vue中的mescroll搜索运用及各种填坑处理
父组件处理:
<template> <div class="wrap"> <!-- 搜索框 --> <div class="searchInputArea"> <div class="searchBarBox"> <div class="inputWrap" > <form onsubmit="javascript:return false" action> <input :placeholder = "placeholderStr" type="search" ref = "input" v-model="keyword" /> <span class="clearBtn" v-show="keyword" @click="clear"></span> </form> </div> </div> </div> <div class="myFastChoiceBlock" v-show="!keyword"> <!-- 最近伙伴和我的关注 --> <fast-choice :successInvite="successInvite" @invite="inviteClick"></fast-choice> </div> <div class="searchContainer"> <search-content :searchName="keyword" :successInvite="successInvite" @inviteClick="inviteClick" v-if="keyword !== ''"></search-content> </div> <!-- 协议弹出层 --> <pop-up @change="closeLayer" v-if="popuShow"> <h2 class="title">{{protocolTitle}}</h2> <div class="content" v-html="protocolCon"></div> <div class="confirmBtn" :class="{active:isActive}" @click="confirmProtocol">{{btntxt}}</div> <div class="popCloseCon" @click="closeActionClick"></div> </pop-up> <!-- 比例弹出层 --> <scale @change="closeScale" @send="sendAjaxClick" :number="scaleCount" :scaleBtn="scaleBtn" :scaleDesc="scaleDesc" v-show="isScale" :userId="userId"></scale> </div> </template> <script> import FastChoice from './components/fastChoice'; import PopUp from './components/PopUp'; import scale from './components/scale'; import SearchContent from './components/searchContent'; const pageSize=10; let t=''; export default { name: "Search", data() { return { placeholderStr: '搜一搜你想找的TA', keyword: '', list: [], timerKey: null, dataList:[],//列表数据 totalPage:1, popuShow:false,//协议弹出层 isScale:false,//比例弹出层 scaleValue:'',//分成比例 userId:'', isActive:true,//操作协议按钮灰色显示 sencond:5,//秒数 btntxt:'', //操作协议层按钮文字显示 scaleValue:'',//分成比例 scaleDesc:'',//比例弹窗描述 scaleBtn:'', scaleCount:'50%',//默认分成比例 successInvite: [],//默认未邀请 protocolTitle:'',//协议标题 protocolCon:'' //协议内容 }; }, components:{FastChoice,PopUp,scale, SearchContent}, watch: { keyword () { if (!this.keyword){ return; } } }, mounted() { this.protocolAjax(); }, methods: { //邀请 inviteClick (item) { //点击邀请过的不予操作 if(this.successInvite.indexOf(item.hwUserId) > -1 || item.inviteStatus){ return; } this.isScale = true; this.userId = item.hwUserId; this.scaleDesc = '邀请成功后你可获取该用户部分收益,选择双方都认可的分成比例可以提高邀请成功率哦~'; this.scaleBtn = '发送邀请'; this.scaleCount = '50%';//邀请比例统一为50% }, //点击发送邀请 sendAjaxClick (value){ this.scaleValue = value; this.popuShow = true; this.isScale = false; this.isActive = true; this.sencond = 5 ; this.timer(); }, //5s时间倒计时 timer() { if (this.sencond > 0) { this.btntxt="已阅读同意并确认邀请("+this.sencond+"s)"; this.sencond--; t=setTimeout(this.timer, 1000); } else{ this.isActive = false; this.sencond = 5; this.btntxt="已阅读同意并确认邀请"; } }, //已阅读同意并确认 confirmProtocol () { if(this.isActive){ return false; } this.sendAjax(); }, //发送邀请请求 sendAjax () { console.log(this.scaleValue); let dd = this.scaleValue.toString(); this.$request.post(_basePath + '/activity/page20191018/inviteArtist.html',{userId: this.userId,shareRate:this.scaleValue}).then((res) => { this.successInvite.push(this.userId) ; mui.toast("已发送邀请,对方接受后会通知你哦",2000); this.closeActionClick(); }).catch(() => {}) }, //关闭操作协议弹窗 closeActionClick() { this.popuShow = false; clearTimeout(t);//清除倒计时 }, //关闭分成比例弹窗 closeScale () { this.isScale = false; }, clear () { this.keyword = ""; this.$refs["input"].focus(); }, protocolAjax () { this.$request.post(_basePath + '/activity/page20191018/queryProtocol.html',{type:0}).then((res) => { this.protocolTitle = res.title; this.protocolCon = res.content; }).catch(() => {}) } }, }; </script> <style lang="scss" scoped> @import "search"; </style>
