Im Folgenden werde ich Ihnen ein Beispiel für Vue-Aktualisierung und Tab-Wechsel vorstellen, das einen guten Referenzwert hat und ich hoffe, dass es für alle hilfreich ist.
Schreiben Sie zunächst eine Unterkomponente namens pull, die den aktualisierten Inhalt enthält (Sie können sie am Ende des Beispiels sehen).

Das Folgende ist die Unterkomponente namens pull.

Ein Beispiel für Tab
<template> <p class="mypage"> <p class="fbjbox"> <p class="fbjbox1"> <tab ref="tab" :list="['一级合伙人'+count,'二级合伙人']" width="50%" @change="tabchange" /> </p> <p class="fbjbox2"> <template v-if="list!=null&&tab==0"> <h4 >一级合伙人总数{{count}}人</h4> <ul class="mui-table-view clear"> <li class="mui-table-view-cell mui-media" v-for="item in list"> <img class="mui-media-object mui-pull-left circle" v-bind:src="item.head_url" /> <p class="mui-media-body"> {{item.vname}} <p class='mui-ellipsis'>{{item.identity}}</p> </p> </li> </ul> </template> <template v-if="list!=null&&tab==1"> <h4 >二级合伙人总数{{count}}人</h4> <ul class="mui-table-view clear"> <li class="mui-table-view-cell mui-media" v-for="item,index in list"> <p class="mui-media-body" v-cloak> {{type(index)}}人数<p class="mui-pull-right">{{item}}</p> </p> </li> </ul> </template> <!--<template v-if="list==null"> <p class=" mui-text-center" style="padding: 50px;"> <span class="mui-spinner"></span> </p> </template>--> <template v-if="list==[]"> <p>暂无下线</p> </template> </p> </p> </p> </template> <style scoped=""> p{color:#807E7E} .circle{margin-top:0px} .mypage{height:100%;} .mui-table-view .mui-media-object { line-height: 45px; max-width: 45px; height: 45px; } </style> <script> import tab from "../public/tab" import pull from "../public/pull" export default { mounted() { this.changemes(); }, components: {tab,pull}, data() { return { tab:0, count:0, list: [] } }, computed:{ cmd:function(){ switch(this.tab){ case 0: return "Member/oneLevel"; case 1: return "Member/twoLevel"; } } }, methods: { type(num){ switch (~~num) { case 1: return "游客"; case 2: return "用户"; case 3: return "粉丝"; case 4: return "美人"; case 5: return "卖手"; case 6: return "合伙人"; case 7: return "加盟商"; } return "未知"; }, tabchange({index, data}) { this.tab = index; }, changemes(){ this.list=null; this.$api(this.cmd).then(list => { this.count=list.count; this.list=list.list; }); } }, watch:{ tab:function(){ this.changemes(); } } } </script>
Das Obige habe ich für alle zusammengestellt hilfreich für alle in der Zukunft.
