jQuery的asp.net按钮通过ajax点击事件 [英] Jquery asp.net Button Click Event via ajax

问题描述

我想知道如果任何人都可以在正确的方向指向我。 我有一个asp.net按钮点击事件（即运行一些服务器端code）。 我想要做的是通过AJAX和jQuery调用此事件。 有没有办法做到这一点？如果是的话，我会喜欢一些例子。

I was wondering if anyone can point me in the right direction. I have an asp.net button with a click event (that runs some server side code). What i'd like to do is call this event via ajax and jquery. Is there any way to do this? If so, i would love some examples.

在此先感谢

推荐答案

这是jQuery的真正出色的ASP.Net开发。可以说，你有这样的ASP按钮：

This is where jQuery really shines for ASP.Net developers. Lets say you have this ASP button:

在呈现，你可以看网页的源代码和它的ID不会btnAwesome，但$ ctr001_btnAwesome或类似的东西。这使得它成为讨人厌找到的JavaScript。进入jQuery的。

When that renders, you can look at the source of the page and the id on it won't be btnAwesome, but $ctr001_btnAwesome or something like that. This makes it a pain in the butt to find in javascript. Enter jQuery.

$(document).ready(function() {
  $("input[id$='btnAwesome']").click(function() {
    // Do client side button click stuff here.
  });
});

中的id $ =正在做一个正则表达式匹配的ID与btnAwesome结局。

The id$= is doing a regex match for an id ENDING with btnAwesome.

编辑：

你想要的Ajax调用从客户端上的按钮点击事件被称为？你想怎么称呼？有很多真正的好文章对使用jQuery做AJAX调用后面的方法ASP.Net code。

Did you want the ajax call being called from the button click event on the client side? What did you want to call? There are a lot of really good articles on using jQuery to make ajax calls to ASP.Net code behind methods.

它的要点是你创建一个静态标记有WebMethod属性的方法。然后，您可以打电话到它使用jQuery使用$阿贾克斯。

The gist of it is you create a static method marked with the WebMethod attribute. You then can make a call to it using jQuery by using $.ajax.

$.ajax({
  type: "POST",
  url: "PageName.aspx/MethodName",
  data: "{}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
    // Do something interesting here.
  }
});

我知道我的WebMethod的东西从：<一href="http://encosia.com/2008/05/29/using-jquery-to-directly-call-aspnet-ajax-page-methods/">http://encosia.com/2008/05/29/using-jquery-to-directly-call-aspnet-ajax-page-methods/

很多真正的好ASP.Net/jQuery的东西在那里。请务必阅读了为什么你必须使用msg.d在NET 3.5的回报（也许因为3.0）的东西。

A lot of really good ASP.Net/jQuery stuff there. Make sure you read up about why you have to use msg.d in the return on .Net 3.5 (maybe since 3.0) stuff.
