1。忽视右键
<body oncontextmenu="return false">
或
<body style="overflow-y:hidden">
2。加入背景音乐
IE:<bgsound src="*.mid" loop=infinite>
NS:<embed src="*.mid" autostart=true hidden=true loop=true>
</embed>
*.mid你的背景音乐的midi格式文件
3。简单的window.open方法
<a href="#"
onclick="javascript:window.open(文件路径/文件名,newwindow,
toolbar=no,scrollbars=yes,resizable=no,top=0,left=0,
width=400,height=300);">文字或图片</a>
参数解释:
<script LANGUAGE="javascript"> js脚本开始;
window.open 弹出新窗口的命令;
文件路径/文件名 弹出窗口的文件名;
newwindow 弹出窗口的名字(不是文件名),非必须,可用空代替;
width=400 窗口宽度;
height=300 窗口高度;
top=0 窗口距离屏幕上方的象素值;
left=0 窗口距离屏幕左侧的象素值;
toolbar=no 是否显示工具栏,yes为显示;
menubar,scrollbars 表示菜单栏和滚动栏。
resizable=no 是否允许改变窗口大小,yes为允许;
location=no 是否显示地址栏,yes为允许;
status=no 是否显示状态栏内的信息(通常是文件已经打开),yes为允许;
</SCRIPT> js脚本结束
4。简单的页面加密
<script LANGUAGE="javascript">
<!--
function loopy(){
var sWord ="";
while(sWord!="login"){sWord=prompt("请输入你的登陆密码");}
alert("登陆成功!");
}
loopy()
//-->
</script>
5。拉动页面时背景图不动
<style>
body{background-image:url(logo.gif);
background-repeat:no-repeat;background-position:center}
</style>
6。让浏览器在保存页面时保存失败
<NOSCRIPT><iframe src="*.html"></iframe></NOSCRIPT>
7。随机替换图片
<script>
document.write(<img src="img/+parseInt(Math.random()*(5))
+.gif"height="40" width="50">)
</script>
图片文件名为0.gif 1.gif 2.gif 3.gif 4.gif
8。窗口定时关闭
先将如下代码网页文件的区:
<script language="javascript">
function closeit() { setTimeout("self.close()",10000) //毫秒 }
</script>
然后再在<body>标内加入如:<body onload="closeit()">
9。网页自动关闭
<html>
<head>
<object id=closes type="application/x-oleobject"
classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="Command" value="Close">
</object>
</head>
<body onload="window.setTimeout(closes.Click(),10000)">
这个窗口会在10秒过后自动关闭,而且不会出现提示.
</body>
</html>
10。网页自动刷新
在head部记入
<META HTTP-EQUIV="Refresh" content="20">
其中20为20秒后自动刷新,你可以更改为任意值。
11。网页自动转页
<META HTTP-EQUIV="Refresh" CONTENT="时间(秒);URL=地址">
12。保持layer在最前面,而不被Iframe、Object所覆盖
在Layer中再插Iframe 或 Object 设z-Index值
<div z-Index:2><object xxx></object> # 前面
<div z-Index:1><object xxx></object> # 后面
<div id="Layer2" style="position:absolute; top:40;width:400px;
height:95px;z-index:2"> height=100% width=100%>
<iframe width=0 height=0></iframe>
</div>
<div id="Layer1" style="position:absolute; top:50;width:200px;
height:115px;z-index:1">
<iframe height=100% width=100%></iframe>
</div>
13。返回上一页
<a href=javascript:history.back(1)>『返回上一页』</a>
14。关闭窗口
<a href=javascript:self.close()>『关闭窗口』</a>
15。关于iframe的透明背景
<IFRAME ID="iFrame1" SRC="iframe.htm"
allowTransparency="true"
style="background-color: green"></IFRAME>
*******************************************************************************
('window.html','','width=394,height=290')弹出窗口
禁止页面正文选取
<body oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false"onmouseup="document.selection.empty()">
消除ie6自动出现的图像工具栏,设置 GALLERYIMG属性为false或no .