子组件处理:
<template> <div> <div ref="mescroll" class="mescroll"> <div class="search-content wrapper" ref="scroller" > <ul> <li class="item" v-for="(item,index) in dataList" :key="index"> <div class="personBlock" @click="openUserClick(item.userDetail.userId)"> <div class="showImg"> <img :src="item.userDetail.userThumUrl" /> <template v-if="item.userDetail.kolFlag"> <em v-if="item.userDetail.kolFlag" class="icon c_kol"></em> </template> <template v-else> <em class="icon c_company" v-if="item.userDetail.upSignType == '1'"></em> <em class="icon c_person" v-if="item.userDetail.upSignType == '0'"></em> </template> </div> <div class="showInfo"> <div class="name">{{item.userDetail.nickName}}</div> <div class="attentionCount"> {{item.userDetail.fansCount || 0}}人关注TA </div> </div> </div> <div class="sendBtn" :class="{active:item.userDetail.inviteStatus || (successInvite.indexOf(item.userDetail.hwUserId) > -1 ) }" @click="inviteClick(item.userDetail)"> <span v-if="item.userDetail.inviteStatus || successInvite.indexOf(item.userDetail.hwUserId) > -1">已邀请</span> <span v-else>邀请</span> </div> </li> </ul> </div> </div> <empty v-show="isEmpty"> <p class="note">纳尼,竟然找不到这个人…</p> </empty> </div> </template> <script> import MeScroll from 'mescroll.js'; import 'mescroll.js/mescroll.min.css'; import Empty from './empty'; const pageSize=10; export default { name: 'SearchContent', props: { searchName: { type: String, default: '' }, successInvite: { type: Array, default: [] } }, data() { return { dataList: [], mescroll: null, //mescroll实例对象 totalPage:1, isEmpty:false } }, components:{ Empty }, watch: { 'searchName' () { this.dataList = [];//要清空,不然有时候会出现上拉加载不了 this.searchName !== '' && this.mescroll.resetUpScroll(); } }, mounted () { console.log(this.searchName) this.mescroll = new MeScroll(this.$refs.mescroll, { //在mounted初始化mescroll,确保此处配置的ref有值 down:{isLock: true}, //下拉刷新的配置. (如果下拉刷新和上拉加载处理的逻辑是一样的,则down可不用写了) up: { callback: this.upCallback, // 以下是一些常用的配置,当然不写也可以的. page: { num: 0, //当前页 默认0,回调之前会加1; 即callback(page)会从1开始 size: 10, //每页数据条数,默认10 }, htmlLoading: '<p class="upwarp-progress mescroll-rotate"></p><p class="upwarp-tip">正在加载中..</p>', htmlNodata: '<p class="upwarp-nodata" style="height:.4rem">当当当~已经到底啦~</p>', noMoreSize: 1, //如果列表已无数据,可设置列表的总数量要大于5才显示无更多数据; isBounce: true, }, down:{ use:false }, }); }, methods: { //点击调起个人主页 openUserClick (item) { console.log(item) var userId = item; mui.openClient({"pageType": "userHome","userId":item}); }, //上拉回调 page = {num:1, size:10}; num:当前页 ,默认从1开始; size:每页数据条数,默认10 upCallback(page) { //联网请求 this.