一、以往的校验都是自己写正则表达式校验，本篇讲的是通过MVC自带的jquery文件进行校验
实现步骤：1. 在webform页面中引入两个jquery文件，10,11行的代码。
1 <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<Userinfo>" %> 2 <%@ Import Namespace="MvcApplication1.Models" %> 3 4 <!DOCTYPE html> 5 6 <html> 7 <head runat="server"> 8 <meta name="viewport" content="width=device-width" /> 9 <title>ShowDetail</title> 10 <script src="../../Scripts/jquery-1.8.2.min.js"></script> 11 <script src="../../Scripts/jquery.validate.js"></script> 12 </head> 13 <body> 14 15 </body> 16 </html>
2. 在head中添加如下代码：
备注：ready方法指用于在当前文档结构载入完毕后立即执行指定的函数。该函数的作用相当于window.onload事件。
1 $().ready(function() { 2 // 在键盘按下并释放及提交后验证提交表单 3 $("#signupForm").validate({ 4 rules: { //规则 5 firstname: "required", 6 lastname: "required", 7 username: { 8 required: true, 9 minlength: 2 10 }, 11 password: { 12 required: true, 13 minlength: 5 14 }, 15 confirm_password: { 16 required: true, 17 minlength: 5, 18 equalTo: "#password" //指fonfirm_password和#password进行对比 19 }, 20 email: { 21 required: true, 22 email: true 23 }, 24 topic: { 25 required: "#newsletter:checked", 26 minlength: 2 27 }, 28 agree: "required" 29 }, 30 messages: { //消息 31 firstname: "请输入您的名字", 32 lastname: "请输入您的姓氏", 33 username: { 34 required: "请输入用户名", 35 minlength: "用户名必需由两个字母组成" 36 }, 37 password: { 38 required: "请输入密码", 39 minlength: "密码长度不能小于 5 个字母" 40 }, 41 confirm_password: { 42 required: "请输入密码", 43 minlength: "密码长度不能小于 5 个字母", 44 equalTo: "两次密码输入不一致" 45 }, 46 email: "请输入一个正确的邮箱", 47 agree: "请接受我们的声明", 48 topic: "请选择两个主题" 49 } 50 }) 51 });
二、基础介绍
JQuery Validate使用总结： 一、导入js库 <script src="../js/jquery.js" type="text/javascript"></script> <script src="../js/jquery.validate.js" type="text/javascript"></script> 二、默认校验规则 (1)required:true 必输字段 (2)remote:"check.php" 使用ajax方法调用check.php验证输入值 (3)email:true 必须输入正确格式的电子邮件 (4)url:true 必须输入正确格式的网址 (5)date:true 必须输入正确格式的日期 日期校验ie6出错，慎用 (6)dateISO:true 必须输入正确格式的日期(ISO)，例如：2009-06-23，1998/01/22 只验证格式，不验证有效性 (7)number:true 必须输入合法的数字(负数，小数) (8)digits:true 必须输入整数 (9)creditcard: 必须输入合法的信用卡号 (10)equalTo:"#field" 输入值必须和#field相同 (11)accept: 输入拥有合法后缀名的字符串（上传文件的后缀） (12)maxlength:5 输入长度最多是5的字符串(汉字算一个字符) (13)minlength:10 输入长度最小是10的字符串(汉字算一个字符) (14)rangelength:[5,10] 输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符) (15)range:[5,10] 输入值必须介于 5 和 10 之间 (16)max:5 输入值不能大于5 (17)min:10 输入值不能小于10 三、默认的提示 messages: { required: "This field is required.", remote: "Please fix this field.", email: "Please enter a valid email address.", url: "Please enter a valid URL.", date: "Please enter a valid date.", dateISO: "Please enter a valid date (ISO).", dateDE: "Bitte geben Sie ein g眉ltiges Datum ein.", number: "Please enter a valid number.", numberDE: "Bitte geben Sie eine Nummer ein.", digits: "Please enter only digits", creditcard: "Please enter a valid credit card number.", equalTo: "Please enter the same value again.", accept: "Please enter a value with a valid extension.", maxlength: $.validator.format("Please enter no more than {0} characters."), minlength: $.validator.format("Please enter at least {0} characters."), rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."), range: $.validator.format("Please enter a value between {0} and {1}."), max: $.validator.format("Please enter a value less than or equal to {0}."), min: $.validator.format("Please enter a value greater than or equal to {0}.") }, 如需要修改，可在js代码中加入： jQuery.extend(jQuery.validator.messages, { required: "必选字段", remote: "请修正该字段", email: "请输入正确格式的电子邮件", url: "请输入合法的网址", date: "请输入合法的日期", dateISO: "请输入合法的日期 (ISO).", number: "请输入合法的数字", digits: "只能输入整数", creditcard: "请输入合法的信用卡号", equalTo: "请再次输入相同的值", accept: "请输入拥有合法后缀名的字符串", maxlength: jQuery.validator.format("请输入一个 长度最多是 {0} 的字符串"), minlength: jQuery.validator.format("请输入一个 长度最少是 {0} 的字符串"), rangelength: jQuery.validator.format("请输入 一个长度介于 {0} 和 {1} 之间的字符串"), range: jQuery.validator.format("请输入一个介于 {0} 和 {1} 之间的值"), max: jQuery.validator.format("请输入一个最大为{0} 的值"), min: jQuery.validator.format("请输入一个最小为{0} 的值") }); 推荐做法，将此文件放入messages_cn.js中，在页面中引入 <script src="../js/messages_cn.js" type="text/javascript"></script> 四、使用方式1.