本文实例为大家分享了小程序实现分页查询列表的模板，供大家参考，具体内容如下
list.wxml
<view class="home-main">
<!-- 搜索 -->
<view class="search-bar">
<view class="search-bar-form">
<image class="search-img" src="/images/search-icon.png"></image>
<input class="search-input" type="text" placeholder="搜索图片、文章、视频" confirm-type="search"></input>
</view>
</view>
<!-- 列表 -->
<view class="classify-list-all">
<view wx:for="{{list}}" wx:key="id" data-item='{{item}}' class="classify-list flex align-center" bindtap="goClassify">
<image class="classify-list-image" src="{{item.logo}}"></image>
<view class="classify-list-main">
{{item.name}}
</view>
</view>
</view>
</view>

import Api from "../../../config/api";
import Http from "../../../utils/http";
Page({
data: {
formData: {
size: 10,//分页，一页10条
current: 1,//当前页数
},

},
onLoad() {
//首次请求
this.queryListPage();
},
onPullDownRefresh() {
//下拉刷新
this.setData({ 'formData.current': 1 });
this.queryListPage();
},
onReachBottom() {
//页面上拉触底事件的处理函数
this.queryListPage();
},
goClassify(e) {
wx.navigateTo({

queryListPage() {
//请求列表

item.name = item.name + '处理后数据';
return item;
});

}
