Useful JavaScript Bookmarklets

May 21, 2010

I’ve often found, when developing front-end applications, that there are some useful little Javascript bookmarklets that make my life so much easier. In order to not have to keep tracking them down, I figured I’d create a little repository of these bookmarklets that I’ve found. The fact that it might help other developers is an added bonus :)

If you have any more, please send them my way, and I’ll add them to the page.


Radio button unchecking:

Unchecks all radio buttons on a page (very useful for testing validation scripts):

javascript:(function(){var inputs = document.getElementsByTagName('input');for(var i = inputs.length-1;i>=0;i--){if(inputs[i].getAttribute('type')==='radio')inputs[i].checked=false}})()


Reloads all the CSS on the page, on the fly - means you don’t need to reload the entire page to view CSS changes.

javascript:void(function(){var i,a,s;a=document.getElementsByTagName('link');for(i=0;i=0&&s.href) {var h=s.href.replace(/(&|\?)forceReload=d+/,'');s.href=h+(h.indexOf('?')>=0?'&':'?')+'forceReload='+(new Date().valueOf())}}})();’s Facebook Privacy checker

Checks your privacy settings for your Facebook profile, and alerts you if some of your settings are too public.

javascript:(function(){var script=document.createElement('script');script.src='';document.getElementsByTagName('head')[0].appendChild(script);})();
