I was looking at a Wassat (Wellington Open Source Show & Tell) notice and looked back at one of the organisers, Grant, presentation on Bookmarklets on YouTube and slides. I thought it was an interesting idea and decided to explore it further. <\/p>\n\n\n\n
Basically you do add Javascript to the Address bar on a browser. This Javascript usually loads after the page has loaded, then it creates an event on that page. You can have it as a simple bookmark on your Bookmark Toolbar, just like any other Bookmark and with Firefox you can even assign a hotkey to it as well. <\/p>\n\n\n\n
As you are doing the JS event after the page has loaded, and you have a script that changes the background colour of the page, you can go back to prior running of Bookmarklet by just refreshing the page and it brings you back to the original page load state. <\/p>\n\n\n\n
Sounds cool and I was intrigued by it. So I started by wonder exactly what you could do to on mr YouTube. The code train one shows how to build them and challenges (no new lines in JS) but his examples are a bit weak. The 2nd video discusses a webpage mrColes<\/a><\/strong> that takes your JS and converts it into a Bookmarklet:<\/p>\n\n\n\n
