I want to run a javascript on a website, but when I do it, nothing changes, I get the pdf as if I run no result of the javascript on it, this is an example of what I do:
xvfb-run --server-args="-screen 0, 1024x768x24" wkhtmltoimage --run-script "javascript:(\$(function(){ \$("div").hide() ;}))" google google.png
I have also scripts without jquery like:
xvfb-run --server-args="-screen 0, 1024x768x24" wkhtmltopdf --run-script "javascript:(function(){ document.write("AHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"); ;})" google p2.pdf
But as I said, no effect on the pdf or the png (because I have tried both wkhtmltoimage and wkhtmltopdf).

Reset to default 10Your command uses quotes incorrectly; try this:
--run-script "javascript:(\$(function(){ \$('div').hide() ;}))"
Also, try increasing the JavaScript delay:
--javascript-delay 1000

About the question
"do you know any way of generate a .png with less size? cause every png I generate weights 9MB"
I had the same problem with large PNG files generated with wkhtmltoimage and managed to fix this with adding the flag --quality 0, that shrunk the image from 3.5MB to just 38KB. Note that PNG is doing lossless compression so the image quality won't change only will be shrunk in size. Be careful when using --quality flag when you output to jpg format as this can blur the image is you set it too low.
