A validator that checks user input against a regular expression.
This validator checks whether user input matches the given regular expression. It checks the complete input; prefix ^ and suffix $ are not needed.
The regex should be specified using ECMAScript syntax (http://en.cppreference.com/w/cpp/regex/ecmascript)
Usage example:
The strings used in this class can be translated by overriding the default values for the following localization keys:
| Wt::WRegExpValidator::WRegExpValidator | ( | const WString & | pattern | ) |
Sets a new regular expression validator that accepts input that matches the given regular expression.
This constructs a validator that matches the regular expression expr.
| WString Wt::WRegExpValidator::invalidNoMatchText | ( | ) | const |
Returns the message displayed when the input does not match.
|

Creates a Javascript object that validates the input.
The JavaScript expression should evaluate to an object which contains a validate(text) function, which returns an object that contains the following two fields:
message that indicates the problem if not valid.Returns an empty string if the validator does not provide a client-side validation implementationq.

| WString Wt::WRegExpValidator::regExpPattern | ( | ) | const |
Returns the regular expression for valid input.
Returns the ECMAScript regular expression.
| void Wt::WRegExpValidator::setInvalidNoMatchText | ( | const WString & | text | ) |
Sets the message to display when the input does not match.
The default value is "Invalid input".
| void Wt::WRegExpValidator::setRegExp | ( | const WString & | pattern | ) |
Sets the regular expression for valid input.
Sets the ECMAscript regular expression expr.
Validates the given input.
The input is considered valid only when it is blank for a non-mandatory field, or matches the regular expression.
