I want to compress my 2000+ lines of javascript and I have tested both http://dean.edwards.name/packer/ and http://closure-compiler.appspot.com/home.
But in both cases, the compressed script gives me errors.
An example of an error is jQuery(document).Da is not a function.
Why isn't my script working after optimization? And what can I do to optimize / compress my script?
You could try an online YUI Compressor. This is the first result on google: http://www.refresh-sf.com/yui/
