Name
    HTML::Accessors - Generate HTML elements

Version
    0.1.$Rev: 18 $

Synopsis
       use HTML::Accessors;

       my $htag = HTML::Accessors->new();

       # Create an anchor element
       $anchor = $htag->a( { href => 'http://...' }, 'This is a link' );

Description
    Uses HTML::GenerateUtil to create an autoload method for each of the
    elements defined by HTML::Tagset. The API was loosely taken from CGI.
    Using the CGI module is undesirable in a Catalyst application (run from
    the development server) due go greediness issues over STDIN.

    The returned tags are XHTML 1.1 compliant.

Subroutines/Methods
  new
    The constructor is inherited from Class::Accessor::Fast and takes no
    options

  escape_html
    Expose "HTML::GenerateUtil::escape_html"

  popup_menu
    Returns the "<select>" element. The first option passed to "popup_menu"
    is either a hash ref or a list of key/value pairs. The keys are:

    default
       Determines which of the values will be selected by default

    labels
       Display these labels in place of the values (but return the value of
       the selected label). This is a hash ref with a key for each element
       in the "values" array

    values
       The key references an array ref whose values are used as the list of
       options returned in the body of the "<select>" element

    The rest of the keys and values are passed as attributes to the
    "<select>" element. For example:

       $ref = { default => 1, name => q(my_field), values => [ 1, 2 ] };
       $htag->popup_menu( $ref );

    would return:

       <select name="my_field">
          <option selected="selected">1E</option>
          <option>2E</option>
       </select>

  radio_group
    Generates a list of radio input buttons with labels. Break elements can
    be inserted to create rows of a given number of columns when displayed.
    The first option passed to "radio_group" is either a hash ref or a list
    of key/value pairs. The keys are:

    columns
       Integer number of columns to display the generated buttons in. If
       zero then a list of radio buttons without breaks is generated

    default
       Determines which of the radio box will be selected by default

    labels
       Display these labels next to each button. This is a hash ref with a
       key for each element in the "values" array

    name
       The form name of the generated buttons

    onchange
       An optional Javascript reference. The JS will be executed each time a
       different radio button is selected

    values
       The key references an array ref whose values are returned by the
       radio buttons

    For example:

       $ref = { columns => 2,
                default => 1,
                labels  => { 1 => q(Button One),
                             2 => q(Button Two),
                             3 => q(Button Three),
                             4 => q(Button Four), },
                name    => q(my_field),
                values  => [ 1, 2, 3, 4 ] };
       $htag->radio_group( $ref );

    would return:

       <label>
          <input checked="checked" tabindex="1" value="1" name="my_field" type="radio" />Button One
       </label>
       <label>
          <input tabindex="2" value="2" name="my_field" type="radio" />Button Two
       </label>
       <br />
       <label>
          <input tabindex="3" value="3" name="my_field" type="radio" />Button Three
       </label>
       <label>
          <input tabindex="4" value="4" name="my_field" type="radio" />Button Four
       </label>
       <br />

  scrolling_list
    Calls "popup_menu" with the "multiple" argument set to "multiple". This
    has the effect of allowing multiple selections to be returned from the
    popup menu

  AUTOLOAD
    Uses HTML::Tagset to check if the requested method is a known HTML
    element. If it is "AUTOLOAD" uses HTML::GenerateUtil to create the tag

    If the first option is a hash ref then the keys and values are copied
    and passed to "HTML::GenerateUtil::generate_tag" which uses them to set
    the attributes on the created element. The next option is treated as the
    element's body text and overrides the "default" attribute which is
    passed and deleted from the options hash

    If the requested element exists in the hard coded list of input
    elements, then the element is set to "input" and the mapped value used
    as the type attribute in the call to "generate_tag". For example;

       $htag->textfield( { default => q(default value), name => q(my_field) } );

    would return

       <input value="default value" name="my_field" type="text" />

    The list of input elements contains; button, checkbox, hidden,
    image_button, password_field, radio_button, submit, and textfield

  DESTROY
    Implement the "DESTROY" method so that the "AUTOLOAD" method doesn't get
    called instead. Re-dispatches the call upstream

  _carp
    Call "Carp::carp". Don't load Carp if we don't have to

  _croak
    Call "Carp::croak". Don't load Carp if we don't have to

Configuration and Environment
    None

Diagnostics
    "Carp::carp" is called to issue a warning about undefined elements
