uni-app微信小程序分页上拉加载更多的实现
首先我们需要下载一个uni-app的加载更多的插件 uniLoadMore
插件内容如下:
新建一个文件命名为：uni-load-more
大家可以像我一样放在这里
插件的内容如下:
<template>
<view class="uni-load-more" @click="onClick">
<!-- #ifdef APP-NVUE -->
<loading-indicator v-if="!webviewHide && status === 'loading' && showIcon" :style="{color: color,width:iconSize+'px',height:iconSize+'px'}" :animating="true" class="uni-load-more__img uni-load-more__img--nvue"></loading-indicator>
<!-- #endif -->
<!-- #ifdef H5 -->
<svg width="24" height="24" viewBox="25 25 50 50" v-if="!webviewHide && (iconType==='circle' || iconType==='auto' && platform === 'android') && status === 'loading' && showIcon"
:style="{width:iconSize+'px',height:iconSize+'px'}" class="uni-load-more__img uni-load-more__img--android-H5">
<circle cx="50" cy="50" r="20" fill="none" :style="{color:color}" :stroke-width="3"></circle>
</svg>
<!-- #endif -->
<!-- #ifndef APP-NVUE || H5 -->
<view v-if="!webviewHide && (iconType==='circle' || iconType==='auto' && platform === 'android') && status === 'loading' && showIcon"
:style="{width:iconSize+'px',height:iconSize+'px'}" class="uni-load-more__img uni-load-more__img--android-MP">

<!-- #endif -->

接下来我们可以直接在我们的项目中引入
import uniLoadMore from '../../components/uni-load-more/uni-load-more.vue'
注册组件：
components: {
uniLoadMore
},
接下来我们直接在文中引用：
<uni-load-more :status="status" :content-text="contentText" />
然后在data中定义初始页码和一个空的数组，还有contentText:
data(){
return{
contentText: {
contentdown: '上拉加载更多',
contentrefresh: '',
contentnomore: '没有更多'
},
page:1,
isEnd:false, //isEnd用于判断是否还有数据，没有数组停止数组请求
newArrData:[]
}
}
调用uni-app的onReachBottom函数：
onReachBottom() {
this.status = 'more'; //设置sataus是更多
this.getFunction(); //加载的数据
},
methods:{
getFunction(){
if(this.isEnd){
return
}
uni.request({
}).then(res =>){
newArrData=res.data;
this.list=this.list.concat(newArrData); //在页面中我们循环list数组就可以了
if(res.data.length<=0){
this.isEnd=true;
this.status="noMore";
}else{
this.page++
}
}
}
}
上面那种方法适用于只有一个分页数据，当我们牵扯到tab切换进行分页的时候，我们需要对页码进行处理，保证我们每次切换tab栏时，页码都是从1开始的。
可以在tab栏切换的时候进行判断：
在data中定义一个数据currentTab用于存放当前的tab栏的index
clickTab(data){
//如果当前点击的不变，则不重置page
if (this.currentTab === data.detail.index) {
return
}
this.currentTab=data.detail.index;
this.page=1;
this.getFunction(参数);
}
这种方法在页面加载的时候我们只能加载默认的tab栏数据，但是如果我们感觉点击切换tab栏数据加载太慢的话，可以把tab栏的方法分开写，定义多个this.getFunction(),这样就跟第一种情况一样了，在页面加载的时候也可以把所有的tab栏数据都加载出来，在页面向上滑动时在加载数据。当这多个方法在页面中，如果我们不想分开写多个数组渲染，也可以用同一个数组渲染。写一个监听器，监听currentTab的变化
例如:
watch: {
currentTab: {
immediate: true,
deep: true,
handler(newVal, oldVal) {
if (newVal === 1) {
this.netMeetingDataLength = this.netMeetingDataLength2;
} else if (newVal === 0) {
this.netMeetingDataLength = this.netMeetingDataLength3;
} else if (newVal === 2) {
this.netMeetingDataLength = this.netMeetingDataLength1;
}
}
}
},
在每次点击切换时把其他tab栏对应的值赋值给netMeetingDataLength数组，然后在页面中循环netMeetingDataLength数组就可以了
