【猿说VUE】Vue基础之表单介绍

10 VUE基础：表单输入

可以用v-model指令在表单 、</code> 及 <code><select></code> 元素上创建双向数据绑定，<code>v-model</code>会根据控件类型自动选取正确的方法来更新元素。<code>v-model</code>主要负责监听用户的输入事件以更新数据，并对一些极端场景进行一些特殊处理。</p> <p><code>v-model</code>会忽略所有表单元素的 <code>value</code>、<code>checked</code>、<code>selected</code> 等属性的初始值而总是将<code>Vue</code>实例的数据作为数据来源，所以需要通过JavaScript在组件的<code>data</code>选项中声明初始值。</p> <p><code>v-model</code>在内部为不同的输入元素使用不同的属性并抛出不同的事件：</p> <ul> <li><code>text</code> 和 <code>textarea</code> 元素使用 <code>value</code> 属性和 <code>input</code> 事件；</li> <li><code>checkbox</code> 和 <code>radio</code> 使用 <code>checked</code> 属性和 <code>change</code> 事件；</li> <li><code>select</code> 字段将 <code>value</code> 作为 <code>prop</code> 并将 <code>change</code> 作为事件。</li> </ul> <h3>10.1

事件触发后将输入框的值与数据进行同步，可以添加 <code>lazy</code> 修饰符，从而转为在 <code>change</code> 事件之后进行同步。</p> <pre><code><!-- 在“change”时而非“input”时更新 --> <input v-model.lazy="msg"> </code></pre> <p>[<code>.number</code>]：自动将用户的输入值转为数值类型，可以给 <code>v-model</code> 添加 <code>number</code> 修饰符。</p> <pre><code><input v-model.number="age" type="number"> </code></pre> <p>这通常很有用，因为即使在 <code>type="number"</code> 时，HTML输入元素的值也总会返回字符串。如果这个值无法被 <code>parseFloat()</code> 解析，则会返回原始的值。</p> <p>[<code>.trim</code>]：如果要自动过滤用户输入的首尾空白字符，可以给 <code>v-model</code> 添加 <code>trim</code> 修饰符：</p>
