vue的mescroll搜索运用以及各种填坑处理

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：

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
