17.改变IE地址栏的IE图标

  我们要先做一个16*16的icon(图标文件),保存为index.ico。把这个图标文件上传到根目录下并在首页<head></head>之间加上如下代码:

          <link REL = "Shortcut Icon" href="index.ico">

18.鼠标指向时弹出信息框

  <body>

  <a href onmouseover="alert('弹出信息!')">显示的链接文字</a>

       </body>

19.单击鼠标右键弹出添加收藏夹对话框

  <body>

  <script Language=javascript>

  if (document.all)

  document.body.onmousedown=new function("if (event.button==2||event.button==3)

  window.external.addFavorite('您的网址','您的网站名称)")

  </script>

        </body>

20.离开网页时和加载网站时提示你将本站加入收藏夹

可以很大的加大的网站的访问量。

一、在网页的

二、在网页中的 标记中加入下面的代码:

onunload=favorate()

当然如果你想在网页载入时提示只需要把

上面的onunload=favorate()改成onload=favorate()

21.JS制作网页标题栏滚动信息的显示:

将下面的代码copy到网页的<head>和</head>中.

<SCRIPT LANGUAGE=JAVASCRIPT>

<!--

var msg = "蓝色空间";

var speed = 300;

var msgud = " " + msg;

function titleScroll() {

if (msgud.length msgud = msgud.substring(1, msgud.length);

document.title = msgud.substring(0, msg.length);

window.setTimeout("titleScroll()", speed);

}

-->

</SCRIPT>

在网页的BODY中加入下面的代码:

<BODY onload="window.setTimeout('titleScroll()', 500)">

22.JS状态栏信息分行显示:

将下面的代码copy到网页的<head>和</head>中.

<SCRIPT LANGUAGE=JAVASCRIPT>

<!--

function makeArray(n) {

this.length = n;

}

function stopBanner() {

if (bannerRunning)

clearTimeout(timerID);

bannerRunning = false;

}

function startBanner() {

stopBanner();

showBanner();

} function showBanner() {

var text = ar[currentMessage];

if (offset < text.length) {

if (text.charAt(offset) == " ")

offset++;

var partialMessage = text.substring(0, offset + 1);

window.status = partialMessage;

offset++;

timerID = setTimeout("showBanner()", speed);

bannerRunning = true;

} else {

offset = 0;

currentMessage++;

if (currentMessage == arlength)

currentMessage = 0;

timerID = setTimeout("showBanner()", pause);

bannerRunning = true;

}

}

var speed = 100

var pause = 1000

var timerID = null;

var bannerRunning = false;

var currentMessage = 0;

var offset = 0;

var arlength = 3;

var ar = new makeArray(arlength);

ar[0] = "蓝色空间";

ar[1] = "欢迎你的光临";

ar[2] = "有建议请联系V-蓝动力";

-->

</SCRIPT>

在网页的BODY中加入下面的代码:

<BODY onload=startBanner()>

23. 可以在收藏夹中显示出你的图标

      <link rel="Bookmark" href="favicon.ico">

24. 永远都会带着框架

<script language="javascript"><!--

if (window == top)top.location.href = "frames.htm"; //frames.htm为框架网页

// --></script>

25. 最小化、最大化、关闭窗口

<object id=hh1 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">

<param name="Command" value="Minimize"></object>

<object id=hh2 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">

<param name="Command" value="Maximize"></object>

<OBJECT id=hh3 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">

<PARAM NAME="Command" value="Close"></OBJECT>

<input type=button value=最小化 onclick=hh1.Click()>

<input type=button value=最大化 onclick=hh2.Click()>

<input type=button value=关闭 onclick=hh3.Click()>

本例适用于IE

26. TEXTAREA自适应文字行数的多少

<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight">

</textarea>

27. 检测某个网站的链接速度:

把如下代码加入<body>区域中:

<script language=javascript>

tim=1

setInterval("tim++",100)

b=1

var autourl=new Array()

autourl[1]="www.njcatv.net"

autourl[2]="javacool.3322.net"

autourl[3]="www.sina.com.cn"

autourl[4]="www.nuaa.edu.cn"

autourl[5]="www.cctv.com"

function butt(){

document.write("<form name=autof>")

for(var i=1;i<autourl.length;i++)

document.write("<input type=text name=txt"+i+" size=10 value=测试中……> =》<input type=text name=url"+i+" size=40> =》<input type=button value=GO onclick=window.open(this.form.url"+i+".value)><br/>")

document.write("<input type=submit value=刷新></form>")

}

butt()

function auto(url){

document.forms[0]["url"+b].value=url

if(tim>200)

{document.forms[0]["txt"+b].value="链接超时"}

else

{document.forms[0]["txt"+b].value="时间"+tim/10+"秒"}

b++

}

function run(){for(var i=1;i<autourl.length;i++)document.write("<img src=http://"+autourl[i]+"/"+Math.random()+" width=1 height=1 onerror=auto( http://";;+autourl[i]+"')>")}

run()</script>

28. 如何改变链接的鼠标形状

只需在链接上加上这一代码就行的了

或者跟上面的用CSS写也行

style="cursor:hand"       style="cursor:crosshair"

style="cursor:text"       style="cursor:wait"

style="cursor:move"       style="cursor:help"

style="cursor:e-resize"     style="cursor:n-resize"

style="cursor:nw-resize"     style="cursor:w-resize"

style="cursor:s-resize"     style="cursor:se-resize"

style="cursor:sw-resize"

以上代码你只需要加到连接或是页面的STYLE区里就可以实现鼠标多样化。

29.COOKIE脚本记录,有很大的用处。

function get_cookie(Name) {

var search = Name + "="

var returnvalue = "";

if (documents.cookie.length > 0) {

offset = documents.cookie.indexOf(search)

if (offset != -1) { // if cookie exists

offset += search.length

// set index of beginning of value

end = documents.cookie.indexOf(";", offset);

// set index of end of cookie value

if (end == -1)

end = documents.cookie.length;

returnvalue=unescape(documents.cookie.substring(offset, end))

}

}

return returnvalue;

}

function loadpopup(){

if (get_cookie('popped')==''){

openpopup()

documents.cookie="popped=yes"

}

}

说明:以上是JS代码,请自己加起始符和结束符