<IMG SRC="mypicture.jpg" HEIGHT="100px" WIDTH="100px" GALLERYIMG="no">
防止点击空链接时,页面往往重置到页首端。
代码“javascript:void(null)”代替原来的“#”标记
如何避免别人把你的网页放在框架中
<script language=“javascript”><!--if (self!=top){top.location=self.location;} -->< /script>
页面定时刷新
<meta http-equiv="Refresh" content="秒" >
页面定时转向新的地址
<meta http-equiv="refresh" content="秒;URL=url">
显示日期
<script language="javascript"><!--
today=new Date();
var week; var date;
if(today.getDay()==0) week="星期日"
if(today.getDay()==1) week="星期一"
if(today.getDay()==2) week="星期二"
if(today.getDay()==3) week="星期三"
if(today.getDay()==4) week="星期四"
if(today.getDay()==5) week="星期五"
if(today.getDay()==6) week="星期六"
date=(today.getYear())+"年"+(today.getMonth()+1)+"月"+today.getDate()+"日"+" "
document.write("<span style='font-size: 9pt;'>"+date+week+"</span>");
// -->
</script>
设为首页
<A href=# onclick="this.style.behavior='url(#default#homepage)';this.setHomePage('url');">设为首页</A>
添加收藏
<A href="javascript:window.external.AddFavorite('url','title')"> 加入收藏夹</A>
你谢我阿?难得哦~~我也有关闭窗口,这个是不会弹出提示直接关的:
把如下代码加入<body>区域中
<OBJECT id=closes type="application/x-oleobject" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="Command" value="Close">
</object>
<script language="javascript">function shutwin(){closes.Click();return;}</script>
<a href="javascript:shutwin();">关闭本窗口</a>
随机图片:
把如下代码加入<body>区域中
<script language="javascript"><!--
today=new Date();
jran=today.getTime();
function rnd() {
ia=9301;
ic=49297;
im=233280;
jran = (jran*ia+ic) % im;
return jran/(im*1.0);
};
function rand(number) {
return Math.ceil(rnd()*number);
};
document.write("<CENTER>");
for(i=1;i<=1;i++) {
myNum=(rand(10)); //改成你要随机显示的图片数;
if(myNum == 1) document.write("<img src='photo/back.jpg'>");
if(myNum == 2) document.write("<img src='photo/j2.gif'>"); //图片路径,可用http:// ;
if(myNum == 3) document.write("<img src='photo/email.gif'>");
if(myNum == 4) document.write("<img src='photo/arrow.gif'>");
if(myNum == 5) document.write("<img src='photo/j2.gif'>");
if(myNum == 6) document.write("<img src='photo/email.gif'>");
if(myNum == 7) document.write("<img src='photo/arrow.gif'>");
if(myNum == 8) document.write("<img src='photo/j2.gif'>");
if(myNum == 9) document.write("<img src='photo/back.jpg'>");
if(myNum == 10) document.write("<img src='photo/email.gif'>");
else {
document.write();
}
};
document.write("</CENTER>");
//-->
</script>
其实改一改随机什么都行,也不一定在body中
图片显隐效果
脚本说明:
把如下代码加入<body>区域中
<script language=javascript>
// Flash Image Extension for Dreamwever ,by Yichun Yuan(dezone@sina.com)
nereidFadeObjects = new Object();
nereidFadeTimers = new Object();
function nereidFade(object, destOp, rate, delta){
if (!document.all)
return
if (object != "[object]"){ //do this so I can take a string too
setTimeout("nereidFade("+object+","+destOp+","+rate+","+delta+")",0);
return;
}
clearTimeout(nereidFadeTimers[object.sourceIndex]);
diff = destOp-object.filters.alpha.opacity;
direction = 1;
if (object.filters.alpha.opacity > destOp){
direction = -1;
}
delta=Math.min(direction*diff,delta);
object.filters.alpha.opacity+=direction*delta;
if (object.filters.alpha.opacity != destOp){
nereidFadeObjects[object.sourceIndex]=object;
nereidFadeTimers[object.sourceIndex]=setTimeout("nereidFade(nereidFadeObjects["+object.sourceIndex+"],"+destOp+","+rate+","+delta+")",rate);
}
}
</script>
<a href=#><img src="photoshopcn.jpg" border=0 onMouseOut=nereidFade(this,50,10,5) onMouseOver=nereidFade(this,100,10,5) style="FILTER: alpha(opacity=40)"></a>
