ASP.NET MVC和WebForm 轻松实现前端和后端的双重验证 jquery.validate+ValidationSugar

上次不足的改进

可能上一个贴子给大家带来很多误解，所以我这次把DEMO完善了两个版本【ASP.NET WEBFROM】和【 ASP.NET MVC】

修改了一些BUG,并且修改了一些细了

在上个贴子里有人说，看了response.write就全身不舒服，所以也就写了基于异步提交的例子

功能介绍

ValidationSugar.cs 负责后台验证和前端 form 元素的验证属性绑定

ValidationSugar.js 对 jquery.validate在进行了一个封装来负责前端的验证

注意：ValidationSugar.cs

现在可以支持

1、HTML5默认验证功能

2、jquery.validate

3、webform demo1里面的一个HTML5+CSS3的验证

其它的前端验证可以自已去扩展

后台：

前台：

1、先引用4个脚本：

<script src="/Content/jquery-validation-1.13.1/lib/jquery-1.9.1.js" type="text/javascript"></script>
<script src="/Content/jquery-validation-1.13.1/dist/jquery.validate.js"></script>
<script src="/Content/ValidationSugar.js" type="text/javascript"></script>
<script src="/Content/jquery-validation-1.13.1/lib/jquery.form.js" type="text/javascript"></script>

2、脚本调用就这么简单

<script type="text/javascript">
     $(function () {
         var factory = new validateFactory($("form"));
         factory.init();
 
         $("#btnSubmit").click(function () {
             //异步方式
             factory.ajaxSubmit(function () {
                 $("form").ajaxSubmit({
                     type: "post",
                     url: "/home/post",
                     dataType:"json",
                     success: function (msg) {
                         alert(msg.Message)
                     }
                 })
             });
         });
 
     });
 </script>

3、HTML代码

DEMO下载地址：http://git.oschina.net/sunkaixuan/ValidationSuarMVC （包含WEBFROM）

因为才写了2天难免会有没有考虑到的地方，我在以后工作中慢慢更新的，谢谢观看。
