前情提示
vue2
hubilderx4.29最新版本
mescroll-uni-1.3.8目前最新版本
使用mescroll-body支持原生组件,性能更好,非常容易接入,官方也提供了很多demo示例。
快速安装
使用uni_modules直接下载导入。不需要配置其他任何地方,不需要配置不必配置pages.json。
业务接口示例
返回要有总页码、或者总条数,这里用的总条数
{
"success": true,
"message": "",
"code": 200,
"result": {
"records": [
{
"id": "1849444662765731841",

效果图
业务界面代码
如果你引入了uview,基本可以完全复制使用
<template>
<view>
<!--标题和返回-->
<cu-custom :bgColor="NavBarColor" isBack>
<block slot="backText">返回</block>
<block slot="content">育肥猪信息</block>
</cu-custom>
<view class="search">
<u-search v-model="keywords" @custom="search" @search="search"></u-search>
</view>
<!--滚动加载列表-->
<view class="btn-plus" @click="navTo('pdtjPigYfInfoForm')">
<u-icon name="plus-circle-fill" size="90" color="#3d87ff"></u-icon>
</view>
<mescroll-body ref="mescrollRef" top="105rpx" @init="mescrollInit" :up="upOption" :down="downOption"
@down="downCallback" @up="upCallback">
<u-cell-group class="list" :border="false">
<u-swipe-action :options="options2" v-for="(item, index) in list" :key="item.id" :index="index"
@click="optionsClick">
<u-cell-item :arrow="true" @click="navTo('pdtjPigYfInfoForm?id='+item.id)">
<text slot="title">{{item.name || item.id}}</text>
<text slot="label">创建者:{{item.createBy}} | 时间:{{item.createTime}}</text>
</u-cell-item>
</u-swipe-action>
</u-cell-group>
</mescroll-body>
</view>
</template>

@/common/mixin/Mixin.js主要用了请求业务接口,和配置mescroll的options。
