</SCRIPT>
写注册表:
<SCRIPT>
var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\", 1, "REG_BINARY");
WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader", "Goocher!", "REG_SZ");

TABLAE相关(客户端动态增加行列)
<HTML>
<SCRIPT LANGUAGE="JScript">
function numberCells() {

<TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR>
</TABLE>
</BODY>
</HTML>
1.身份证严格验证:
<script>
var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"}
function cidInfo(sId){
var iSum=0
var info=""
if(!/^\d{17}(\d|x)$/i.test(sId))return false;
sId=sId.replace(/x$/i,"a");
if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区";
sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2));
var d=new Date(sBirthday.replace(/-/g,"/"))
if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "Error:非法生日";
for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11)
if(iSum%11!=1)return "Error:非法证号";
return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女")
}
document.write(cidInfo("380524198002300016"),"<br/>");
document.write(cidInfo("340524198002300019"),"<br/>")
document.write(cidInfo("340524197711111111"),"<br/>")
document.write(cidInfo("34052419800101001x"),"<br/>");
</script>
2.验证IP地址
<SCRIPT LANGUAGE="java script">
function isip(s){
var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}};
var re=s.split(".")
return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false
}
var s="202.197.78.129";
alert(isip(s))
</SCRIPT>
3.加sp1后还能用的无边框窗口!!

电话号码的验证
要求:
(1)电话号码由数字、"("、")"和"-"构成
(2)电话号码为3到8位
(3)如果电话号码中包含有区号,那么区号为三位或四位
(4)区号用"("、")"或"-"和其他部分隔开
(5)移动电话号码为11或12位,如果为12位,那么第一位为0
(6)11位移动电话号码的第一位和第二位为"13"
(7)12位移动电话号码的第二位和第三位为"13"
根据这几条规则,可以与出以下正则表达式:
(^[0-9]{3,4}\-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)

alert(reg.test(str));
