C# - How To Fetch Return Values Between Jquery Functions And Post Ajax Jquery Request To Webservice
Aug 26, 2010
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
im working on a MVC 3 webapp where i want to post to a controller function using jQuery ajax. However, every time i post to the server i get a 400 Bad Request response and i can't figure out where this comes from as the site runs fine with the VS2010 devserver.
See the function im using to send the ajax post below:
I need to pass a customer id to get some data back for a customer from a webservice. I can't figure out how to get to the webservice, I have a breakpoint set in the webmethod but it's not being hit and the alert box is not popping up either. For a test I am just trying to show some value from the returned data in an alert box. Note I am just hard coding the customer id of 1001. The webmethod takes a parameter of string customerid.
[Code]....
Does some one know what's missing or how to debug this issue?
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
which returns <div>here</div><script language=javascript>alert('');</script> The content gets loaded property, but no alert. How would I get a javascript routine to work from an ajax call along with posting the HTML code?
I developed a website in ASP.NET with huge Database, Now i have another website in HTML & PHP. I want to make user login authentication from HTML website which will authenticate the login details from the old website's Database.
Database used is SQL Server 2005.
I Created t HttpHandler to authenticate the user in old website.
I want to make a JQuery request from HTML website to old website which will authenticate login details and will redirect to the user to new page according to user type.
I have been reading that a value needs to be returned by a function, otherwise the following error will occur:
"Function <function name> doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used."
The cure, I have found, is to return something (i.e. "Return 0") before exiting the function. Can I pass this return value back to the routine that called the function? If so, how do I code this?
Most of the time, however, I find I'm not needing to return a value anyway, and just end up adding "0" to the ends of all my Return statements. Does anyone have any comments on this?

I have a web Method in my C# that is called via Jquery ajax method. The web method should return an object back to the Jquery which will be used to populate. I have tried returning a JsonResult object, the actual object and nothing seems to work! I'm not using MVC (Unfortunately). Is there a way that I can return an object from my web method which can be used by my AJAX method? here is the link for my JQuery AJAX method [URL]
Reponse results empty. This URL is a redirect to another page with query string, I already have a page that parses the query string and write the output to a page.But response is blank.
I am just wondering that, is there anyway to make an Ajax request using jquery ("$.ajax") and making partial rendering without using the .NET Ajax framework (without script manager).
I have tried this before, but it's executing the page_load every time and not reaching to the pagemethod.
I haven't used Jquery to post Json data to mvc before, so this maybe a Noob issue.
I've got a really simple form, and am trying to post this data async to an mvc action. Within firefox I can see the data being posted, but I can't see it within the MVC action.
This code all runs through correctly, but putting a debug point in the action method will always show the form collection as empty.
I was just wondering if its possible to do an ajax post a file in asp.net mvc,basically i have a form with two buttons, one of the buttons extracts images for the selected document and displays them for the user to choose thumbnails for the document he is about to upload. The usee then fills out the rest of the form and then saves the document.With the image extraction, I was owndering if it was possible to do that as an ajax post. The other submit button can work as a normal http post
