Estrellas
Descripción:
Este javascript crea unas estrellas de colores q giran alrededor del puntero del ratón, es recomendable q uses un fondo oscuro para q se pueda ver el efecto con claridad.
Ejemplo:
Mira el puntero del ratón.
Primero debes introducir este código en <head>:
<style type="text/css"> <!-- Begin CSS #a { position: absolute; top: 10px; left: 10px; visibility: visible } #b { position: absolute; top: 10px; left: 10px; visibility: visible } #c { position: absolute; top: 10px; left: 10px; visibility: visible } #d { position: absolute; top: 10px; left: 10px; visibility: visible } #e { position: absolute; top: 10px; left: 10px; visibility: visible } #f { position: absolute; top: 10px; left: 10px; visibility: visible } #g { position: absolute; top: 10px; left: 10px; visibility: visible } End CSS --> </style>
Y después este en <body>:
<layer name="a0" left=10 top=10 visibility=show bgcolor="#ff0000" clip="0,0,2,2"></layer> <layer name="a1" left=10 top=10 visibility=show bgcolor="#ff8000" clip="0,0,2,2"></layer> <layer name="a2" left=10 top=10 visibility=show bgcolor="#ffff00" clip="0,0,2,2"></layer> <layer name="a3" left=10 top=10 visibility=show bgcolor="#00ff00" clip="0,0,2,2"></layer> <layer name="a4" left=10 top=10 visibility=show bgcolor="#0000ff" clip="0,0,2,2"></layer> <layer name="a5" left=10 top=10 visibility=show bgcolor="#ff00ff" clip="0,0,2,2"></layer> <layer name="a6" left=10 top=10 visibility=show bgcolor="#ffffff" clip="0,0,2,2"></layer> <div id="starsDiv" style="position:absolute;top:0px;left:0px"> <div style="position:relative;width:2px;height:2px;background:#ffffff;font-size:2px;visibility:visible"></div> <div style="position:relative;width:2px;height:2px;background:#ffff00;font-size:2px;visibility:visible"></div> <div style="position:relative;width:2px;height:2px;background:#ffa000;font-size:2px;visibility:visible"></div> <div style="position:relative;width:2px;height:2px;background:#ff0000;font-size:2px;visibility:visible"></div> <div style="position:relative;width:2px;height:2px;background:#00ff00;font-size:2px;visibility:visible"></div> <div style="position:relative;width:2px;height:2px;background:#0000ff;font-size:2px;visibility:visible"></div> <div style="position:relative;width:2px;height:2px;background:#FF00FF;font-size:2px;visibility:visible"></div> </div> <script language="JavaScript"> <!-- Original: freeware.de --> <!-- Web Site: http://freeware.de --> <!-- MSIE Fix by: Kurt Grigg (kurt.grigg@virgin.net) --> <!-- Begin if (document.layers) { window.captureEvents(Event.MOUSEMOVE); } var yBase = 200; var xBase = 200; var yAmpl = 10; var yMax = 40; var step = .2; var ystep = .5; var currStep = 0; var tAmpl=1; var Xpos = 1; var Ypos = 1; var i = 0; var j = 0; if (document.all) { function MoveHandler(){ Xpos = document.body.scrollLeft + event.x; Ypos = document.body.scrollTop + event.y; } document.onmousemove = MoveHandler; } else if (document.layers) { function xMoveHandler(evnt) { Xpos = evnt.pageX; Ypos = evnt.pageY; } window.onMouseMove = xMoveHandler; } function animateLogo() { if (document.all) { yBase = window.document.body.offsetHeight / 4; xBase = window.document.body.offsetWidth / 4; } else if (document.layers) { yBase = window.innerHeight / 4; xBase = window.innerWidth / 4; } if (document.all) { for (i = 0 ; i < starsDiv.all.length; i++) { starsDiv.all[i].style.top = Ypos + Math.cos((20*Math.sin(currStep/20))+i*70)*yBase*(Math.sin(10+currStep/10)+0.2)*Math.cos((currStep + i*25)/10); starsDiv.all[i].style.left = Xpos + Math.sin((20*Math.sin(currStep/20))+i*70)*xBase*(Math.sin(10+currStep/10)+0.2)*Math.cos((currStep + i*25)/10); } } else if (document.layers) { for (j = 0; j < 7; j++) { //7 is number of NS layers! var templayer="a" + j; document.layers[templayer].top = Ypos + Math.cos((20*Math.sin(currStep/20))+j*70)*yBase*(Math.sin(10+currStep/10)+0.2)*Math.cos((currStep + j*25)/10); document.layers[templayer].left =Xpos + Math.sin((20*Math.sin(currStep/20))+j*70)*xBase*(Math.sin(10+currStep/10)+0.2)*Math.cos((currStep + j*25)/10); } } currStep += step; setTimeout("animateLogo()", 10); } animateLogo(); // End --> </script>
