This time I will show you how to implement pull-up loading in WeChat applet development. What are the precautions for pull-up loading in WeChat applet development? The following is a practical case, let’s take a look.

My current company's project is an e-commerce applet, which can be refreshed by pulling down. The official website clearly states that it cannot be used with scroll-view at the same time. I used onReachBottom and scroll-view's bindscrolltolower out of the blue. After my practice, I recommend everyone to use onReachBottom. If there are pull-down refreshes in some tabs, it is very convenient to directly enter the code:

onReachBottom() {        let isPush = this.data.index,
            val = this.data.inputVal;
        this.setData({
            isBtnShow: true
        });        if (isPush ==1) {            let num = this.data.limitIndex;
            this.setData({                limitIndex: num+1
            })
        //关于上拉加载的性能优化            setTimeout(()=>{
                    // 给后端传下拉刷新的次数+1
                    const data = {                        limitIndex: this.data.limitIndex
                    };
                    utils.sendRequest(api.AllGoodsUrl, data, this.handleReachBottom.bind(this));
            },1500)
        };        if (val != &#39;&#39;) {            setTimeout(()=>{                let num = this.data.limitIndex;
                    this.setData({                        limitIndex: num+1
                    })
                    // 给后端传下拉刷新的次数+1
                    const data = {                        limitIndex: this.data.limitIndex,
                         data:{
                            name: this.data.inputVal,
                        }
                    };
                    utils.sendRequest(api.AllGoodsUrl, data, this.handleLoadMore.bind(this));
            },1500)
        };
    },
