列出些常用的javascript，大家可以把這些做成一個(gè)類，方便在項(xiàng)目中重復(fù)的調(diào)用。

3．關(guān)閉當(dāng)前窗口
<a href="/"onClick="javascript：window.close();return false;">關(guān)閉窗口</a>
4．5秒后關(guān)閉當(dāng)前頁(yè)
<!-- setTimeout(''window.close();'',5000); -->
5．2秒后載入指定網(wǎng)頁(yè)
<head> <meta http-equiv="refresh" content="2;URL=http://你的網(wǎng)址"> </head>
6．添加到收藏夾
function bookmarkit() {
window.external.addFavorite(''http://你的網(wǎng)址'',''你的網(wǎng)站名稱'')
}
if (document．a(chǎn)ll)

7．讓超鏈接不顯示下劃線

function click() {
if (event.button==2||event.button==3) {
alert(''禁止鼠標(biāo)右鍵'');
}
document．onmousedown=click // -->
9．設(shè)置該頁(yè)為首頁(yè)
<body bgcolor="#FFFFFF" text="#000000"> <!-- 網(wǎng)址：http://你的網(wǎng)址-->
<a class="chlnk" style="cursor:hand" HREF onClick="this.style.behavior=''url(#default#homepage)''; this.setHomePage(''你的網(wǎng)站名稱);"><font color="000000" size="2" face="宋體">設(shè)為首頁(yè)</font></a>

var date = timedate.getTime() - now.getTime();
var time = Math.floor(date / (1000 * 60 * 60 * 24));
if (time >= 0)
document．write("現(xiàn)在離"+times+"還有: "+time +"天")
</Script>

</Script>
12．單擊按鈕‘另存為’當(dāng)前頁(yè)
<input type="button" name="Button" value="保存本頁(yè)" onClick="document．a(chǎn)ll.button.ExecWB(4,1)">

13．顯示系統(tǒng)當(dāng)前日期
<script language=javascript>
today=new Date();
function date(){
this.length=date.arguments.length
for(var i=0;i<this.length;i++)
this[i+1]=date.arguments
}
var d=new date("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
document．write( "<font color=##000000 style=''font-size:9pt;font-family: 宋體''> ",

d[today.getDay()+1],"</font>" ); </script>
14．不同時(shí)間段顯示不同問(wèn)候語(yǔ)
<Script Language="javascript">

if (document．a(chǎn)ll) {
document．write(''<img id=mdiv src="''+document．a(chǎn)ll.reflect.src+''"

16．慢慢變大的窗口
<Script Language="javascript">
<!-- var Windowsheight=100
var Windowswidth=100
var numx=5
function openwindow(thelocation){
temploc=thelocation
if (!(window.resizeTo&&document．a(chǎn)ll)&&!(window.resizeTo&&document．getElementById)) {
window.open(thelocation)
return }
windowsize=window.open("","","scrollbars")
windowsize.moveTo(0,0)
windowsize.resizeTo(100,100)
tenumxt() }
function tenumxt(){
if (Windowsheight>=screen.availHeight-3)
numx=0
windowsize.resizeBy(5,numx)
Windowsheight+=5
Windowswidth+=5
if (Windowswidth>=screen.width-5) {
windowsize.location=temploc
Windowsheight=100
Windowswidth=100
numx=5
return
}
setTimeout("tenumxt()",50)
}
//-->
</script>
<p><a href="javascript：openwindow( http://www.xxx.com )">進(jìn)入</a>
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(yè)<head></head>之間加上如下代碼： <link REL = "Shortcut Icon" href="/index.ico">
