Use jQuery.ajax (or it's wrapper functions such as jQuery.getJSON) to
cover all cross-browser issues.
And as indirectly suggested above. JSONP is the solution for cross-
domain scripting.
What it means is that that source (in this case toolserver) has a URL
parameter (say &callback=), the script then returns the folllowing:
callback({ my: 'data' });
This is the exception / work-around to same origin policiy as it can
be done through a simple script tag because there is a callback.
This callback function can be dynamic and generated on the fly with
jQuery by using a ? as callback
Example:
http://toolserver.org/~krinkle/tmp/jsonp_example.php?callback=myFunc
jQuery.getJSON( 'http://toolserver.org/~krinkle/tmp/jsonp_example.php?callback=
?', function(data){
alert(data.hello); }
);
