iview中单选框绑定点击事件触发两次解决

    <span @click="doraEntity($event)">
      <Radio-group v-model="button1"
                   type="button">
        <Radio label="点"></Radio>
        <Radio label="线"></Radio>
        <Radio label="面"></Radio>
      </Radio-group>
    </span>

 doraEntity(e) {
      if (e.target.type === 'radio') return

      console.log(e)
      console.log(1)
      if (this.button1 === '点') {
        console.log('dian')
      }
    },

原因，两次一次是click 一次是radio，禁用一次即可
