NAME

HTML::Object::DOM::ValidityState - HTML Object DOM Valid State Class

SYNOPSIS

use HTML::Object::DOM::ValidityState;
my $validity = HTML::Object::DOM::ValidityState->new || 
    die( HTML::Object::DOM::ValidityState->error, "\n" );

VERSION

v0.2.0

DESCRIPTION

The ValidityState interface represents the validity states that an element can be in, with respect to constraint validation. Together, they help explain why an element's value fails to validate, if it is not valid.

This is used only so that some properties work (like "validity" in HTML::Object::DOM::Element::Button), but since this is for interactive interface, which perl does not provide, it has limited use. Anyhow, you can set those boolean values yourself.

PROPERTIES

For each of these boolean properties, a value of true indicates that the specified reason validation may have failed is true, with the exception of the valid property, which is true if the element's value obeys all constraints.

badInput

A boolean value that is true if the user has provided input that the browser is unable to convert.

Example:

<input type="number" id="age">

my $input = $doc->getElementById( 'age' );
if( $input->validity->badInput )
{
    say( "Bad $input detected…" );
}
else
{
    say( "Content of $input OK." );
}

customError

A boolean value indicating whether the element's custom validity message has been set to a non-empty string by calling the element's setCustomValidity() method. This setCustomValidity method is implemented in HTML::Object::DOM::Element::Input, HTML::Object::DOM::Element::Object and HTML::Object::DOM::Element::Select

See also Mozilla documentation

patternMismatch

A boolean value that is true if the value does not match the specified pattern, and false if it does match. If true, the element matches the :invalid CSS pseudo-class.

Example:

<p>
<label>Enter your phone number in the format (123)456-7890
    (<input name="tel1" type="tel" pattern="[0-9]{3}" placeholder="###" aria-label="3-digit area code" size="2"/>)-
     <input name="tel2" type="tel" pattern="[0-9]{3}" placeholder="###" aria-label="3-digit prefix" size="2"/> -
     <input name="tel3" type="tel" pattern="[0-9]{4}" placeholder="####" aria-label="4-digit number" size="3"/>
</label>
</p>

input:invalid {
    border: red solid 3px;
}

rangeOverflow

A boolean value that is true if the value is greater than the maximum specified by the max attribute, or false if it is less than or equal to the maximum. If true, the element matches the :invalid and :out-of-range and CSS pseudo-classes.

Example:

<input type="number" min="20" max="40" step="2" />

See also Mozilla documentation

rangeUnderflow

A boolean value that is true if the value is less than the minimum specified by the min attribute, or false if it is greater than or equal to the minimum. If true, the element matches the :invalid and :out-of-range CSS pseudo-classes.

Example:

<input type="number" min="20" max="40" step="2" />

See also Mozilla documentation

stepMismatch

A boolean value that is true if the value does not fit the rules determined by the step attribute (that is, it is not evenly divisible by the step value), or false if it does fit the step rule. If true, the element matches the :invalid and :out-of-range CSS pseudo-classes.

Example:

<input type="number" min="20" max="40" step="2" />

See also Mozilla documentation

tooLong

A boolean value that is true if the value exceeds the specified maxlength for HTML::Object::DOM::Element::Input or HTML::Object::DOM::Element::TextArea objects, or false if its length is less than or equal to the maximum length. Note: This property is never true in Gecko, because elements' values are prevented from being longer than maxlength. If true, the element matches the :invalid and :out-of-range CSS pseudo-classes.

See also Mozilla documentation

tooShort

A boolean value that is true if the value fails to meet the specified minlength for HTML::Object::DOM::Element::Input or HTML::Object::DOM::Element::TextArea objects, or false if its length is greater than or equal to the minimum length. If true, the element matches the :invalid and :out-of-range CSS pseudo-classes.

See also Mozilla documentation

typeMismatch

A boolean value that is true if the value is not in the required syntax (when type is email or url), or false if the syntax is correct. If true, the element matches the :invalid CSS pseudo-class.

Example:

<p>
 <label>
    Enter an email address:
    <input type="email" value="example.com" />
 </label>
</p>
<p>
 <label>
    Enter a URL:
    <input type="url" value="example.com" />
    </label>
</p>

input:invalid {
    border: red solid 3px;
}

See also Mozilla documentation

valid

A boolean value that is true if the element meets all its validation constraints, and is therefore considered to be valid, or false if it fails any constraint. If true, the element matches the :valid CSS pseudo-class; the :invalid CSS pseudo-class otherwise.

See also Mozilla documentation

valueMissing

A boolean value that is true if the element has a required attribute, but no value, or false otherwise. If true, the element matches the :invalid CSS pseudo-class.
