vue点击标签切换选中及互相排斥操作
单身和已婚不能同时选中,不了解保险和已了解保险不能同时选中。
同时各个标签点击可以取消选择
//html <li> <span class="fill-title">与我相关</span> <div> <van-button v-for="(item, index) in myself" :key="index" @click="checkButton('myself', item.id)" :class="item.isFlag ? 'current' : ''" >{{item.title}}</van-button> </div> </li> <li> <span class="fill-title">标签</span> <div> <van-button v-for="item in biaoqian" :key="item.id" @click="checkButton('tag', item.id)" :class="item.isFlag ? 'current' : ''" >{{item.title}}</van-button> </div> </li>
数据
myself: [ { id: 1,title: "亲属", isFlag: false }, {id: 2,title: "同乡",isFlag: false}, {id: 3, title: "同学",isFlag: false }, {id: 4,title: "同事", isFlag: false},], biaoqian: [ {id: 1, title: "已婚",type: 1,isFlag: false }, {id: 2,title: "单身",type: 1,isFlag: false }, {id: 3,title: "有娃",isFlag: false }, {id: 4,title: "有房", isFlag: false }, {id: 5,title: "有车",isFlag: false}, {id: 6,title: "不了解保险",isFlag: false,type: 2}, {id: 7,title: "已了解保险",isFlag: false,type: 2} ],
js
//标签只能选中一个 filterData(arr = [], index) { let val = ""; arr.forEach(item => { if (item.id == index) { item.isFlag = !item.isFlag; val = item.isFlag ? item.title : ""; } else { item.isFlag = false; } }); return val; }, checkButton(val, index) { if (val === "tag") { let data = []; this.biaoqian.forEach(item => { if (item.id == index) { // a 记录当前标签状态是否选中,为了取消标签状态 let a = item.isFlag; item.isFlag = !item.isFlag; if (item.type) { this.biaoqian.forEach(e => { if ((e.type == 1 && index < 3) || (e.type == 2 && index > 5)) { //先把同一个类型的标签都置为false e.isFlag = false; if (e.id == index) { e.isFlag = a ? false : !e.isFlag; } } }); } } }); let arr = this.biaoqian.filter(item => { return item.isFlag; }); arr.forEach(item => { data.push(item.title); }); this.personItem.labelList = data; } else if (val === "sex") { this.personItem.sex = this.filterData(this.sexArr, index); } else { this.personItem.relation = this.filterData(this.myself, index); } }
补充知识:vue选中与取消简单实现
我就废话不多说了,大家还是直接看代码吧~
<li v-for="(item,index) in assign" :key="index" @click="selected(item)" :class="{'active':item.isShow}"> selected(item) { if (!item.isShow) { item.isShow = true; this.selectedList.push(item.id) } else { item.isShow = false; let index = this.selectedList.indexOf(item.id); if (index > -1) { this.selectedList.splice(index, 1); } } },
以上这篇vue点击标签切换选中及互相排斥操作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我们。
