Greetings,

I've put together a small extension (GM AJAX) that allows for easy AJAX (Asynchronous JavaScript and XML) communication. The extension allows for multiple concurrent AJAX requests using either the GET or POST method.

View Example | Download GM AJAX | View Help File

The download includes the extension, a heavily commented example, the help file and a copy of the PHP script used to reply to the example's requests.

Hopefully some of you will find this of use.

It's certainly similar, however the most pressing difference I can see is that your requests aren't asynchronous; So the application will freeze until it receives a reply.

This also means that concurrent AJAX requests can't be made - as the application will hang until a reply to the first has arrived before making a second request.

This might not be as noticeable while testing on localhost, but it's certainly noticeable when sending requests over the internet.

Edit:
I've updated the example with a moving ball to demonstrate that the requests made are asynchronous (The program doesn't freeze while it is waiting for a reply).

Oh yeah ofcourse. It was my intention to make it wait anyway For e.g. receiving map files or loggin in.

Would you like to add this GEX to gmhtml5.net? http://forums.gmhtml...board,16.0.html

If you don't want to, then can i add it?

Cheers

You're more than welcome to link to or host a copy on your website.

Perfectly happy with people using, modifying or distributing it.

You will have to install the GEX via the extentions menu
