Select All checkbox by Javascript or console

Question

I am having 100 Checkboxes on my web page. For testing purposes I want to tick all those boxes, but manually clicking is time consuming. Is there a possible way to get them tick

Answer 1

Pure JS method, don't use jQuery.. its just silly for something so trivial.

[].forEach.call( document.querySelectorAll('input[type="checkbox"]'),function(el){
       el.checked=true;
     }
);​

To use it on any webpage you can paste this into the address bar

javascript:[].forEach.call(document.querySelectorAll('input[type="checkbox"]'),function(el){el.checked=true});

then drag that to your bookmarks, and you have a bookmarklet. Just click it whenever you need to use it on a page.
