3.8 文件上传过程中判断文件类型
<input type=file onchange="alert(this.value.match(/^(.*)(\.)(.{1,8})$/)[3])">
画图:
<object
id=s
style="left: 0px; width: 392px; top: 0px; height: 240px"
height=240
width=392
classid="clsid:369303c2-d7ac-11d0-89d5-00a0c90833e6">
</object>
<script>
s.drawingsurface.arcdegrees(0,0,0,30,50,60);
s.drawingsurface.arcradians(30,0,0,30,50,60);
s.drawingsurface.line(10,10,100,100);
</script>
写注册表：
<script>
var wshshell = wscript.createobject("wscript.shell");
wshshell.regwrite ("hkcu\\software\\acme\\fortuneteller\\", 1, "reg_binary");
wshshell.regwrite ("hkcu\\software\\acme\\fortuneteller\\mindreader", "goocher!", "reg_sz");
var bkey = wshshell.regread ("hkcu\\software\\acme\\fortuneteller\\");
wscript.echo (wshshell.regread ("hkcu\\software\\acme\\fortuneteller\\mindreader"));
wshshell.regdelete ("hkcu\\software\\acme\\fortuneteller\\mindreader");
wshshell.regdelete ("hkcu\\software\\acme\\fortuneteller\\");
wshshell.regdelete ("hkcu\\software\\acme\\");
</script>
tablae相关(客户端动态增加行列）
<html>
<script language="jscript">
function numbercells() {
var count=0;
for (i=0; i < document.all.mytable.rows.length; i++) {
for (j=0; j < document.all.mytable.rows(i).cells.length; j++) {
document.all.mytable.rows(i).cells(j).innertext = count;
count++;
}
}
}
</script>
<body onload="numbercells()">
<table id=mytable border=1>
<tr><th> </th><th> </th><th> </th><th> </th></tr>
<tr><td> </td><td> </td><td> </td><td> </td></tr>
<tr><td> </td><td> </td><td> </td><td> </td></tr>
</table>
</body>
</html>
１．身份证严格验证：
<script>
var acity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"}
function cidinfo(sid){
var isum=0
var info=""
if(!/^\d{17}(\d|x)$/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！！
