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.
I am developing web application and in application i need to make call of jQuery using .ajax(); method with datatype is set jsonp. Now all works well with limited data but problem start to occur when data size is increasing......
View 7 Repliesis possible to send an AJAX post with parameters and not querystring information? I have some sensitive information that I am not comfortable sending in a querystring.

I m trying to access a data after invoking a URL which redirects the output to another page with query strings.ie:
$.ajax({

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.

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.

I'm building a greasemonkey script to make posting to craigslist a lot easier for our clients.
Basically the flow is this:
User logs into our system (established authentication cookies with asp.net)User navigates to a section on our site called "CraigsList". If they have the greasemonkey script installed it automatically opens up craigslist in a new tab.
The greasemonkey script then does a request back to our site at [URL] to retrieve a list of available items to be posted to craigslist.
This is where it fails because the request to [URL] is not including any of the authentication cookies. I'm not sure if it doesn't include the cookies because the request originates from [URL] and not [URL] or what. I know it's an authentication issue because looking at it in fiddler it returns a 302 and redirects to the login page.

jQuery ajax request response is empty in Internet Explorer?
just been trying to recieve the session value from multiple jquery ajax requests on the same domain name. i think i understand that each request is kind of a virtual browser request so the session is mutally exclusive to each request, but there must be a way some how, has anyone solved this. Basically this is what im trying to do:
I have tries using type: GET and POST but still no luck.

I have an ajax call on a page which POSTS data: longitude and latitude. In the Javascript the two variables I pass in "posLong" and "posLat" are both decimals, something like: 50.81472239. When I do request.form in my .aspx.vb page which I've called, the value has now been rounded to 51.
View 4 Repliesfunction DatalistFunction(argumentid) {
set_minimum_points_for_session = value;
SetSession(set_minimum_points_for_session);
Redeem(argumentid);

this is my code which i am calling on link button onclientclick event.
sometimes what happens is redeem function gets called first and then setsession function gets called. do i need to put some delay or something between the 2 functions, so that they run everytime in their own order
I have a simple script making a request to the server:
var DTO = { 'path': path };
var url = 'default.aspx/Get';
var test;
$('#getInstance').click(function () {
$.ajax({
url: url,
type: 'POST',
dataType: 'json',
data: JSON.stringify(DTO),
contentType: 'application/json; charset=utf-8',
success: function (msg) {
test = msg;
},
error: function (jqXHR, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
});
});
This works fine as in it connects to the server and gets the data back, with one simple problem. It is treating this request as a cross domain request, therefore using jsonp. The server code is here:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static MyObject Get(string path)
{
MyObject foo = new MyObject();
return foo;
}
Normally this would not be a problem, except that I am accessing a WebMethod, and it doesnt have the capability to return a jsonp response (meaning it has no way to attach the callback function to the response. Now, if this was a manual response, I could hack it up and attach the parameter, but I am taking advantage of the built-in serialization, so no way to mess around with the response. [URL]
Let me just stress the fact that this code works. The only problem is jQuery treating this request as cross domain. But Why? UPDATE: Well, after many more hours and more testing I have narrowed this issue down to it being a bug in jquery 1.5.1. I did some testing with older versions (all 1.4 versions) and I had no problem, the request was made using JSON, and the response was received successfully. What could be the change they made that would consider this request a CORS?

I am creating a website in asp.net its a very big site about 250 pages and with a big sql database. I am confused as which ajax method i should follow. There are three options.
1. ASP.NET UpdatePanels -: Simple to use but causes a lots of uneccessary request and viewstate. I want my pages to open as quick as possible.
2.ICallback-: Causes less request and renders the page quickly. But security concerns and viewstate are there.
3.Page Methods with jQuery-: No Security anyone can quickly hack the parameters passed using "POST" mehtod.
