HTML::DOM::Element::Input - A Perl class for representing 'input' elements in an
HTML DOM tree
use HTML::DOM;
$doc = HTML::DOM->new;
$elem = $doc->createElement('input');
$elem->setAttribute('type' => 'text');
$elem->click();
$elem->blur();
# etc.
$elem->checked(1) # set attribute
$elem->type; # get attribute
$elem->tagName;
# etc.
This class implements 'input' elements in an HTML::DOM tree. It implements the
HTMLInputElement DOM interface and inherits from HTML::DOM::Element (q.v.).
In addition to those inherited from HTML::DOM::Element and its superclasses,
this class implements the following DOM methods:
- defaultValue
- defaultChecked
- accept
- accessKey
- align
- alt
- disabled
- maxLength
- name
- readOnly
- size
- src
- tabIndex
- type
- useMap
- Each of these returns the corresponding HTML attribute (the 'value' and
'checked' attributes in the case of
"defaultValue" and
"defaultChecked", respectively). If you
pass an argument, it will become the new value of the attribute, and the
old value will be returned.
- form
- Returns the form containing this input element.
- checked
- value
- These methods allow one to change the state of the input field. The change
is not reflected in the HTML attributes. These will be called with the
values of "defaultValue" and
"defaultChecked" when the form's
"reset" method is invoked.
The "value" method behaves
differently if the calling package is HTML::Form, HTML::Form::Input or
WWW::Mechanize. For checkboxes, the return value will be undef if the
box is not checked. With an undef argument the box will be unchecked. If
an argument is given that is the same as the 'value' attribute, the box
will be checked. If any other argument is passed, it will die. If the
'type' attribute is 'button' or 'reset,'
"value" will simply return.
- blur
- focus
- select
- click
- Each of these triggers the corresponding event. The
"click" method can take three arguments,
all optional: (0) the form, (1) the x-coordinate where the mouse
supposedly clicked and (2) the y-coordinate.
In addition, the following methods are provided for compatibility
with WWW::Mechanize:
- possible_values
- This returns an empty list for most input elements, but for checkboxes it
returns "(undef, $value)".
- form_name_value
- Returns a list of two items: (0) the name of the field and (1) the
value.
- file
- An alias for "value"
- filename
- This get/sets the filename reported to the server during file upload. This
attribute defaults to the value reported by the file() method.
- headers
- Returns an empty list (for now).
- content
- This get/sets the file content provided to the server during file upload.
This method can be used if you do not want the content to be read from an
actual file.
