[jQuery] Re: Can't Get Data Back from $.ajax() Call in IE7?

[Vik]

Fixed it!

Once I realized it was working on Firefox/Win XP, but not IE7/Win XP,
I did some more googling on this group, and found this post:

Using $.post() instead of $.ajax() or $.getJSON() fixed it.

For reference for anyone trying this out, here's the skeleton code.

JQUERY:
        $.post("/myFunction", {variable1: 'TestVariable'}, function(data){

                var data = JSON.decode(data);  //uses json_min.js plugin

                //use data
        });


PHP:
        //put data to be retuned into array called $theData

        $S = $this->json->encode($theData); //uses a jason encoder - which
one depends on your development environment

        echo $S;

        return;
