Bookmarklet via Javascript Primer Tutorial
Have you heard of Bookmarklets?
Are you a person with a cluttered (thoughtfully placed, of course) desk?
Yes? Read on … even if not … read on … why?
<html>
<head>
</head>
<body>
<script type=”text/javascript”>
while (“abracadabra” != prompt(“Guess the magic word?”).toLowerCase()) {
alert(“Bad Luck”);
}
document.write(“<html><body><p>You win a cupee doll!</body></html>”);
</script>
<a href=’#’ onclick=’javascript: while (“abracadabra” != prompt(“Guess the magic word?”).toLowerCase()) { alert(“Bad Luck”); } document.write(“<html><body><p>You win a cupee doll!</body></html>”);’>Click me for another (confirmed) go … but limited offer on cupee dolls!</a>
</body>
</html>
Look at the cutesy wootsey HTML/Javascript above. Isn’t it cuuuuuuute?!
Isn’t it sweeeeeet?!
♫ Oh, aint she sweet, when she’s walking down the street,
Well I ask you very confidentially … aint … she … sweet. ♫
Enough of a sell job?
Okay look at the Javascript of one vs Javascript of one below in the a tag onclick bit. So you just place javascript: in front of the Javascript code required to do something interesting, all squeezed together onto the one line … this is where the cluttered desk people may continue breathing easily but others may falter.
Well, if you can place this sort of thing into a browser Bookmark then that is a
Bookmarklet. Remember the Javascript calculator rave in previous tutorials?
Bear in mind we show Firefox in tutorial but all browsers have something similar, whether that be called Bookmarks or Favourites.

Link to downloadable source code of HTML above is bmark.html which you need to rename in order to try.
Did you know …
JavaScript makes a great easy-access Calculator?
Try typing the lines below into the address bar of your favourite browser:
Javascript: eval(512 / 380);
Javascript: eval(512 * 380);
Javascript: eval(512 – 380);
Javascript: eval(512 + 380);
Javascript: eval(512 % 380);
These days we spend so much time on the Internet it is a much quicker way to get to a calculator!
