vue：复选框，单选框绑定总结

复选框

单个复选框，绑定到布尔值：

<input type="checkbox" id="checkbox" v-model="checked">
<label for="checkbox">{{ checked }}label>

多个复选框，绑定到同一个数组：

<div id='example-3'>
  <input type="checkbox" id="jack" value="Jack" v-model="checkedNames">
  <label for="jack">Jacklabel>
  <input type="checkbox" id="john" value="John" v-model="checkedNames">
  <label for="john">Johnlabel>
  <input type="checkbox" id="mike" value="Mike" v-model="checkedNames">
  <label for="mike">Mikelabel>
  <br>
  <span>Checked names: {{ checkedNames }}span>
div>
new Vue({
  el: '#example-3',
  data: {
    checkedNames: []
  }
})

单选框

<div id="example-4">
  <input type="radio" id="one" value="One" v-model="picked">
  <label for="one">Onelabel>
  <br>
  <input type="radio" id="two" value="Two" v-model="picked">
  <label for="two">Twolabel>
  <br>
  <span>Picked: {{ picked }}span>
div>
new Vue({
  el: '#example-4',
  data: {
    picked: ''
  }
})