将校验规则写到控件中 <script src="../js/jquery.js" type="text/javascript"></script> <script src="../js/jquery.validate.js" type="text/javascript"></script> <script src="./js/jquery.metadata.js" type="text/javascript"></script> $().ready(function() { $("#signupForm").validate(); }); <form id="signupForm" method="get" action=""> <p> <label for="firstname">Firstname</label> <input id="firstname" name="firstname" class="required" /> </p> <p> <label for="email">E-Mail</label> <input id="email" name="email" class="required email" /> </p> <p> <label for="password">Password</label> <input id="password" name="password" type="password" class="{required:true,minlength:5}" /> </p> <p> <label for="confirm_password">确认密码</label> <input id="confirm_password" name="confirm_password" type="password" class="{required:true,minlength:5,equalTo:'#password'}" /> </p> <p> <input class="submit" type="submit" value="Submit"/> </p> </form> 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 $().ready(function() { $("#signupForm").validate({ rules: { firstname: "required", email: { required: true, email: true }, password: { required: true, minlength: 5 }, confirm_password: { required: true, minlength: 5, equalTo: "#password" } }, messages: { firstname: "请输入姓名", email: { required: "请输入Email地址", email: "请输入正确的email地址" }, password: { required: "请输入密码", minlength: jQuery.format("密码不能小于{0}个字 符") }, confirm_password: { required: "请输入确认密码", minlength: "确认密码不能小于5个字符", equalTo: "两次输入密码不一致不一致" } } }); }); //messages处，如果某个控件没有message，将调用默认的信息 <form id="signupForm" method="get" action=""> <p> <label for="firstname">Firstname</label> <input id="firstname" name="firstname" /> </p> <p> <label for="email">E-Mail</label> <input id="email" name="email" /> </p> <p> <label for="password">Password</label> <input id="password" name="password" type="password" /> </p> <p> <label for="confirm_password">确认密码</label> <input id="confirm_password" name="confirm_password" type="password" /> </p> <p> <input class="submit" type="submit" value="Submit"/> </p> </form> required:true 必须有值 required:"#aa:checked"表达式的值为真，则需要验证 required:function(){}返回为真，表时需要验证 后边两种常用于，表单中需要同时填或不填的元素 demo： $("#form1").validate({//JQ 前端校验 rules: { ctl00$MainContent$txtWebName: { required: true, maxlength: 500 }, ctl00$MainContent$txtShortName: { maxlength: 500, required: false }, ctl00$MainContent$txtKeyWords: { required: false, maxlength: 500 }, ctl00$MainContent$txtGoodsNo: { required: false, maxlength: 250 }, ctl00$MainContent$txtRemark: { required: false, maxlength: 500 }, ctl00$MainContent$txtPageTitle: { required: true, maxlength: 1000 }, ctl00$MainContent$txtMetaKey: { required: false, maxlength: 1000 }, ctl00$MainContent$txtShowUrl: { required: false, maxlength: 2000, url: true }, ctl00$MainContent$txtOtherData: { required: false, maxlength: 1000 }, ctl00$MainContent$txtEC :{ required: true, digits: true}, ctl00$MainContent$txtFullEP : {required: true, digits: true}, ctl00$MainContent$txtMarketPrice : {required: true, number:true}, ctl00$MainContent$txtCash : {required: true,number:true}, ctl00$MainContent$txtDurationDays:{required: false,number:true}, ctl00$MainContent$txtFullCash:{required: true,number:true} }, messages: { ctl00$MainContent$txtWebName: "*请输入商品名[限500字以内]", ctl00$MainContent$txtShortName: "*限500字以内", ctl00$MainContent$txtKeyWords: "*500字以内", ctl00$MainContent$txtGoodsNo: "*250字以内", ctl00$MainContent$txtRemark: "*500字以内", ctl00$MainContent$txtPageTitle: "*请输入分类页面的标题", ctl00$MainContent$txtMetaKey: "*1000字以内", ctl00$MainContent$txtShowUrl: "*请输入正确的URL地址", ctl00$MainContent$txtOtherData: "*1000字以内", ctl00$MainContent$txtEC:"*只能输入整数", ctl00$MainContent$txtFullEP:"*只能输入整数", ctl00$MainContent$txtCash:"*请输入正确的现金数", ctl00$MainContent$txtFullCash:"*请输入正确的现金数", ctl00$MainContent$txtDurationDays:"必须输入数字", ctl00$MainContent$txtMarketPrice:"*请输入正确的市场价格" } }); //validate
