列出些常用的javascript,大家可以把这些做成一个类,方便在项目中重复的调用。
至于怎么做,Blog已有介绍,我就不多说了。
欢迎大家补充^_^
1.让文字不停地滚动
<MARQUEE>滚动文字</MARQUEE>
2.记录并显示网页的最后修改时间
<script language=javascript> document.write("最后更新时间: " + document.lastModified + "") </script>
3.关闭当前窗口
<a href="/"onClick="javascript:window.close();return false;">关闭窗口</a>
4.5秒后关闭当前页
<script language="javascript"> <!-- setTimeout(''window.close();'',5000); --> </script>
5.2秒后载入指定网页
<head> <meta http-equiv="refresh" content="2;URL=http://你的网址"> </head>
6.添加到收藏夹
<Script Language="javascript"> function bookmarkit() { window.external.addFavorite(''http://你的网址'',''你的网站名称'') } if (document.all)document.write(''<a href="#" onClick="bookmarkit()">加入收藏夹</a>'') </Script>
7.让超链接不显示下划线
<style type="text/css"> <!- a:link{text-decoration:none} a:hover{text-decoration:none} a:visited{text-decoration:none} -> </style>
8.禁止鼠标右键的动作
<Script Language = "javascript"> function click() { if (event.button==2||event.button==3) { alert(''禁止鼠标右键''); } document.onmousedown=click // --> </Script>
9.设置该页为首页
<body bgcolor="#FFFFFF" text="#000000"> <!-- 网址:http://你的网址--> <a class="chlnk" style="cursor:hand" HREF onClick="this.style.behavior=''url(#default#homepage)''; this.setHomePage(''你的网站名称);"><font color="000000" size="2" face="宋体">设为首页</font></a> </body>
10.节日倒计时
<Script Language="javascript"> var timedate= new Date("December 25,2003"); var times="圣诞节"; var now = new Date(); var date = timedate.getTime() - now.getTime(); var time = Math.floor(date / (1000 * 60 * 60 * 24)); if (time >= 0) document.write("现在离"+times+"还有: "+time +"天")</Script>
11.单击按钮打印出当前页
<Script Language="javascript"> <!-- Begin if (window.print) { document.write(''<form>'' + ''<input type=button name=print value="打印本页" '' + ''onClick="javascript:window.print()"></form>''); } // End --> </Script>
12.单击按钮‘另存为’当前页
<input type="button" name="Button" value="保存本页" onClick="document.all.button.ExecWB(4,1)"> <object id="button" width=0 height=0 classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"> <embed width="0" height="0"></embed> </object>
13.显示系统当前日期
<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: 宋体''> ", today.getYear(),"年",today.getMonth()+1,"月",today.getDate(),"日", d[today.getDay()+1],"</font>" ); </script>
14.不同时间段显示不同问候语
<Script Language="javascript"> <!-- var text=""; day = new Date( ); time = day.getHours( ); if (( time>=0) && (time < 7 )) text="夜猫子,要注意身体哦! " if (( time >= 7 ) && (time < 12)) text="今天天气……哈哈哈,不去玩吗?" if (( time >= 12) && (time < 14)) text="午休时间哦,朋友一定是不习惯午睡的吧?!" if (( time >=14) && (time < 18)) text="下午茶的时间到了,休息一下吧! " if ((time >= 18) && (time <= 22)) text="您又来了,可别和MM聊太久哦!" if ((time >= 22) && (time < 24)) text="很晚了哦,注意休息呀!" document.write(text) //---> </Script>
15.水中倒影效果
<img id="reflect" src="你自己的图片文件名" width="175" height="59"> <script language="javascript"> function f1() { setInterval("mdiv.filters.wave.phase+=10",100); } if (document.all) { document.write(''<img id=mdiv src="''+document.all.reflect.src+''" style="filter:wave(strength=3,freq=3,phase=0,lightstrength=30) blur() flipv()">'') window.onload=f1 } </script>
16.慢慢变大的窗口
<Script Language="javascript"> <!-- var Windowsheight=100 var Windowswidth=100 var numx=5 function openwindow(thelocation){ temploc=thelocation if (!(window.resizeTo&&document.all)&&!(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)">进入</a>
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">
