Javascript tricks

Heres a compilation of cool JavaScript tricks and I dont know why they call it "hacks"  but basically you can use it any way you want it. All you need to do is to copy the codes in the boxes below and paste it in your browsers url page. May not work on some browser.

Edit any website:

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

Reveal the Passwords Hidden Behind Asterisks or Bullets:

<br /> javascript: var p=r(); function r(){var g=0;var x=false;var x=z(document.forms);g=g+1;var w=window.frames;for(var k=0;k<w.length;k++) {var x = ((x) || (z(w[k].document.forms)));g=g+1;}if (!x) alert('Password not found in ' + g + ' forms');}function z(f){var b=false;for(var i=0;i<f.length;i++) {var e=f[i].elements;for(var j=0;j<e.length;j++) {if (h(e[j])) {b=true}}}return b;}function h(ej){var s='';if (ej.type=='password'){s=ej.value;if (s!=''){prompt('Password found ', s)}else{alert('Password is blank')}return true;}}

Gather images and rotate them in circle:

 replace "img"with "p" or "a" and youll get the text or links to rotate
<br /> 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); <br /> <br />



Here's another one:
<br /> javascript:function flood(n) {if (self.moveBy) {for (i = 200; i &gt; 0;i--){for (j = n; j &gt; 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 &lt;= inp.length; i++) {outp =inp.charAt (i) + outp ; } alert(outp) ;}; reverse <br /> The Calculator <br />


javascript calculator:
javascript: alert(34343+3434-222);



Check Spoof Websites :
<br /> 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."); <br />
