我想从出生之日起就知道一个人的年龄.我有一个HTML代码,我正在使用dob的datepicker,当我给出生日期时,它显示自动显示年龄而不提交.请帮我找到解决方案.

CDateArr = ('' + Cdate).split(" ");
Age = CDateArr[3] …您好我无法得到正确的验证.我认为此代码中存在一些错误,所以任何人都可以帮我解决这个问题.
public static boolean validateFee(String value) {
boolean isvalid = true;
try {
int fee = 0;
if (value != null && !value.isEmpty()) {
fee = Integer.parseInt(value);
}
} catch (NumberFormatException ne) {
// ne.printStackTrace();
isvalid = false;
return isvalid;
}
return isvalid;
}
}
我正在使用此代码验证费用,其中使用正则表达式作为[0-9] +.这段代码我在一个公共函数中使用它.实际上验证调用是在servlet中完成的,如下所示:
private Boolean validateFee(HttpSession session, PropertiesHandler props, String number) {
Boolean isvalid = true;
HashMap hashMap = new LinkedHashMap();
number = ApplicationConstants.FEE_PATTERN;
if (!Validation.validateFee(number)) {
isvalid = false;
hashMap.put("time", props.getText("error.fee.invalid.type"));
}
session.setAttribute("errorMessage", hashMap);
System.out.println("Map …我想要一个正则表达式的全名与称呼.谁能帮帮我吗.
^[A-Za-z] ([A-Za-z] (\\s|\\.|_)?)+[a-zA-Z]*$
这是我的正则表达式,我用它作为全名,但它并没有表示敬意.
我在进行密码验证方面遇到了麻烦.我从名为applicationconstants的java类中获取密码范围的最小值和最大值,并在servlet中调用它.我在另一个java类中使用验证函数并在servlet中调用它.请帮我解决这个问题.
servlet代码
int minLength = ApplicationConstants.PASSWORD_MIN_LENGTH;
int maxLength = ApplicationConstants.PASSWORD_MAX_LENGTH;
if (user.getUserPassword().length() > 0 || user.getUserPassword() !=null) {
if (Validation.validateStringLengthRange(user.getUserPassword(), minLength, maxLength)) {
System.out.println("servlet");
isvalidate = false;
hashMap.put("password", props.getText("error.password.compare.outofrange"));
session.setAttribute("errorMessage", hashMap);
}
}
Validation.java
public static boolean validateStringLengthRange(String name, int min, int max) {
boolean isValid = true;
int len = name.length();
if (len > 0) {
if (len < min || len > max) {
System.out.println("validation.java");
isValid = false;
}
}
return isValid;
}
