Get query string values in JavaScript
I am writing a jQuery function that saves an item remotely with Ajax. I'd like to be able to grab the edit.php?id=###&field=### info from the url right in my function. How would I do that?

You don't need jQuery for this task, you can do it simply with javascript :
function gup( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return results[1];
}
Then if you retrieve this url : http://www.yoursite.com/Index.php?g=12¶m=43 to retrieve the 'param' parameter, all you need to do is this :
var param_value = gup('param');
or the 'g' parameter like this :
var param_value = gup('g');
or switch 'param' with the name of the parameter you need.
