$route.query.batchNo;
      }
      this.crud.toQuery();
    });
