Programming JavaScript Interesting and Effective JavaScript codes

These effective javascript codes need not to write in a html document. You just copy and then paste them in the browser's address bar, then press enter or click the "goto" button would be ok.

The following codes would extract all the pictures in a web page then roll then on the screen.

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.images; 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;*y1+i*y2+y3)*y4+y5}R++}setInterval('A()',5); void(0);

This code would leave you to edit the current html document you are viewing.

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

Notice that you have to first navigate the browser to a site page before you runs the codes to check the effect.
