vue2 radio单选

<span v-for="item in radioData" :key="item.value">
<input type="radio" @click="chcekRadio($event)" name="abutmentVal" v-model="myData.abutmentVal" :id="'Abutment'+ item.id" :value="item.id" />
<label :for="'Abutment'+ item.id" :value="item.id">{{ item.name }}</label>
</span>
 
//vue中radio单选框单击取消选中状态
    chcekRadio ($event) {
      let _this = this;
      let objVal = _this.myData[$event.target.name];
      window.setTimeout(() => {
        if (!!objVal && objVal == $event.target.value) {
          $event.target.checked = false
          _this.myData[$event.target.name] = ''
        }
      }, 0);
    },
 
如何获取radio的选中值 、选中状态
方法1 设置v-model
<!DOCTYPE html> 
<html> 
<head> 
    <meta charset="utf-8"> 
    <title>test</title> 
    <script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script> 
</head> 
<body> 
    <div id='app'>
      <input type="radio" name="test" v-for="(item,index) in list" :value="item.value" v-model="checkedValue">
      <button @click="test">获取选中的值</button>
    </div>
<script>
var vm = new Vue({
  el:'#app',
  data(){
    return{
      checkedValue:'',
      list:[{value:1},{value:2},{value:3}]
    }
  },
  methods:{
    test(){
      console.log('被选中的值为:'+this.checkedValue)
    }
  }
});
</script>
</body> 
</html>
 
 
方法2 如果不想每次点击都判断，那就提供一个思路，定义一个radio数组list，每项设置一个isCheck标识，循环该数组渲染radio，点击按钮时再统一去判断
<!DOCTYPE html> 
<html> 
<head> 
    <meta charset="utf-8"> 
    <title>test</title> 
    <script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script> 
</head> 
<body> 
    <div id='app'>
      <input type="radio" name="test" v-for="(item,index) in list" :value="item.value" :checked="item.isCheck" @change="changeInput(index)">
      <button @click="test">获取选中的值</button>
    </div>
<script>
var vm = new Vue({
  el:'#app',
  data(){
    return{
      list:[{value:1,isCheck:false},{value:2,isCheck:false},{value:3,isCheck:false}]
    }
  },
  methods:{
    changeInput(index){
      this.list.map((v,i)=>{
        if(i==index){
          v.isCheck = true
        }else{
          v.isCheck = false
        }
      })
    },
    test(){
      this.list.map((v,i)=>{
        if(v.isCheck){
          console.log('被选中的值为:'+v.value)
        }
      })
    }
  }
});
</script>
</body> 
</html>
