HTML::Widget::JavaScript - Adds JavaScript validation to HTML::Widget


Version 0.01


This module adds JavaScript field validation for HTML::Widget objects.

When a JavaScript checked constraint fails, an alert box with the given error message (set by the message() constraint method) is displayed.

Currently, these constraints are implemented in JavaScript: All, AllOrNone, Any, ASCII, Email (simplified), Equal, HTTP, In, Integer, Length, Printable, Range and String.

In other words, these constraints are missing: Date, DateTime, Time and Regex. Note that, although JavaScript support is missing, they will continue to work using server-side validation.


See HTML::Widget.

$self->result( $query, $uploads )

$self->process( $query, $uploads )

After finishing setting up the widget and all its elements, call either process() or result() to create an HTML::Widget::JavaScript::Result. If passed a $query it will run filters and validation on the parameters. The Result object can then be used to produce the HTML.


Implement the missing constraints.

Maybe add support for altering the error displaying behaviour (e.g. instead of using alert(), maybe we could fill the error span with the error messages directly through JavaScript).
