页面展示:
实现效果:点击实现列表内容的展开、折叠。
<div class="invoice-list" v-for="(item,index) in invoiceData" :key="index"> <div class="images"><img src="../../../../../static/images/invoice_pu.png" v-if="item.invoiceType == '0'"><img src="../../../../../static/images/invoice_zhuan.png" v-else-if="item.invoiceType == '1'"></div> <div class="text"> <h3 v-if="item.invoiceType == '0'">增值税普通发票</h3> <h3 v-else-if="item.invoiceType == '1'">增值税专用发票</h3> <p><span>企业名称:</span>{{item.enterpriseName}}</p> <p><span>税号:</span>{{item.dutyParagraph}}</p> <transition name="fade"> <div class="zhuanInfo" v-if="item.mark == true"> <p><span>注册地址:</span>{{item.address}}</p> <p><span>联系电话:</span>{{item.contactNumber}}</p> <p><span>开户银行:</span>{{item.accountOpeningBank}}</p> <p><span>银行账号:</span>{{item.bankAccount }}</p> </div> </transition> <div class="zhuanMark" v-if="item.invoiceType == '1'"> <p class="hideMark"> <img src="../../../../../static/images/arrow_bottom.png" v-if="item.mark == false" @click="clickZhuanMark(index,$event)"> <img src="../../../../../static/images/arrow_top.png" v-else @click="clickZhuanMark(index,$event)"> </p> </div> <div class="list-radio"><input type="radio" value="" name="selectContact" @change="getInvoiceId(item.invoiceId)" /></div> </div> </div>v-for渲染出列表,在执行列表折叠展开时"clickZhuanMark" JS如下:
clickZhuanMark(val,event){ this.invoiceData[val].mark = !this.invoiceData[val].mark; },可是实际并没有如设想的那样实现效果,之后修改代码:
添加this.$forceUpdate();进行强制渲染,效果实现。搜索资料得出结果:因为数据层次太多,render函数没有自动更新,需手动强制刷新。
