网页下雪特效代码(html下雨特效代码)
请问网页下雪或者是往下飘花瓣特效是什么代码啊
那个可以用flash来实现，在你的网页上放一个下雪的flash，背景设为透明，z-index设高一点，就可以实现这样的效果了。网上找找吧，很多的。
希望对你有帮助~
求网页飘雪花源代码
把下列代码加到网页的Body/Body标签之间

记得给我加分啊
var snowsrc="images/xuehua1.gif"这句是你雪花图片的地址
如何用FLASH制作下雪特效
第一层添加一个图片，再添加一个图层，添加空白关键帧，打开动作，把脚本放上去！脚本如下： FLSHA下雪效果脚本fallSnow(this, 100, [550, 400]);
function fallSnow(path, num, size) {
for (var i = 0; inum; i++) {
path.createEmptyMovieClip("s"+i, i);
var mc = path["s"+i];
mc._x = random(size[0]);
mc._y = random(size[1]);
mc.ro = [1, -1][random(2)];
mc.xtime = random(20);
mc.startTime = 0;
mc.id = Math.pow(i, 1/2);
createSnow(mc, mc.id/2.5, "0xffffff", 20*mc.id);
}
var loop = function () {
updateAfterEvent();
for (var i = 0; inum; i++) {
var mc = path["s"+i];
mc._rotation += mc.ro*5;
mc._x += mc.id*mc.ro/10;
mc._y += mc.id/2;
mc.startTime++;
scanTar(mc);
scanEdge(mc, size);
}
};
var interval = setInterval(loop, 10);
}
function createSnow(mc, radius, c, alpha) {
with (mc) {
moveTo(0, -radius);
beginFill(c, alpha);
lineStyle(0, "0x000000", 0);
for (var i = 1; i=6; i++) {
var a1 = -Math.PI/6+i*Math.PI/3;
var a2 = i*Math.PI/3;
lineTo((radius/5)*Math.sin(a1), -(radius/5)*Math.cos(a1));
lineTo(radius*Math.sin(a2), -radius*Math.cos(a2));
}
endFill();
}
}
function scanTar(mc) {
if (mc.startTime=mc.xtime) {
mc.startTime = 0;
mc.xtime = random(20);
mc.ro = [1, -1][random(2)];
}
}
function scanEdge(mc, size) {
if (mc._xsize[0]) {
mc._x = 0;
} else if (mc._x0) {
mc._x = size[0];
}
if (mc._ysize[1]) {
mc._y = 0;
}
}
请教网页飘雪的插景，布满整个页面（不是背景）怎么制作
点击编辑窗口左下角的“HTML”选项卡，即出现源代码窗口，将特效代码粘贴进去即可。
这里有代码~
