在父组件中,根据后台给的数据(数组),v-for生成子组件
<div class="exist"> <existProject :itemprop="item" v-for="(item, index) in getData" :key="index" :index="index" @click="sendIdTogetData(index)" v-show="true"></existProject> </div>
<template> <!-- <transition name="el-zoom-in-center"> --> <div class="existProjectBox" v-show="show2"> <div class="existContentBox"> <div class="existContent"> <div class="existTitle">{{itemprop.title}}</div> <div class="stateBox"> <span class="state">{{ status_tit }}</span> <span class="number" v-if="itemprop.status==2">收集份数:{{itemprop.asyncCount}}份</span> </div> <div class="tiemBox"> {{createtime}} </div> </div> </div> <div class="existButton"> <li v-if="itemprop.status==0" @click="turnEdit(itemprop.qid)"> <i class="icon icon-edit"></i> <span>编辑</span> </li> <li v-if="itemprop.status==0" @click="turnSend(itemprop.qid)"> <i class="icon icon-send"></i> <span>发布</span> </li> <li v-if="itemprop.status==2 "> <i class="icon icon-data"></i> <span>数据</span> </li> <!-- <li v-if="itemprop.status==2 "> <i class="icon icon-data"></i> <span>暂停</span> </li> <li v-if="itemprop.status==2 "> <i class="icon icon-data"></i> <span>终止</span> </li> --> <li @click="delItem(itemprop.qid)"> <i class="icon icon-other"></i> <span>删除</span> </li> </div> </div> <!-- </transition> --> </template>
<script> import axios from 'axios' export default { data(){w return{ createtime:'', status_tit:'', show2:true } }, props:['itemprop'], methods:{ turnEdit(id){ debugger; console.log(id) axios.defaults.headers.common['token'] = JSON.parse(window.localStorage.getItem('token')) axios.get('/question/'+id) .then(response => { console.log(response); var obj = response.data.data; var contents = obj.contents; for(let i = 0; i < contents.length; i++){ obj.contents[i].component = this.$options.methods.initType(obj.contents[i].type) } console.log(obj) window.localStorage.setItem('workInfoList', JSON.stringify(obj)); this.$router.push({ path: '/edit', query: { id: id } }) window.location.reload() }) .catch(error => { console.log(error) }) }, turnSend(id){ debugger; console.log(id) axios.defaults.headers.common['token'] = JSON.parse(window.localStorage.getItem('token')) axios.get('/question/'+id) .then(response => { console.log(response); var obj = response.data.data; console.log(obj) window.localStorage.setItem('workInfoList', JSON.stringify(obj)); this.$router.push({ path: '/sendProject', query: { id: id } }) window.location.reload() }) .catch(error => { console.log(error) }) }, delItem(id){ this.$confirm('此操作将删除该文件进入草稿箱, 是否继续?', '提示', { confirmButtonText: '确定', cancelButtonText: '取消', type: 'warning' }) .then(() => { axios.defaults.headers.common['token'] = JSON.parse(window.localStorage.getItem('token')) axios.delete('/question/'+id) .then(response => { console.log(response) // this.show2 = false this.$parent.getPage(); }) }) .catch(error => { console.log(error) }) }, initType(str){ switch(str){ case 1:return 'Radio'; case 2:return 'check'; case 3:return 'gapFill'; case 4:return 'level'; case 5:return 'photoInput'; case 6:return 'Rate'; case 7:return 'remark'; case 8:return 'selectChoice'; case 9:return 'sort'; case 10:return 'tableNumber'; case 11:return 'temp'; } }, }, mounted(){ // console.log(this.itemprop.createTime) var transformTime = new Date(this.itemprop.createTime) this.createtime = transformTime.toLocaleString(); console.log(this.createtime) }, } </script>
因为有多条数据,所以有分页处理,在第一页中数据显示正常,但是在获得第二页数据并赋值给父组件的data后,子组件的信息保留的还是第一页的信息
watch:{ itemprop:{ handler(n,o){ console.log(this.itemprop); var status = this.itemprop.status; var showCondition = this.itemprop.showCondition; // debugger; this.status_tit = (function(status,showCondition) { if(status==0) { return '未发布'; } if(status==2 && showCondition==1) { // 已发布 return '收集中'; } if(status==2 &&showCondition==0) { // 暂停 return '已暂停'; } if(status==2 &&showCondition==-1) { // 终止 return '已终止'; } if(status==2 &&showCondition==2) { // 问卷发布结束 return '已结束'; } })(status,showCondition) }, deep:true, immediate:true, } }
watch可以监听子组件的数据变化,数组或者对象要用深度监听,字符串什么的不用深度监听,这样就可以在分页切换数据后,就不会保留原有的信息,而是新的信息了
这是Element-UI的一个bug,解决方案是从el-table中增加一个row-key属性,并为row-key设置一个能唯一标识的字段名。
1.这个可以是数据库的id字段
<el-table row-key="_id" ></el-table>
2.给table增加一个随机数的key
<el-table :key="Math.random()" ></el-table>
