<input type="checkbox" id="spam_phone" value="phone" name="spam[]" />
<input type="checkbox" id="spam_mail" value="mail" name="spam[]" />
</p>
<p>
<label for="confirm_password">城市：</label>
<select id="jungle" name="jungle" title="Please select something!" class="{required:true}">
<option value=""></option>
<option value="1">厦门</option>
<option value="2">泉州</option>
<option value="3">Oi</option>
</select>
</p>
<p>
<input class="submit" type="submit" value="立即注册" />
</p>
</form>
</body>
</html>
使用class=”{}”的方式，必须引入包：jquery.metadata.js；
可以使用如下的方法，修改提示内容：class=”{required:true,minlength:5,messages:{required:’请输入内容’}}”；
在使用equalTo关键字时，后面的内容必须加上引号，如下代码：class=”{required:true,minlength:5,equalTo:’#password’}”。
2、将校验规则写到js代码中
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":"
+ request.getServerPort() + path + "/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
