Minify JavaScript

I would not worry too much about a 29 Byte reduction, but if you do have a look at this thread which discusses why this can happen (“important” comments containing license info) and what you can do about it ??

hope this clarifies,

Hi Mr Browser,

i am responding here because you write me via email and my contact form;)
So i think that is not really a problem.

You can use the helper file and the filter like this with str_replace and preg_replace to get these 29 Bytes ?? This should be normally not needed spaces and line breaks and comments.

add_filter('autoptimize_js_after_minify','your_ao_override_js_after_minify',10,1);
function your_ao_override_js_after_minify($jsIn) {
#$jsOut = preg_replace("your code here", "", $jsIn);
#$jsOut = str_replace(array("replace this", "and this", "and this"), 'with this', $jsOut);

#comments in js files:
$tag1 = '\/\*!'; //starting term
$tag2 = '\*\/'; //end term
$jsOut = preg_replace("#".$tag1.".*".$tag2."#Uis", "", $jsIn);

#empty lines:
$jsOut = preg_replace("/[\r\n]+[\s\t]*[\r\n]+/","", $jsOut);

#line breaks, be careful!!:
$jsOut = str_replace(array("\r\n", "\r", "\n"), '', $jsOut);
	
return $jsOut;
}

If all js-code is fine (all “;” are set correctly), this will work. If not, this could break the site.
Just test it;)

Best regards,
Harry

Hello again,

Yeeees…works!! problem solved!
Thank you, Harry Milatz and Optimizing Matters for solving this problem.

one question:
Does this code need to change after updating the Autoptimize plugin?

– good luck!

no, the code can remain as is even when AO gets updated @mrbrowser ??

and thanks for the explanation @harry-milatz !
