vue实现触底查询功能

methods: {
    getdata() {
      let status=3;
      this.queryParams.params={
        status:status,
        passFactory: this.$store.state.user.werksName 
      }
      let params = JSON.parse(JSON.stringify(this.queryParams));
      api.getPageList(params).then((res) => {
        if (res.success) {
          this.dataList = res.data.content;
        } else {
          Toast.fail({
            message: res.msg
          });
        }
      });
    },
     onLoad() {//触底查询
      this.queryParams.page += 1; 
      let _this = this;
      let status=3;
      this.queryParams.params={
        status:status,
        passFactory: this.$store.state.user.werksName 
      }
      let params = JSON.parse(JSON.stringify(this.queryParams));
      api.getPageList(params).then((res) => {
       if(res.success){
          this.dataList = this.dataList.concat(res.data.content);
          if (this.dataList.length >= res.data.totalElements) {
            this.finished = true;
          } else {
            this.finished = false;
          }
          this.loading = false;
        }
      });
    },
