Hi, I have the following Java code to validate a password box.
Basically it checks that the password can't be null, is between 8-15
characters, and must contain both numbers and letters.
public static boolean validatePassword(PasswordTextBox box, Label
errorLabel) {
String text = box.getText();
if(text.isEmpty()) {
ValidatorUtil.onFailure(box,
custom.passwordMayNotBeNull(),
errorLabel);
return false;
} if(text.length() < 8 || text.length() > 15) {
ValidatorUtil.onFailure(box,
custom.passwordHasInvalidLength(8, 15,
text.length()), errorLabel);
return false;
} if(!text.matches(CustomMessages.REGEX_PASSWORD)) {
ValidatorUtil.onFailure(box,
custom.passwordHasInvalidFormat(),
errorLabel);
return false;
}
return true;
}
This works fine in Firefox, but it does not work in IE. The
JavaScript compiles down to this for IE8:
function validatePassword(box, errorLabel){
var text, matchObj;
text = $getPropertyString(box.element, 'value');
if (!text.length) {
setStyleName(box.element, 'validationFailedBorder', true);
($clinit_114() , errorLabel.element).innerText = 'You must provide
a password.';
return false;
}
if (text.length < 8 || text.length > 15) {
onFailure_1(box, 'Sorry, your password must be between 8 and 15
characters long (you have ' + text.length + ' characters).',
errorLabel);
return false;
}
if (!(matchObj = (new RegExp('^(?=.*\\d)(?=.*[a-z]).{8,15}$')).exec
(text) , matchObj == null?false:text == matchObj[0])) {
setStyleName(box.element, 'validationFailedBorder', true);
($clinit_114() , errorLabel.element).innerText = 'Sorry, your
password must contain both letters [a-z] and numbers [0-9].';
return false;
}
return true;
}
The behavior is a bit odd. It passes the text.length checks, but then
fails the regex expression (which also has length checks with {8,15}.
It always prints: 'Sorry, your password must contain both letters [a-
z] and numbers [0-9].' in IE, but in Firefox, it works fine...for
inputs like this:
abcd1234 <- valid password, 8 characters with letters and numbers
Even more strange is the fact that if I enter a password with 12
characters with both letters and numbers, IE passes, like this:
abcd1234abcd
But if I enter only 11 characters, it fails:
abcd1234abc
Any clues on what is wrong here?
