如何调用从jQuery的asp.net方法 [英] how to call asp.net method from Jquery

问题描述

大家好我有一个使用jQuery从对话框使用$阿贾克斯的asp.net方法发送的数据的网页，但它总是给我一个404错误网页没有找到。

Hi everyone I have a web page that is using Jquery to send the data from a dialog to the asp.net method using $.ajax, but it's always giving me a 404 error Web Page not found.

阿贾克斯是给这个链接的请求。本地主机：1395 /的Login.aspx / sendEmail（使用萤火虫获得），但发Email是应该在网页的Login.aspx被称为法

The Ajax is giving this link to the request "Localhost:1395/Login.aspx/sendEmail" (Obtained using firebug), but send Email is the method that should be called in the Login.aspx page.

这是JQuery的code：

This is the JQuery code:

   $.ajax({
       type: 'POST',
       url: 'Login.aspx/sendEmail',
       data: '{"strEmail":"' + $('#hplForgotDialog').find('input[id$=txtForgotEmail]').val() + '"}',
       contentType: "application/json; charset=utf-8",
       dataType: "json"
   });

这个问题的任何帮助将是一个真正的preciated。

Any help with this problem would be really apreciated.

编辑：证明错误的更多一点，我会添加一个图像描绘了URL错误魔域它会尝试连接

to demonstrate the error a little more I'll add an image depicting the URL error to witch it tries to connect.

推荐答案

我的猜测是，你需要设置路由。你可以在这里读到它：

My guess would be, you need to setup routing. You can read about it here: http://msdn.microsoft.com/en-us/library/cc668201.ASPX

基本上，如果我是正确的（我至极可能不是），你的路由没有找到正确的动作（或不管他们被称为在非MVC的情况）。在Web窗体，你必须在Global.asax文件设置的自定义路线，在Application_Start事件处理程序。

Basically, if I'm right (wich I might not be), your routing doesn't find the correct Actions (or whatever they are called in a non-MVC scenario). In Web Forms, you have to setup custom routes in the Global.asax file, in the Application_Start event handler.

事情是这样的：

protected void Application_Start(object sender, EventArgs e)
{
    RegisterRoutes(RouteTable.Routes);
}

public static void RegisterRoutes(RouteCollection routes)
{
    routes.MapPageRoute("",
        "Category/{action}/{categoryName}",
        "~/categoriespage.aspx");
}

有了这个，你告诉应用程序如何理解URL和它们的参数。这是URL /分类/参数1 /参数2，这个模式匹配的一切，将被引导到categoriespage.aspx页面，有什么可以做任何它想要的参数（调用例如正确的方法）。

With this, you tell the application how to understand URLs, and their parameters. This is the url /Category/param1/param2, everything that matches this pattern, will be directed to the categoriespage.aspx page, what can do whatever it wants with the parameters (call the correct method for example).
