NAME¶

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.

new¶

allow_filter¶
