uni-app 上拉加载跳转页面

上拉触底生命周期：onReachBottom
具体实现：
模拟加载组件：

<template>
    <view class="uni-load-more">
        <view v-show="status === 'loading' && showIcon" class="uni-load-more__img">
            <view class="load1 load">
                <view :style="{ background: color }" class="uni-load-view_wrapper" />

引用：

<uni-load-more :status="status" :color="loadingcolor" :content-text="contentText" v-if="loading"/>

import uniLoadMore from '../../component/uni-load-more.vue'

data() {
    return {
        status:'',
        loadingcolor:'#006B69',
        contentText: {
            contentrefresh: '',
            contentnomore: 'Reached the bottom of the page, pull up to load the next page'
        },
        loading:false,
        toustrart:0,
        touend:0,
        bottoms:false,
        bot:false
    }
},

components:{
    uniLoadMore
}

上拉加载，跳转下一页实现：

第一步：触底时，给一个提示,到达页面底部

onReachBottom(){
    this.loading=true
    this.status='noMore'
    this.loadingcolor="#777777";
    this.bottoms = true;
    console.log('onreachbottom')
},

第二步：实现上拉，主要利用手指进行上拉动作时，开始和结束的距离判断
具体实现：

touchstart(event){
    this.toustrart = event.touches[0].clientY
},
touchmove(event){
    let  tag = event.touches;
    this.touend = tag[0].clientY
},
touchend(){
        if(this.toustrart - this.touend < 0){
        this.bottoms = false
    }
    if(this.bottoms){
        if(this.toustrart - this.touend > 50){
            this.loading=true
            this.status='loading'
            this.loadingcolor="#777777";
            var self = this
            setTimeout(function(){
                uni.navigateTo({
                     url: '../points/points'
                });
                self.status = 'noMore'
            },1000)
        }
    }
                
}

第三步，页面初始化时，给this.toustrart 和 this.touend清零，防止返回时还存在，点击就能跳转

onShow() {
    this.toustrart = 0;
    this.touend = 0;
},
