HTML::Widget::Element - Element Base Class
SYNOPSIS
my $e = $widget->element( $type, $name, {disabled => 'disabled'} );
$e->name('bar');
$e->class('foo');
DESCRIPTION
Element Base Class.
METHODS
new
attributes
attrs
Arguments: %attributes
Arguments: \%attributes
Return Value: $element
Arguments: none
Return Value: \%attributes
Accepts either a list of key/value pairs, or a hash-ref.
$e->attributes( $key => $value );
$e->attributes( { $key => $value } );
Returns the $element object, to allow method chaining.
As of v1.10, passing a hash-ref no longer deletes current attributes, instead the attributes are added to the current attributes hash.
This means the attributes hash-ref can no longer be emptied using "$e->attributes( { } );". Instead, you may use "%{ $e->attributes } =
();".
As a special case, if no arguments are passed, the return value is a hash-ref of attributes instead of the object reference. This provides
backwards compatibility to support:
$e->attributes->{key} = $value;
"attrs" is an alias for "attributes".
container
Arguments: \%attributes
Return Value: $container
Creates a new $container_class. Defaults to HTML::Widget::Container.
id
Arguments: $widget
Return Value: $id
Creates a element id.
init
Arguments: $widget
Called once when process() gets called for the first time.
mk_error
Arguments: $widget, @errors
Return Value: $error
Creates a new HTML::Widget::Error.
mk_input
Arguments: $widget, \%attributes, @errors
Return Value: $input_tag
Creates a new input tag.
mk_tag
Arguments: $widget, $tagtype, \%attributes, @errors
Return Value: $element_tag
Creates a new tag.
mk_label
Arguments: $widget, $name, $comment, @errors
Return Value: $label_tag
Creates a new label tag.
name
Arguments: $name
Return Value: $name
Contains the element name.
passive
Arguments: $bool
Return Value: $bool
Defines if element gets automatically rendered.
prepare
Arguments: $widget
Called whenever "$widget->process" gets called, before "$element->process".
process
Arguments: \%params, @uploads
Return Value: @errors
Called whenever "$widget->process" is called.
Returns an arrayref of HTML::Widget::Error objects.
containerize
Arguments: $widget, $value, @errors
Return Value: $container_tag
Containerize the element, label and error for later rendering. Uses HTML::Widget::Container by default, but this can be over-ridden on a
class or instance basis via "container_class".
container_class
Arguments: $class
Return Value: $class
Contains the class to use for contain the element which then get rendered. Defaults to HTML::Widget::Container. "container_class" can be
set at a class or instance level:
HTML::Widget::Element->container_class('My::Container');
# Override default to custom class
HTML::Widget::Element::Password->container_class(undef);
# Passwords use the default class
$w->element('Textfield')->name('foo')->container_class->('My::Other::Container');
# This element only will use My::Other::Container to render
find_elements
Return Value: @elements
For non-block-container elements, simply returns a one-element list containing this element.
