在用户注册的时候,常常用户点击文字就需要将光标聚焦到对应的表单上面,这个是怎么实现的呢?就是下面我要介绍的<label>标签的for属性
定义:for 属性规定 label 与哪个表单元素绑定
- <!--
- 显式的联系:
- <label for="SSN">Social Security Number:</label>
- <input type="text" name="SocSecNum" id="SSn" />
- 隐式的联系:
- <label>Date of Birth: <input type="text" name="DofB" /></label>
- -->
下面是例子:
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
- <title>无标题文档</title>
- </head>
- <body>
- <table>
- <tr>
- <td><label for="username">用户名:</label></td>
