广告招租，e-mail:yesize@hotmail.com 1、随机广告 <SCRIPT LANGUAGE=JavaScript> <!-- Begin var how_many_ads = 3; var now = new Date() var sec = now.getSeconds() var ad = sec % how_many_ads; ad +=1; if (ad==1) { txt=The Worlds Largest Online Bookstore, Amazon.com; url=http://www.amazon.com; alt=amazon.com; banner=http://imageserv.imgis.com/images/Ad12669St1Sz1Sq1_Ban1.gif; width=468; height=60; } if (ad==2) { txt=Palm III by 3Com, in stock!; url=http://cybershop.com/; alt=cybershop.com; banner=http://imageserv.imgis.com/images/Ad13189St1Sz1Sq5_Ban10.gif; width=468; height=60; } if (ad==3) { txt=Find it at GoTo.com; url=http://www.goto.com; alt=goto.com; banner=http://imageserv.imgis.com/images/Ad13700St1Sz1Sq1_Ban1.gif; width=468; height=60; } document.write(<center>); document.write(<a href=\ + url + \ target=\_top\>); document.write(<img src=\ + banner + \ width=) document.write(width + height= + height + ); document.write(alt=\ + alt + \ border=0> ); document.write(<small> + txt + </small></a>); document.write(</center>); // End --> </SCRIPT> 2、随机背景颜色 <HTML> <HEAD> <TITLE>Random Background</TITLE> <SCRIPT LANGUAGE=JavaScript> <!-- function backcolor(form) { temp = for (var i = 0; i < 16; i++) { temp = form.color[i].value if (form.color[i].checked){ document.bgColor = temp } } } function randombackground() { document.bgColor = getColor() } function getColor(){ currentdate = new Date() backgroundcolor = currentdate.getSeconds() if (backgroundcolor > 44) backgroundcolor = backgroundcolor - 45 else if (backgroundcolor > 29) backgroundcolor = backgroundcolor - 30 else if (backgroundcolor > 15) backgroundcolor = backgroundcolor - 16 if (backgroundcolor == 0 ) return olive; else if (backgroundcolor == 1 ) return teal; else if (backgroundcolor == 2 ) return red; else if (backgroundcolor == 3 ) return blue; else if (backgroundcolor == 4 ) return maroon; else if (backgroundcolor == 5 ) return navy; else if (backgroundcolor == 6 ) return lime; else if (backgroundcolor == 7 ) return fuschia; else if (backgroundcolor == 8 ) return green; else if (backgroundcolor == 9 ) return purple; else if (backgroundcolor == 10 ) return gray; else if (backgroundcolor == 11 ) return yellow; else if (backgroundcolor == 12 ) return aqua; else if (backgroundcolor == 13 ) return black; else if (backgroundcolor == 14 ) return white; else if (backgroundcolor == 15 ) return silver; } // End --> </SCRIPT> </HEAD> <BODY BGCOLOR=#ffffff vlink=#0000ff> <CENTER> <FORM> <input type=button value=随机背景颜色 onClick=randombackground()> </FORM> </CENTER> </body></html> 3、随机背景图案 <HTML> <HEAD> <TITLE>Random Images</TITLE> <SCRIPT LANGUAGE=JavaScript> today=new Date(); jran=today.getTime(); var number = 3; var random_number=; var image=; var text_color=; ia=9301; ic=49297; im=233280; jran = (jran*ia+ic) % im; random_number = Math.ceil( (jran/(im*1.0)) *number); if (random_number==1) { text_color=000000; image=bg1.gif; } if (random_number==2) { text_color=000000; image=bg2.jpg; } if (random_number==3) { text_color=000000; image=bg3.gif; } // End --> </SCRIPT> </HEAD> <SCRIPT LANGUAGE=JavaScript> <!-- Begin document.open(); document.write(<BODY BACKGROUND=+image+ TEXT=+text_color+ vlink=#0000ff>); document.write(<CENTER></CENTER>); // End --> </SCRIPT> <FORM> <INPUT TYPE=button VALUE=Reload Page onClick=window.location=RandomBgImages.htm> </FORM> <SCRIPT LANGUAGE=JavaScript> <!-- Begin document.write(<CENTER><FONT SIZE=-1 color=red>Background Image: (+image+)</FONT></CENTER>); // End --> </SCRIPT> </body></html> 4、随机图案 把以下代码放在<head></head>之间： <script language=JavaScript> a = 4 var slump = Math.random(); var talet = Math.round(slump * (a-1))+1; function create() { this.src = this.border = this.alt = } b = new Array() for(var i=1; i<=a; i++) { b[i] = new create() } b[1].src = reset.gif b[1].border = 0 b[1].alt = 111 b[2].src = back.gif b[2].border = 0 b[2].alt = 222 b[3].src = ie.gif b[3].border = 0 b[3].alt = 333 b[4].src = netscape.gif b[4].border = 0 b[4].alt = 444 var visa = ; visa += <img src=+b[talet].src+ border=0+ alt=+b[talet].alt+>; </SCRIPT> 把以下代码放在HTML文件任意地方： <script language=JavaScript> <!-- Hide this script from old browsers -- document.write(visa) // --> </script> 5、随机播放MIDI音乐 把以下代码放在<head></head>之间： <script language=JavaScript> <!--Hide from non JavaScript browsers am = 5 var ran = Math.random(); var talet = Math.round(ran * (am-1))+1; function create() { this.src = } c = new Array() for(var i=1; i<=am; i++) { c[i] = new create() } c[1].src = hh1.mid c[2].src = hh2.mid c[3].src = hh3.mid c[4].src = hh4.mid c[5].src = hh5.mid var vismid = ; vismid += <embed src=+c[talet].src+ width=0 height=0+ autostart=true+ loop=2+>; //--> </SCRIPT> 把以下代码放在<body></body>之间： <script language=JavaScript> <!--Hide from non JavaScript browsers document.write(vismid); //--> </script> 6、随机文本 把以下代码放在<head></head>之间： <script language=JavaScript> <!-- Hide var a = Math.random() + var rand1 = a.charAt(5) quotes = new Array quotes[1] = MESSAGE #1 quotes[2] = MESSAGE #2 quotes[3] = MESSAGE #3 quotes[4] = MESSAGE #4 quotes[5] = MESSAGE #5 quotes[6] = MESSAGE #6 quotes[7] = MESSAGE #7 quotes[8] = MESSAGE #8 quotes[9] = MESSAGE #9 quotes[0] = MESSAGE #10 var quote = quotes[rand1] // --> </script> 把以下代码放在HTML文件任意地方： <script language=JavaScript> <!-- Hide document.write(<i> + quote + </i>) // --> </script> 7、随机连接 把以下代码放在<head></head>之间： <script language=JavaScript> <!--Hide from non JavaScript browsers an = 5 var ran = Math.random(); var talet = Math.round(ran * (an-1))+1; function create() { this.src = } b = new Array() for(var i=1; i<=an; i++) { b[i] = new create() } b[1].src = <a href=http://netscape.yahoo.com/guide/Whats_cool.html> b[2].src = <a href=http://www.disney.com> b[3].src = <a href=http://www.peoplelink.com/> b[4].src = <a href=http://www.china-contact.com/cool/interest.htm> b[5].src = <a href=HTTP://www.homeway.com.cn/html/homeway/navigator/index.html> var vis = ; vis += b[talet].src; //--> </SCRIPT> 把以下代码放在<body></body>之间： <script language=JavaScript> <!--Hide from non JavaScript browsers document.write(vis+random link+</a>); //--> </SCRIPT>
