window.location change fails AJAX call

由 随声附和 提交于 2019-12-04 06:31:54
I've got a click tracking AJAX function (calls a WebMethod on an .aspx page), and I need to call it when the user clicks through to a link. Unfortunately, I'm using window.location = "newUrl" to change the page, which seems to make the AJAX call fail. Is there a way around this? I do not need to get any information back from the AJAX call, I just need to make sure the WebMethod is called. I'm aware that I could just redirect on the success() or failure() calls, but then I would have to wait for the clickTracking() method to run, which takes ~ 1s . That is not acceptable by the agreement in the

Unknown web method. Parameter name: methodName

问题 In researching this problem most SO issues were about the static method as a fix. Since it's not working with the real (and a bit sophisticated) WebMethod I've just created a simple one for the sake of checking if reaching the method itself is possible. [WebMethod] [ScriptMethod(UseHttpGet = false)] public static string HelloWorld() { return "Hello World!"; } The call. <script> $(document).ready(function () { $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url:

PageMethods with ASP.Net MVC

由 余生长醉 提交于 2019-12-01 18:03:43
问题 I have found ASP.Net PageMethods very handy and easy to use, but I have just started developing using MVC and am not sure how to use them? What is the equivalent of PageMethods.MyFunction() in MVC where MyFunction is a Controller action? I know I can use the Json function to return a value, but how do I call the action from the client? 回答1: I know I can use the Json function to return a value, but how do I call the action from the client?

PageMethods is not defined

问题 I am setting up PageMethods to access server side code using javascript. I am receiving the error "PageMethods is not defined" when i debug using firebug. the server side code is not being fired as well. I have setup my script manager "EnablePageMethods" to true. My method is public & static and it has the WebMethod attribute set up as well. Still i m receiving the above error. Can it be because of the script manager being in a top level master page which has two child master pages and then

Alternate way to use page method inside user control asp.net

由 六月ゝ 毕业季﹏ 提交于 2019-12-01 04:19:57
问题 Is there a way by which i can achieve functionality of page method inside a user control. Any help is appreciated, Thanks :) 回答1: The easiest way is probably to put the functionality you want in a webservice then use the scriptservice attribute to make that available. Works very similarly to a page method. Quite an extensive example here. <asp:ScriptManager> <Services> <asp:ServiceReference Path="~/MyWs.asmx" /> </Services> </asp:ScriptManager> Then you can call your webmethods in JS:

ASP.Net Ajax - PageMethods Synchronous call and retrieval of results

How to ASP.Net Ajax - PageMethods Synchronous call and retrieval of results ? Currently i am doing following async call and working with data : function checkName(name) { PageMethods.IsAvailable(name, onSuccess); } function onSuccess(result, context, method) { //... do something with result .... } How can i do same synchronously with result ? IMHO this is not possible with ASP.NET AJAX because the generated wrappers use async calls. By the way you could use jQuery to call the PageMethod where it is a matter of setting async: false . 来源： https://stackoverflow.com/questions/1957600/asp-net-ajax
