vue循环中点击选中再点击取消(单选)的实现

没有展开时

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 @click='tocomment(index)'><i :class='{showcolor:currentTab==index}'></i>10</span> </div> </div> <div :class='{’showcomment’:currentTab==index}'> <div class='textarea_com'> <textarea placeholder='你来谈谈？' v-on:input='change' v-model='comment'></textarea> <button :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);' : >{{item}}</i></div>

2.

.padding .relWarp .relFacility .relFacilityTitcon { /* border: 1px solid red; */ /* line-height: 20px; */ padding: 0 .24rem; font-size :10px; } .padding .relWarp .relFacility .relFacilityTitcon i {/* height:20px; */ display: inline-block; /* margin: 0 5px; */ height: 20px; line-height: 20px; padding: 0 .16rem; /* width: auto; */ font-size: 10px; color: #97979f; border-radius: 5px; border: 1px solid #97979f; margin-right: 10px; margin-top: 10px; font-style: normal; /* padding:1px 7px; */ /* display: inline-block; */ } .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);} },
