class js.html.TextAreaElement extends Element

Available on js

DOM TextArea objects expose the HTMLTextAreaElement (or HTML 4 HTMLTextAreaElement) interface, which provides special properties and methods (beyond the regular element object interface they also have available to them by inheritance) for manipulating the layout and presentation of <textarea> elements.

Documentation for this class was provided by MDN.

Instance Fields

var autofocus:Bool

Reflects the

autofocus HTML attribute, indicating that the control should have input focus when the page loads

var cols:Int

Reflects the

cols HTML attribute, indicating the visible width of the text area.

var defaultValue:String

The control's default value, which behaves like the textContent property.

var dirName:String

var disabled:Bool

Reflects the

disabled HTML attribute, indicating that the control is not available for interaction.

var form:FormElement

The containing form element, if this element is in a form. If this element is not contained in a form element:

  • HTML5 this can be the id attribute of any <form> element in the same document.
  • HTML 4 this must be null.

var labels:NodeList

A list of <label> elements that are labels for this element.

var maxLength:Int

Reflects the

maxlength HTML attribute, indicating the maximum number of characters the user can enter. This constraint is evaluated only when the value changes. Setter throws DOMException.

var name:String

Reflects

name HTML attribute, containing the name of the control.

var placeholder:String

Reflects the

placeholder HTML attribute, containing a hint to the user about what to enter in the control.

var readOnly:Bool

Reflects the

readonly HTML attribute, indicating that the user cannot modify the value of the control.

var required:Bool

Reflects the

required HTML attribute, indicating that the user must specify a value before submitting the form.

var rows:Int

Reflects the

rows HTML attribute, indicating the number of visible text lines for the control.

var selectionDirection:String

The direction in which selection occurred. This is "forward" if selection was performed in the start-to-end direction of the current locale, or "backward" for the opposite direction. This can also be "none" if the direction is unknown."

var selectionEnd:Int

The index of the end of selected text. HTML5 If no text is selected, contains the index of the character that follows the input cursor. On being set, the control behaves as if setSelectionRange() had been called with this as the second argument, and selectionStart as the first argument.

var selectionStart:Int

The index of the beginning of selected text. HTML5 If no text is selected, contains the index of the character that follows the input cursor. On being set, the control behaves as if setSelectionRange() had been called with this as the first argument, and selectionEnd as the second argument.

var textLength:Int

The codepoint length of the control's value.

var type:String

The string textarea.

var validationMessage:String

A localized message that describes the validation constraints that the control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (willValidate is false), or it satisfies its constraints.

var validity:ValidityState

The validity states that this element is in.

var value:String

The raw value contained in the control.

var willValidate:Bool

Indicates whether the element is a candidate for constraint validation. It is false if any conditions bar it from constraint validation.

var wrap:String
