Greasemonkey - replace javascript src to load custom JS instead the one of the page
There's specific webpage with variable in .js file. I want to rewrite the URL to be loaded with Greasemonkey, but still haven't got any results.The code I use is: window.addEventListener( 'load', function() { allTextareas = document.getElementsByTagName('script'); for (thisTextarea in allTextareas) { if( allTextareas[thisTextarea].getAttribute('src') == 'some url.js' ){ //allTextareas[thisTextarea].setAttribute('src', 'http://my custom url.js'); } } }, true); but it's not working. Can you help me, or just tell me a way to edit JS files on specific page.. A couple things, easy one first... (1)
