WRegExpValidator (const WString &expr, WObject *parent=0) | |
Create a new regular expression validator that accepts input that matches the given regular expression. | |
~WRegExpValidator () | |
Delete the regexp validator. | |
void | setRegExp (const WString &expr) |
Set the regular expression for valid input. | |

std::string | javaScriptValidate (const std::string &jsRef) const |
Creates a Javascript expression that validates the input. |
This validator checks whether user input is matched by the given (perl-like) regular expression.
The following perl features are not supported (since client-side validation cannot handle them):
This validator does not fully support unicode: it matches on the UTF8-encoded representation of the string.
Wt::WRegExpValidator::WRegExpValidator | ( | const boost::regex & | rx | ) |
Create a new regular expression validator that accepts input that matches the given regular expression (in UTF8 encoding).
Create a new regular expression validator that accepts input that matches the given regular expression.
This constructs a validator that matches the perl regular expression expr.
void Wt::WRegExpValidator::setRegExp | ( | const WString & | expr | ) |
Set the regular expression for valid input.
Sets the perl regular expression expr.
WValidator::State Wt::WRegExpValidator::validate | ( | WString & | input, | |
int & | pos | |||
) | const [virtual] |
Validate the given input.
The input is considered valid only when it is blank for a non-mandatory field, or matches the regular expression.
Reimplemented from Wt::WValidator.
void Wt::WRegExpValidator::setInvalidNoMatchText | ( | const WString & | text | ) |
Set the message to display when the input does not match.
The default value is "Invalid input".
WString Wt::WRegExpValidator::invalidNoMatchText | ( | ) | const |
Returns the message displayed when the input does not match.
std::string Wt::WRegExpValidator::javaScriptValidate | ( | const std::string & | jsRef | ) | const [protected, virtual] |
Creates a Javascript expression that validates the input.
The JavaScript expression should evaluate to an object with two fields: a boolean valid, and a message that indicates the problem if not valid.
Return an empty string if you are not provide the client-side validation.
