点击展开之后

<div class="flashread_item_box_time"> <span class="moment_time">9分钟前</span> <div class="flashread_item_box_zan"> <span class="flashread_item_box_item"><i class="iconfont icon-changyongtubiao-mianxing-"></i>10</span> <span class="flashread_item_box_item" @click="tocomment(index)"><i class="iconfont icon-pinglun" :class="{showcolor:currentTab==index}"></i>10</span> </div> </div> <div class="comment_textareabox" :class="{'showcomment':currentTab==index}"> <div class="textarea_com"> <textarea placeholder="你来谈谈？" class="comment_textarea" v-on:input="change" v-model="comment"></textarea> <button class="btn_comment" :class="{'showcolor':showcombtn}">发表</button> </div> </div>data(){ return{ currentTab:-1, flashreadlists:[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15], showcombtn:false, comment:'' } }, methods:{ change(){ if(this.comment.length>=1){ this.showcombtn=true }else{ this.showcombtn=false } }, tocomment(index){ if(index!=this.currentTab){ this.currentTab = index; }else{ this.currentTab = -1; } } }

补充知识：vue 循环多个标签，点击标签变色，再点击取消，可以同时点击多个

效果如下：

1.

<div class="relFacilityTitcon"> <i v-for="(item,index) in facilityList" :key="index" @click="changeSpan(index);" :class="{'bgcolor':spanIndex.indexOf(index)>-1}" >{{item}}</i></div>

2.

.padding .relWarp .relFacility .relFacilityTitcon { padding: 0 .24rem; font-size :10px; } .padding .relWarp .relFacility .relFacilityTitcon i { display: inline-block; height: 20px; line-height: 20px; padding: 0 .16rem; font-size: 10px; color: #97979f; border-radius: 5px; border: 1px solid #97979f; margin-right: 10px; margin-top: 10px; font-style: normal; } .padding .relWarp .relFacility .relFacilityTitcon .bgcolor { border: 1px solid orange; color: orange; } .padding .relWarp .relFacility .relFacilityTitcon i:last-child { margin-right: 0; }

3.

methods: { changeSpan(index){ let arrIndex = this.spanIndex.indexOf(index); // console.log(arrIndex); if(arrIndex>-1){ this.spanIndex.splice(arrIndex,1); }else{ this.spanIndex.push(index); } },

以上这篇vue循环中点击选中再点击取消(单选)的实现就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
