PROPERTIES

Inherits properties from its parent HTML::Object::DOM::Element

METHODS

Inherits methods from its parent HTML::Object::DOM::Element

EVENTS

Event listeners for those events can also be found by prepending on before the event type:

click event listeners can be set also with onclick method:

$e->onclick(sub{ # do something });
# or as an lvalue method
$e->onclick = sub{ # do something };

input

Fires when the value of an input, select, or textarea element has been changed.

Example:

<input placeholder="Enter some text" name="name"/>
<p id="values"></p>

my $input = $doc->querySelector('$input');
my $log = $doc->getElementById('values');

$input->addEventListener( input => \&updateValue );

sub updateValue
{
    my $e = shift( @_ );
    $log->textContent = $e->target->value;
}

selectionchange

Under perl, this does not do anything of course, but you can fire yourself the event.

Under JavaScript, this fires when the text selection in a textarea element has been changed.

Example:

<div>Enter and select text here:<br><textarea id="mytext" rows="2" cols="20"></textarea></div>
<div>selectionStart: <span id="start"></span></div>
<div>selectionEnd: <span id="end"></span></div>
<div>selectionDirection: <span id="direction"></span></div>

my $myinput = $doc->getElementById( 'mytext' );

$myinput->addEventListener( selectionchange => sub
{
    $doc->getElementById( 'start' )->textContent = $mytext->selectionStart;
    $doc->getElementById( 'end' )->textContent = $mytext->selectionEnd;
    $doc->getElementById( 'direction' )->textContent = $mytext->selectionDirection;
});
