Vue表单控件绑定

v-model 指令在表单控件元素上创建双向数据绑定

文本

<div id="example-1" class="demo">
  <input v-model="message" placeholder="edit me">
  <p>Message is: {{ message }}</p>
</div>
<script>
new Vue({
  el: '#example-1',
  data: {
    message: ''
  }
})
</script>

多行文本

<div id="example-textarea" class="demo">
  <span>Multiline message is:</span>
  <p style="white-space: pre">{{ message }}</p>
  <br>
  <textarea v-model="message" placeholder="add multiple lines"></textarea>
</div>
<script>
new Vue({
  el: '#example-textarea',
  data: {
    message: ''
  }
})
</script>

复选框

单个勾选框

<div id="example-2" class="demo">
  <input type="checkbox" id="checkbox" v-model="checked">
  <label for="checkbox">{{ checked }}</label>
</div>
<script>
new Vue({
  el: '#example-2',
  data: {
    checked: false
  }
})
</script>

多个勾选框

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

单选按钮

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

选择列表

<div id="example-6" class="demo">
  <select v-model="selected" multiple style="width: 50px">
    <option>A</option>
    <option>B</option>
    <option>C</option>
  </select>
  <br>
  <span>Selected: {{ selected }}</span>
</div>
<script>
new Vue({
  el: '#example-6',
  data: {
    selected: []
  }
})
</script>

多选列表（绑定到一个数组）

<div id="example-6" class="demo">
  <select v-model="selected" multiple style="width: 50px">
    <option>A</option>
    <option>B</option>
    <option>C</option>
  </select>
  <br>
  <span>Selected: {{ selected }}</span>
</div>
<script>
new Vue({
  el: '#example-6',
  data: {
    selected: []
  }
})
</script>

动态选项，用 v-for 渲染

<div id="example-7" class="demo">
  <select v-model="selected">
    <option v-for="option in options" v-bind:value="option.value">
      {{ option.text }}
    </option>
  </select>
  <span>Selected: {{ selected }}</span>
</div>
<script>
new Vue({
  el: '#example-7',
  data: {
    selected: 'A',
    options: [
      { text: 'One', value: 'A' },
      { text: 'Two', value: 'B' },
      { text: 'Three', value: 'C' }
    ]
  }
})
</script>
