1、随机产生文本，刷新网页即可显示随机效果。
程序代码：

您最喜欢中国的哪个城市：
<script language="JavaScript">
<!--
var a = Math.random() + ""
var rand1 = a.charAt(5)
quotes = new Array
quotes[1] = '北京'
quotes[2] = '上海'
quotes[3] = '广州'
quotes[4] = '哈尔滨'
quotes[5] = '长春'
quotes[6] = '武汉'
quotes[7] = '沈阳'
quotes[8] = '大连'
quotes[9] = '呼和浩特'
quotes[0] = '成都'
var quote = quotes[rand1]
document.write( quote )
// -->

49、检查显示分辨率。
程序代码：

<script language="JavaScript">
<!--
var correctwidth=1024
var correctheight=768
if (screen.width!=correctwidth||screen.height!=correctheight)

document.write("本站最佳分辨率: "+correctwidth+"*"+correctheight+". 您当前的分辨率是:"+screen.width+"*"+screen.height+"。<br><br>设置合适的分辨率才能取得最佳的显示效果！")
else
document.write("您当前的分辨率是:"+screen.width+"*"+screen.height+"。<br><br>您的浏览器符合浏览本网站的要求！")
//-->
</script>

50、检测IE所安装的插件。
程序代码：

<script language="JavaScript">
<!--

 var pluginsnum = navigator.plugins.length;

for (var i=0; i < pluginsnum; i++) {
   var number=i+1;
   document.write("<font color=red>Plug-in No." + number + "- </font>"+navigator.plugins[i].name+" <br>[Location: " + navigator.plugins[i].filename + "]<p>");
   }
if (number == undefined)                    

    alert ("\n多找一些外挂程序吧! 目前您还没有外挂程序!")
elseif (number>0)
        alert("\n你有 " + number + " 种外挂程序!")

51、检测点链接速度。
程序代码：

<script language="JavaScript">
<!--
tim=1
setInterval("tim++",100)
b=1

var geturl=new Array()      

geturl[1]="www.hlju.[2]="www.[3]="www.[4]="www.moe.[5]="www.("<form name=autof>")
for(var i=1;i<geturl.length;i++)
document.write("<input type=text name=txt"+i+" size=10 value=测试中……> =>> <input type=text name=url"+i+" size=40> =>> <input type=button value=点击进入网站 onclick=window.open(this.form.url"+i+".value)><br>")

function auto(url){
document.forms[0]["url"+b].value=url               

if(tim>200)
{document.forms[0]["txt"+b].value="链接超时"}         

else
{document.forms[0]["txt"+b].value="时间"+tim/10+"秒"}   

b++
}
for(var i=1;i<geturl.length;i++)            

document.write("<img src=http://"+geturl[i]+"/"+Math.random()+" width=1 height=1 onerror=auto('http://"+geturl[i]+"')>")
//-->
</script>

以上是检测黑龙江大学网站、网易163网站、新浪网站、教育部网站、中央电视台网站的链接速度。
