Hi, are you sure about the script not caching as one of the first questions on the jQuery documentation page for .getScript() states that it DOES cache!!

See here: http://api.jquery.com/jQuery.getScript/

[...] 解法參照http://jamiethompson.co.uk/web/2008/07/21/jquerygetscript-does-not-cache/ 原來$.getScript()也有同樣的問題，解法就是使用jQuery低階ajax API 。 [...]

Brilliant! Thanks. I’m grateful for folks who take the time to post solutions to little issues like this. Good job.

Incidentally, I can confirm that in use the script that is retrieved does indeed get executed without a callback specified.

Christian: “It should be noted that using $.ajax(…) like explained above will only work, if the caller provides a callback. Therefore this re-definition of getScript does not everything that getScript does – it will not auto-execute the code, if no callback is specified.”

I think you’re mistaken. I’m finding the solution performs as stated on FF 3.5, Safari 4 and IE 6 & 7.

Looking the jquery source show’s that since the dataType is set to “script”, jquery builds a script tag and sets the src attribute to the url passed. This occurs around line 3473 in jQuery 1.3.2.

P.S. – those who do not want to use eval(..), for example because the YUI compressor will then do less minification, can also do that:

$.get(url, {},
function(data){ (new Function(data))(); }
);

This will create a function around the loaded code and then execute this function, which will not affect Yahoo’s minification behavior.

This post is rather old, but since people continue to comment, I thought, I may do so as well.

It should be noted that using $.ajax(…) like explained above will only work, if the caller provides a callback. Therefore this re-definition of getScript does not everything that getScript does – it will not auto-execute the code, if no callback is specified.

Loading and executing a script while allowing caching, can also be done like that:

$.get(url, {},
function(data){eval(data);}
);

In that case, the browser will just issue a normal get request without any added parameters.
