表单验证是我们常用
手法
也是开发中经常用到代码不过今天说这段代码可能你没有写过哦那就是身份证号码和出生日期进行验证大家都知道从身份证上面可以得出该人出生日期我们将2个表单比对
下就可以得出该表单是否是乱填了整理www.好了不多说了起来看下面代码吧！ 
’CompareCodeAndSex’: varCode=vObj.value;
varSex=vCon.value;
varCodeSex;
(!vObj.disabled) {
(!vCon.disabled) {
(Code!=’’&&Sex!=’’) {
(Code.length
15) {
CodeSex=Code.substr(14,1);
(CodeSex1) {
CodeSex=’男’;
}
{
CodeSex=’女’;
} [Page]
(Sex!=CodeSex) {
eNum
; vObj.style.color=\"red\";
eMsg
genErrMsg(eNum,vObj,’身份证和性别不符！’); }
}
(Code.length18) {
CodeSex=Code.substr(16,1);
(CodeSex1) {
CodeSex=’男’;
}
[Page]{
CodeSex=’女’;
}
(Sex!=CodeSex) {
eNum
; vObj.style.color=\"red\";
eMsg
genErrMsg(eNum,vObj,’身份证和性别不符！’); }
}
}
}
}
; ’CompareCodeAndBirthday’: varCode=vObj.value;
varBirthday=vCon.value;
varYear;
varShortYear;
varMonth;
varDay;
varBYear; [Page]
(!vObj.disabled) {
(!vCon.disabled) {
(Code!=’’&&Birthday!=’’) {
(Code.length15) {
ShortYear=Code.substr(6,2);
Month=Code.substr(8,2);
Day=Code.substr(10,2);
ShortYear=ShortYear+Month+Day;
BYear=Birthday.substr(2,2);
Month=Birthday.substr(5,2);
Day=Birthday.substr(8,2);
BYear=BYear+Month+Day;
(ShortYear!=BYear) {
eNum
; vObj.style.color=\"red\";
eMsg
genErrMsg(eNum,vObj,’身份证和出生日期不符！’);
}
}
(Code.length18) {
Year=Code.substr(6,4); [Page]
Month=Code.substr(10,2);
Day=Code.substr(12,2);
Year=Year+Month+Day;
BYear=Birthday.substr(0,4);
Month=Birthday.substr(5,2);
Day=Birthday.substr(8,2);
BYear=BYear+Month+Day;
(Year!=BYear) {
eNum
; vObj.style.color=\"red\";
eMsg
genErrMsg(eNum,vObj,’身份证和出生日期不符！’); }
}
}
}
}
