AJAX browser-dependent limit on length of data sent? (SAJAX)

EDIT: now the question becomes, how do I tell Sajax to use POST instead of GET? I've tried some examples from google but they are sketchy, and as I said, they didn't work. I know, we're all jQuery nuts around here. I've used the following code to try and find a limit to the amount of data that can be sent to the server via an ajax cal...

How to validate a user through an AJAX request?

We have a webpage that we provide to partner companies via an iFrame. The iFrame contains several javascript files that make ajax requests to our server for data.

Hosted Microsoft Ajax on CDN?

Google hosts popular ajax libraries for free at : http://code.google.com/apis/ajaxlibs/ You get to take advantage of their bandwidth, their CDN and most importantly that users may already have it cached from another site that is retrieving their JS files from google.

What's Django's equivalent of "replace_html" in Rails?

I'm wondering what a controller - such as the following Rails controller - would look like in Django, to perform an ajax update of the page after an asynchronous form submission (assuming the following is correct): def create @omelet = Omelet.new(params[:omelet]) render :update do |page| if @omelet.save page.replace_html 'notice',...

Is it possible to gracefully handle a Google Maps AJAX request timeout?

My site uses the Google Maps API. In situations where the connection to Google is slow and the map can't be rendered in a reasonable time, I'd like a Javascript callback method to be called such that I can display a useful message to the user rather than have a 'loading...' message constantly displayed. Is this achievable? ...

How much javascript is too much

Dojo "loading"-message

I'm new to Dojo, so I need a little help. Some of my links takes a while (when the user clicks, it takes several seconds before the page starts loading), and I'd like to add a "loading"-message.

Hello, I have the following part of an AJAX application, which gives no errors, but also nothing is displayed to the screen, so I am unsure of where the problem lies.

Hi, I am firing an Ajax request using jQuery. During the process, I show a loading text to the user till it reaches the success/errorhandler function. Is there a way to abort the request in middle of it. So that it doesn't goes to the success/errorHandler variable. One way I can think of is using a global variable. Is there a better meth...

AJAX call to asp from bookmarklet

I'm trying to create a bookmarklet that will start off an AJAX call to an aspx page I've written. The code tests out perfectly when I place the javascript in a static html page, but when I try and call it off from a bookmarklet, the code will just hang at the xmlHttp.open("GET", url, true) part.

Is there a super-high-load (Ajax) chat script out there?

For a pet project, I have been looking for a web chat script capable of running potentially tens of thousands of users simultaneously. I don't want to use any kind of applet or browser extension, so on the client side, it should be simple Ajax. On the server side I'm pretty much open to anything. I'm not looking for bells and whistles, ...

Notifying the user after a long Ajax task when they might be on a different page

I have an Ajax request to a web service that typically takes 30-60 seconds to complete. In some cases it could take as long as a few minutes. During this time the user can continue working on other tasks, which means they will probably be on a different page when the task finishes. Is there a way to tell that the original request has be...
