Cool JavaScript Tricks

Today, I will list some very cool JavaScript hacks and tricks that you can use creatively or just have plain fun. To make each one of these codes work, all you have to do is copy and paste it into the address bar of your browser window and hit “Enter”. So here they are :-

Play the “Lord of the Web”

This code lets you edit any page/website in real-time :) . With Firefox, you can even edit and save the modified pages to your computer. Very nifty code!

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

The Big Wheel

This piece of code pulls off all the images from your web page and rotates them in a circle. Really makes any page go naked (without its images). The best place to test is a website with many images. (Google Images for an example)

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0);

If you look carefully in the above code, its rotating the HTML “img” tag. Just replace it with “a” or “p” and watch some links or text rotate instead of images.

Tremors

Your browser will be very afraid of this code :) If the code below doesn’t seem to work, please replace > with > and < with <

javascript:function flood(n) {if (self.moveBy) {for (i = 200; i > 0;i–){for (j = n; j > 0; j–) {self.moveBy(1,i); self.moveBy(i,0);self.moveBy(0,-i); self.moveBy(-i,0); } } }}flood(6);{ var inp = “D-X !msagro na dah tsuj resworb rouY”; var outp = “”; for (i = 0; i <= inp.length; i++) {outp =inp.charAt (i) + outp ; } alert(outp) ;}; reverse

The Calculator

In case you are not in a mood to use the standard windows calculator and want your browser to do the dirty job for you, use this code.

javascript: alert(34343+3434-222);

You can change the numbers according to your choice and also try creative complex equations. Just put your arithmetic into javascript: alert( );

Finding Spoof Websites

There are times when you are not sure that the website that you are visiting is authentic. Use this code whenever in doubt :-

javascript:alert("The actual URL is:\t\t" + location.protocol + "//" + location.hostname + "/" + "\nThe address URL is:\t\t" + location.href + "\n" + "\nIf the server names do not match, this may be a spoof.");

And finally here is something that you can only get to hear if you ever worked in a Tech Support department :(

    Thanks for finally talking about > Blog Oh Blog ? Blog Archive ? Cool JavaScript Tricks < Loved it!

  4. Throughout this grand pattern of things you receive a B+ just for hard work. Where exactly you misplaced me was first on the particulars. You know, as the maxim goes, details make or break the argument.. And that could not be much more correct at this point. Having said that, allow me tell you exactly what did do the job. Your writing is highly persuasive which is possibly the reason why I am taking an effort in order to opine. I do not really make it a regular habit of doing that. Secondly, although I can certainly notice the jumps in reasoning you come up with, I am not really sure of just how you appear to connect the details which in turn make the actual conclusion. For the moment I will subscribe to your issue however hope in the future you actually link the facts much better.

    • yes they do, atleast on mine. you cant copy paste it tho, you need to enter the whole thing by hand.

    • Spencer says:

      If you want to do it in chrome or FireFox, just go to any random website, add it as a bookmark, then click on the bookmark and click Edit. , then delete the URL and copy and paste the code into the URL box, then go to any website, click on the bookmark and now you can use that code for that site!

  64. Anonymous says:

    None of them worked, errors:

    (1) Expected Objects
    (2) Did not close parenthesis
    (3) Did not define “document”

    These errors were found when saved from Notepad as the .js format, maybe I did that wrong? Hopefully you can fix that!

    Thanks!

  74. Dexter says:

    I can note something interesting with Google Notebook by selecting the text and just clicking a bookmark “javascript:(function(){var w=window;var d=document;var g=w.open(‘about:blank’,'gnotesWin’,'location=0,menubar=0,scrollbars=0,s”. However, Google Notebook limits the number of words in a single Note. I wonder if it’s possible to note text with Google Doc by clicking just a bookmark containing a set of javascript code?

  75. Ryan says:

  98. I often find something cool like this and think “Interesting, but I don’t think I could use this anywhere.” … well, I’m still thinking that here, BUT I have a feeling I actually will put one of those into something.

    I don’t get your instructions under Tremors. Replace what?
