代码如下:

//[Step1]: 在此能够设置雨滴的多少var rainsize = 80;//[Step2]: 这里可以更改下雨的速度，数值大速度慢var speed = 110;var x = new Array();var y = new Array();var r = new Array();var cx = new Array();var cy = new Array();var doc_width = document.body.clientWidth;var doc_height = document.body.clientHeight;for(i=0; i<rainsize; ++i) {initRain();if (i == 0) {document.write("<div id=\"dot"+ i+"\" style=\"POSITION: ");document.write("absolute; Z-INDEX: "+ i +"; VISIBILITY: ");document.write("visible; TOP: 15px; LEFT: 15px;\">");document.write(",</div>");}else {document.write("<div id=\"dot"+ i+"\" style=\"POSITION: ");document.write("absolute; Z-INDEX: "+ i +"; VISIBILITY: ");document.write("visible; TOP: 15px; LEFT: 15px;\">");document.write(",.</div>"); }}function initRain() {a = 6;r[i] = 1;sn = Math.sin(a);cs = Math.cos(a);cx[i] = Math.random() * doc_width + 1;cy[i] = Math.random() * doc_height + 1;x[i] = r[i] * sn + cx[i];y[i] = cy[i];}function raindropIE() {for (i = 0; i < rainsize; ++ i) {updateRain();if ((x[i] <= 1) || (x[i] >= (doc_width- 20)) || (y[i] >= (doc_height - 20))){makeRain();doc_width = document.body.clientWidth;doc_height = document.body.clientHeight; }document.all["dot"+i].style.pixelTop = y[i];document.all["dot"+i].style.pixelLeft = x[i]; }setTimeout("raindropIE()", speed);}function updateRain() {r[i] += 10;x[i] = r[i] * sn + cx[i];y[i] = r[i] * cs + cy[i];}function makeRain() {r[i] = 1;cx[i] = Math.random() * doc_width + 1;cy[i] = 1;x[i] = r[i] * sn + cx[i];y[i] = r[i] * cs + cy[i];}raindropIE();var caution = falsefunction setCookie(name, value, expires, path, domain, secure) {var curCookie = name + "=" + escape(value) +((expires) ?
