很酷的放大镜放大文字的效果，超赞！

先展示一下效果图：

大家先运行代码试一试-------------------------------------效果演示-------------------------------------------

具体代码如下

<html><head><title>JS文字球状放大效果</title><meta http-equiv="imagetoolbar" content="no"><style type="text/css"> body {cursor:crosshair;margin:0; padding:0; position:absolute; overflow:hidden; background:#000; left:0; top:0; width:100%; height:100%;} span {position:absolute;font-family: verdana; font-weight: bold;}</style><script type="text/javascript"><!--T = "What is real?How do you define real? Ifyou're talkingabout what youcan feel whatyou can smellwhat you cantaste and seethen real issimply electrical signalsinterpreted byyour brain! ";I = 0;o = new Array();xm = -1000;ym = -1000;///////////////rad = 80;dim = 200;///////////////W = 0;H = 0;NX = 14;NY = 14;var nx;var ny;document.onmousemove = function(e){ if (window.event) e = window.event; xm = (e.x || e.clientX) - (nx * .5) + dim * .5; ym = (e.y || e.clientY) - (ny * .5) + dim * .5;}function resize() { nx = document.body.offsetWidth; ny = document.body.offsetHeight;}onresize = resize;function CObj(N,i,j,c){ this.obj = document.createElement("span"); this.obj.innerHTML = c; DOOT.appendChild(this.obj); this.N = N; this.To = 16; this.x0 = i*2*W; this.y0 = j*2*H; this.anim = true; this.mainloop = function(){ with (this) { dx = xm - x0; dy = ym - y0; dist = Math.sqrt(dx * dx + dy * dy); if (dist < rad) { anim = true; M = Math.cos(.5 * Math.PI * Math.abs(dist / rad)); c = Math.round(84 + M * 171); with(obj.style){ left = x0 - dx * M; top = y0 - dy * M; zIndex = Math.round(100 + M); fontSize = 8 + M * W * 2; color = "RGB("+c+","+c+","+c+")"; } } else { if(anim){ with(obj.style){ left = x0; top = y0; zIndex = 0; fontSize = 8; color = "RGB(88,88,88)"; } anim = false; } } } }}function run(){ for(i in o)o[i].mainloop(); setTimeout(run,16);}onload = function (){ DOOT = document.getElementById("doot"); with(DOOT.style){ left = -dim/2; top = -dim/2; width = dim; height = dim; } resize(); W = (dim / NX) / 2; H = (dim / NY) / 2; K = 0; for(var j=0;j<NY;j++){ for(var i=0;i<NX;i++){ c=T.charAt((I++)%T.length).toUpperCase(); if(c==" ")c="·"; o[K] = new CObj(K++,i,j,c); } } run();}//--></script></head><body><span style="position:absolute;left:50%;top:50%"> <span id="doot"></span></span></body></html>

小伙伴们想不想实现这种酷炫的效果，直接复制代码，运行即可，抓紧试试吧，或者是再来点创新。
