How I can validate date of birth?

Month-Date-Year

Example: 11-21-1960

Thanks

You could use a date object that allows you to set a display and edit pattern that would match the date format you want.

You could use a regular expression:

E.g.

var dateRegExp = "^(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01])-(19|20)\d\d$"; // mm-dd-yyyy

if (oField.rawValue.search(dateRegExp) === -1) {

     // error!

}

Or you could use a date object as suggested in the previous post, but also stop the user from typing in a date so they will be forced to use the date selection box. This would ensure that the date is always in the correct format. To stop the user from typing in data, put the following code in the change event for the field:

if (xfa.event.change.length == 1) {

xfa.event.change = "";

}

On Validate event:

var dateRegExp = "^(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01])-(19|20)\d\d$"; // mm-dd-yyyy

if (oField.rawValue.search(dateRegExp) === -1) {

     // error!

}

I am getting a error if I type: 11-12-2011

What can be wrong?

Thanks

Sorry, the backslashes must be escaped, i.e. add an additional backslash to the start of "\d" (or replace "\d" with "[0-9]"). E.g:

var dateRegExp = "^(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01])-(19|20)\\d\\d$"; // mm-dd-yyyy

if (this.rawValue.search(dateRegExp) === -1) {
     false;
}
else {
     true;
}
