Dancing Gifs

In a Nutshell: Allow your images to dance freely across the screen with this free Javascript. Still and animated gifs alike can now enjoy freedom from the tyranny of design and static placement.

Use it Yourself: Copy the code from below and paste it within the <head> section of your HTML code. This is the portion that drives the movement, and can be modified without too much trouble.

<script language=javaScript>    function setVariables(){ if (navigator.appName == "Netscape") { horz=".left"; vert=".top"; docStyle="document."; styleDoc=""; innerW="window.innerWidth"; innerH="window.innerHeight"; offsetX="window.pageXOffset"; offsetY="window.pageYOffset"; objectXY="layers[0]"; }else{ horz=".pixelLeft"; vert=".pixelTop"; docStyle=""; styleDoc=".style"; innerW="document.body.clientWidth" innerH="document.body.clientHeight" offsetX="document.body.scrollLeft" offsetY="document.body.scrollTop" objectXY="object1" } } function checkLocation(){ imgwidth=79; // logo width, in pixels imgheight=70; // logo height, in pixels var availableX=eval(innerW) var availableY=eval(innerH) var currentX=eval(offsetX) var currentY=eval(offsetY) xmax=availableX-(imgwidth+20)+currentX ymax=availableY-(imgheight+20)+currentY } var x=-100; var y=50; var a=5; var b=5; function startMoveR(){ checkLocation(); x += a; y += b; if (y>ymax) b=b*-1 if (y<10) b=b*-1 evalMove(); if (x<xmax+20) setTimeout("startMoveR()",100); else setTimeout("startMoveL()",100); } function startMoveL(){ checkLocation() x -= a; y += b; if (y>ymax-15) b=b*-1 if (y<10) b=b*-1 evalMove(); if (x>0) setTimeout("startMoveL()",100); else setTimeout("startMoveR()",100); } //****************************** function evalMove(){ eval(docStyle + objectXY + styleDoc + horz + "=" + x); eval(docStyle + objectXY + styleDoc + vert + "=" + y); //setTimeout("checkLocation()",10) //****************************** } </script>

Next, the following Javascript component must be placed within the <body> section of your HTML code. The onload commands must be added to your <body> tag.

<BODY onload="setVariables(),startMoveR()" bgcolor=#004080> <div id="object1" style="position:absolute; visibility:show; left:-100px; top:50px; z-index:2"> <table><td><img src="../midi/ladyred/dancing.gif" width="62" height="68"></td></table></div>
