javascript tricks

CALCULATOR : Using this javascript you can use your web browser as an calculator. Just replace  the below value for what ever mathematical calculation you want.    

          javascript: alert(4+5+6+7+(3*10));

EDIT ANY WEBPAGE : Using this javascript you can edit any webpage. The changes are not permanent as soon as you will refresh the page the changes will be lost.

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

IMAGES FLY OVER WEB PAGE : For this javascript to work there must be some pictures in the website. I will prefer you to try this javascript on facebool as it will show cool effect.

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);
