判断是否为邮政编码
function f_check_zipcode(obj)
{
if(!f_check_number(obj))
return false;
if(obj.value.length!=6)
{
f_alert(obj,"邮政编码长度必须是6位");
return false;
}
return true;
}
用户ID,可以为数字、字母、下划线的组合,
第一个字符不能为数字,且总长度不能超过20。
function f_check_userID(obj)
{
var userID = obj.value;
if(userID.length > 20)
{
f_alert(obj,"ID长度不能大于20");
return false;
}
if(!isNaN(userID.charAt(0)))
{
f_alert(obj,"ID第一个字符不能为数字");
return false;
}
if(!/^\w{1,20}$/.test(userID))
{
f_alert(obj,"ID只能由数字、字母、下划线组合而成");
return false;
}
return true;
}
功能:验证身份证号码是否有效
提示信息:未输入或输入身份证号不正确!
使用:f_check_IDno(obj)
返回:bool
function f_check_IDno(obj)
{
var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"};
var iSum = 0;
var info = "";
var strIDno = obj.value;
var idCardLength = strIDno.length;
if(!/^\d{17}(\d|x)$/i.test(strIDno)&&!/^\d{15}$/i.test(strIDno))
{
f_alert(obj,"非法身份证号");
return false;
}
//在后面的运算中x相当于数字10,所以转换成a
strIDno = strIDno.replace(/x$/i,"a");
if(aCity[parseInt(strIDno.substr(0,2))]==null)
{
f_alert(obj,"非法地区");
return false;
}
if (idCardLength==18)
{
sBirthday=strIDno.substr(6,4)+"-"+Number(strIDno.substr(10,2))+"-"+Number(strIDno.substr(12,2));
var d = new Date(sBirthday.replace(/-/g,"/"))
if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))
{
f_alert(obj,"非法生日");
return false;
}
for(var i = 17;i>=0;i --)
iSum += (Math.pow(2,i) % 11) * parseInt(strIDno.charAt(17 - i),11);
if(iSum%11!=1)
{
f_alert(obj,"非法身份证号");
return false;
}
}
else if (idCardLength==15)
{
sBirthday = "19" + strIDno.substr(6,2) + "-" + Number(strIDno.substr(8,2)) + "-" + Number(strIDno.substr(10,2));
var d = new Date(sBirthday.replace(/-/g,"/"))
var dd = d.getFullYear().toString() + "-" + (d.getMonth()+1) + "-" + d.getDate();
if(sBirthday != dd)
{

return false;
