17．改變IE地址欄的IE圖標(biāo)
我們要先做一個(gè)16*16的icon（圖標(biāo)文件），保存為index.ico。把這個(gè)圖標(biāo)文件上傳到根目錄下并在首頁＜head＞＜/head＞之間加上如下代碼：

?。?script＞
＜/body＞
20．離開網(wǎng)頁時(shí)和加載網(wǎng)站時(shí)提示你將本站加入收藏夾
可以很大的加大的網(wǎng)站的訪問量。
一、在網(wǎng)頁的
二、在網(wǎng)頁中的 標(biāo)記中加入下面的代碼：
onunload=favorate()
當(dāng)然如果你想在網(wǎng)頁載入時(shí)提示只需要把
上面的onunload=favorate()改成onload=favorate()
21．JS制作網(wǎng)頁標(biāo)題欄滾動(dòng)信息的顯示:
將下面的代碼copy到網(wǎng)頁的<head>和</head>中.
<SCRIPT LANGUAGE=JAVASCRIPT>
<!--
var msg = "藍(lán)色空間";
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>
在網(wǎng)頁的BODY中加入下面的代碼:
<BODY onload="window.setTimeout('titleScroll()', 500)">
22．JS狀態(tài)欄信息分行顯示:
將下面的代碼copy到網(wǎng)頁的<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] = "藍(lán)色空間";
ar[1] = "歡迎你的光臨";
ar[2] = "有建議請(qǐng)聯(lián)系V-藍(lán)動(dòng)力";
-->
</SCRIPT>
在網(wǎng)頁的BODY中加入下面的代碼:
<BODY onload=startBanner()>
23. 可以在收藏夾中顯示出你的圖標(biāo)
<link rel="Bookmark" href="favicon.ico">
24. 永遠(yuǎn)都會(huì)帶著框架
<script language="javascript"><!--
if (window == top)top.location.href = "frames.htm"; //frames.htm為框架網(wǎng)頁
// --></script>
25. 最小化、最大化、關(guān)閉窗口
<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=關(guān)閉 onclick=hh3.Click()>
本例適用于IE
26. TEXTAREA自適應(yīng)文字行數(shù)的多少
<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight">
</textarea>
27. 檢測(cè)某個(gè)網(wǎng)站的鏈接速度：
把如下代碼加入<body>區(qū)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=測(cè)試中……> =》<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="鏈接超時(shí)"}
else
{document.forms[0]["txt"+b].value="時(shí)間"+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. 如何改變鏈接的鼠標(biāo)形狀
只需在鏈接上加上這一代碼就行的了
或者跟上面的用CSS寫也行
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"
以上代碼你只需要加到連接或是頁面的STYLE區(qū)里就可以實(shí)現(xiàn)鼠標(biāo)多樣化。
29.COOKIE腳本記錄，有很大的用處。
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"
}
}
說明：以上是JS代碼，請(qǐng)自己加起始符和結(jié)束符
