Vue.js 表单

用 v-model 指令在表单控件元素上创建双向数据绑定

输入框

<div id="app" style="text-align: center">
    <p>info1:</p>
    <p>{{info1}}</p>
    <input type="text" v-model="info1" placeholder="请输入内容..." style="width: 333px">
    <hr>
    <p>info2:</p>
    <p style="white-space: pre">{{info2}}</p>
    <textarea v-model="info2" placeholder="输入多行文本..." style="width: 333px;height: 222px"></textarea>
</div>
<script type="text/javascript">
    new Vue({
        el:'#app',
        data:{
            info1:'LeDao的博客:http://www.zoutl.cn',
            info2:'LeDao的博客:\r\nhttp://www.zoutl.cn'
        }
    })
</script>

单选按钮

<div id="app">
    <input type="radio" id="Edge" value="Edge" v-model="picked">
    <label for="Edge">Edge</label>
    <input type="radio" id="Chrome" value="Chrome" v-model="picked">
    <label for="Chrome">Chrome</label>
    <p>当前选中:<span style="color: red">{{picked}}</span></p>
</div>
<script type="text/javascript">
    new Vue({
        el: '#app',
        data: {
            picked: 'Edge'
        }
    })
</script>

复选框

复选框如果是一个为逻辑值，如果是多个则绑定到同一个数组

<div id="app" style="margin-left: 200px">
    <p>单个复选框:</p>
    <input type="checkbox" id="flag" v-model="checkValue">
    <label for="flag">{{checkValue ? '是' : '否'}}</label>
    <p>多个复选框:</p>
    <input type="checkbox" id="Edge" value="Edge" v-model="browers">
    <label for="Edge">Edge</label>
    <input type="checkbox" id="Chrome" value="Chrome" v-model="browers">
    <label for="Chrome">Chrome</label>
    <input type="checkbox" id="Firefox" value="Firefox" v-model="browers">
    <label for="Firefox">Firefox</label>
    <p>选择的浏览器:<span style="color: red">{{browers}}</span></p>
</div>
<script type="text/javascript">
    new Vue({
        el: '#app',
        data: {
            checkValue: true,
            browers: []
        }
    })
</script>

select列表

<div id="app" style="margin-left: 222px">
    <p>选择的浏览器是:<span style="color: red">{{mySelect}}</span></p>
    <select v-model="mySelect" name="browers">
        <option value="">选择一个浏览器</option>
        <option value="Edge">Edge</option>
        <option value="Chrome">Chrome</option>
        <option value="Firefox">Firefox</option>
    </select>
</div>
<script type="text/javascript">
    new Vue({
        el: '#app',
        data: {
            mySelect: ''
        }
    })
</script>
