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);
          }
        }
      },
