可以很大的加大的网站的访问量。

二、在网页中的 标记中加入下面的代码:

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>
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"
}
}
