使用HTML5数据表完成自动完成

DATALIST元素获取ID属性并包含许多OPTION元素,就像SELECT元素一样:

<p>Type php for view example</p>
<input name="resources" list="resources" />

<datalist id="resources">
 <option value="php">
 <option value="php 4">
 <option value="php 5">
 <option value="css">
 <option value="css3">
</datalist>

表单验证与必填

必需属性将任何输入/文本区标记为在提交表单之前需要具有值。

<form >
 <fieldset>
 <legend>Required Example</legend>
 <div>
 <label for="name">Name (required):</label>
 <input type="text" id="name" name="name" required="true">
 </div>
 <div>
 <label for="email">Email (required):</label>
 <input type="email" id="email" name="email" required="true">
 </div>
 <div>
 <label>Website:</label>
 <input type="url" id="website" name="website" required="true">
 </div>
 <input type="submit" value="Submit"/>
 </fieldset>
</form>
