Member Function Documentation

std::string Wt::WTimeValidator::javaScriptValidate ( ) const
overridevirtual

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:

  • a message that indicates the problem if not valid.

Returns an empty string if the validator does not provide a client-side validation implementationq.

void Wt::WTimeValidator::setBottom ( const WTime bottom)

Sets the lower limit of the valid time range.

The default is a null time constructed using WTime()

void Wt::WTimeValidator::setFormat ( const WString format)

Sets the validator format.

WTime::toString()
void Wt::WTimeValidator::setTop ( const WTime top)

Sets the upper limit of the valid time range.

The default is a null time constructed using WTime()

WValidator::Result Wt::WTimeValidator::validate ( const WString input) const
overridevirtual

Validates the given input.
