jqueryValidator自定义校验规则的一种方式（不覆盖源码）
1.封装自定义验证方法-validate-methods.js

} return false; }
2.测试-validate-methods.jsp(引入自定义的validate-methods.js)（在js代码中校验）
<%@ 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"> <html> <head> <base href="<%=basePath%>"> <title>jQuery Validate扩展验证方法</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <script type="text/javascript" src="<%=request.getContextPath()%>/validate/jquery-1.6.2.min.js"></script> <script type="text/javascript" src="<%=request.getContextPath()%>/validate/jquery.validate.min.js"></script> <script type="text/javascript" src="<%=request.getContextPath()%>/validate/jquery.metadata.min.js"></script> <script type="text/javascript" src="<%=request.getContextPath()%>/validate/validate-methods.js"></script> <script type="text/javascript" src="<%=request.getContextPath()%>/validate/messages_zh.js"></script> <script type="text/javascript"> $(function(){ var validate = $("#myform").validate({ debug: true, //调试模式取消submit的默认提交功能 submitHandler: function(form){ //表单提交句柄,为一回调函数，带一个参数：form alert("提交表单"); form.submit(); //提交表单 }, rules:{ zero:{ //isIntEqZero:true //isFloat:true //isInteger:true //isNumber:true //isMobile:true //isPhone:true //isTel:true //isIdCardNo:true //isRightfulString:true isContainsSpecialChar:true } }, //如果验证控件没有message，将调用默认的信息 messages:{ zero:{ //isIntEqZero:"请输入0" //isFloat:"请输入浮点数" //isInteger:"请输入整数" } } }); }); </script> </head> <body> <form id="myform" method="post" action=""> <p> <label for="zero">输入框：</label> <!-- id和name最好同时写上 --> <input id="zero" name="zero" /> </p> <p> <input class="submit" type="submit" value="验证" /> </p> </form> </body> </html>
或者这样写(在标签中校验)：
<body> <form id="myform" method="post" action=""> <p> <label for="zero">输入框：</label> <!-- id和name最好同时写上 --> <input id="zero" name="zero" /> </p> <p> <input class="submit" type="submit" value="验证" data-rule-isIntEqZero="true" /> </p> </form> </body>
