数据注释 - asp.net mvc 4

I m new to MVC. I have make a model LoginModel

我是MVC的新手。我已经制作了一个模型LoginModel

{
    [Required (ErrorMessage="Username is required field.")]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required (ErrorMessage="Password is required field.")]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }
}

and design a Form for it with id = "CustomLogin" and its action="User/Validate" and Validate action returns JsonResult

并为其设计一个表单,其中id =“CustomLogin”,其action =“User / Validate”,Validate操作返回JsonResult

In web.config,

<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />

In my _Layout.cshtml,

在我的_Layout.cshtml中,

@Scripts.Render("~/bundles/jqueryval")

Now, if i directly click on "Submit" button of form (CustomLogin), so it prevents me to jump User/Validate that is right..

现在,如果我直接点击表单(CustomLogin)的“提交”按钮,那么它阻止我跳转正确的User / Validate ..

But in external Javascript say mycode.js, I have also written

但在外部Javascript中说mycode.js,我也写过

 $(document).ready(
     function()
     {
          $('#CustomLogin').submit(
            function(e)
            {
               alert ('i executed.');
               //suppose, here i wrote JSON call, it will also be executed
            });
     });

It is also executed. So is it OK..??

它也被执行。好吧.. ??

My thinking is if I click on submit button, without passing any value,

我的想法是,如果我点击提交按钮,没有传递任何价值,

Unobstrusive javascript prevents jumping control over my post request "User/Validate",

不引人注目的JavaScript可以防止对我的帖子请求“用户/验证”进行跳转控制,

then it should also prevent my submit event. To solve this, I have used $("form").valid() in my submit event handler.

那么它也应该阻止我的提交事件。为了解决这个问题,我在提交事件处理程序中使用了$(“form”)。valid()。

like this,

  if ( $("#CustomLogin").valid() ) 
  {
       alert('I executed.');
  }

I think Unobstrusive javascript makes form state : invalid or valid...

我认为Unobstrusive javascript使表单状态:无效或有效...

**> BUT, my question is if I need to use $("form").valid(), then WHAT IS

**>但是,我的问题是我是否需要使用$(“form”)。有效(),然后是什么

USE OF Unobstrusive javascript for validation...???? **

使用不引人注目的javascript进行验证...... ???? **

So is this OK.. or i m doing in wrong manner

这样可以......或者我做错了

Because your model is invalid, doesn't necessarily mean you don't want to communicate with the server. It just means you don't want to submit that model.

因为您的模型无效,并不一定意味着您不想与服务器通信。它只是意味着您不想提交该模型。