$request.post(_basePath + '/activity/page20191018/searchAll.html', {hintKey:this.searchName,searchType:91,pageNo:page.num,pageSize:page.size,actionSource:'07'}).then((response) => { if(response && response.resultList){ // 请求的列表数据 let result = response.resultList[0]; let arr = result.list; // 如果是第一页需手动置空列表 if (page.num === 1) this.dataList = [] // 把请求到的数据添加到列表 this.dataList = this.dataList.concat(arr) // 数据渲染成功后,隐藏下拉刷新的状态 this.totalPage = result.total % pageSize > 0 ? Math.floor(result.total / 10 + 1) : result.total / 10;//计算总页数超过就不loadMore this.$nextTick(() => { this.mescroll.endSuccess(arr.length); this.mescroll.endByPage(arr.length, this.totalPage) }) }else{ this.isEmpty = true; this.mescroll.endErr(); } }).catch(() => { this.mescroll.endErr(); }) }, inviteClick(item) { this.$emit('inviteClick',item); } } } </script> <style lang="scss" scoped> .mescroll { position: fixed; top: .9rem; bottom: 0; left:0; height: auto; } .search-content{ padding:0 .24rem; background: #121223; ul{ height:auto; .item{ display:flex; justify-content:space-between; align-items:center; width:100%; height:1.56rem; .personBlock{ display:flex; justify-content: flex-start; align-items: center; .showImg{ position:relative; width:1rem; height:1rem; margin-right:.16rem; border:.02rem solid #51516D; border-radius:50%; box-sizing: border-box; img{width:100%;height:100%;border-radius:50%} .icon{ position: absolute; bottom:0; right:0; width:.28rem; height:.28rem; background-image:url(); background-repeat:no-repeat; background-size:contain; &.c_company{background-image:url(../../images/c_company.png);} &.c_person{background-image:url(../../images/c_person.png);} &.c_kol{background-image:url(../../images/kol.png);} } } .showInfo{ .name{font-size:.3rem;color:#fff;font-weight:500;line-height:.42rem;text-align:left;} .attentionCount{font-size:.26rem;font-weight:400;color:#716D80;text-align:left;} } } .sendBtn{ width:1.44rem; height:.56rem; line-height:.56rem; background:#FF005E; border-radius:.28rem; color:#fff; text-align:center; &.active{background:#2C2B41;color:#fff} } } } } </style>
填坑处理:
1、用户未输入搜索关键词时,mescroll不能就直接初始话,要在用户输入的时候才能初始化,所以子组件就接受了父组件的keyword,并用
v-if="keyword !== ''"
来判断加载子组件的条件,然后子组件通过监听keyword的变化,重置mescroll:如下:
watch: { 'searchName' () { this.dataList = [];//要清空,不然有时候会出现上拉加载不了 this.searchName !== '' && this.mescroll.resetUpScroll(); } },
2、搜索完以后点击搜索输入框右边里的关闭按钮,发现其他列表不能滑动。解决方法:要加:isBounce: true,
ps:下面看下mescroll vue使用
github: https://github.com/mescroll/mescroll
最好按照官方文档来
开启初始化完毕之后自动执行上拉加载的回调,保证一进入页面,就去加载数据
上拉刷新的时候,或者tab切换的时候,先将数据置空
page 和 pageSize使用upOption中的,并且num默认为0
代码:
// html <mescroll-uni top="100" @down="downCallback" @up="upCallback" @init="mescrollInit" :up="upOption" :down="downOption"> //data: // 下拉刷新的常用配置 downOption: { use: true, // 是否启用下拉刷新; 默认true auto: false, // 是否在初始化完毕之后自动执行下拉刷新的回调; 默认true }, // 上拉加载的常用配置 upOption: { use: true, // 是否启用上拉加载; 默认true auto: true, // 是否在初始化完毕之后自动执行上拉加载的回调; 默认true textNoMore:'我是有底线的 >_<', page: { num:0, size: 4 } }, list:[], //methods: // 下拉回调 downCallback(mescroll){ mescroll.setPageNum(1) this.list = [] mescroll.resetUpScroll(); setTimeout(()=>{ console.log(666); // 隐藏下拉加载状态 mescroll.endErr() },1000) }, // 上拉回调 upCallback(mescroll){ setTimeout(()=>{ let pageNum = mescroll.num == 0 ? 1: mescroll.num; // 页码, 默认从1开始 let pageSize = mescroll.size; this.getPageList(pageNum, pageSize).then((res)=>{ mescroll.endSuccess(res) }) },1000) }
