속성

이 요소는 전역 속성을 포함합니다.

autocapitalize

This is a nonstandard attribute used by iOS Safari Mobile which controls whether and how the text value should be automatically capitalized as it is entered/edited by the user. The non-deprecated values are available in iOS 5 and later. Possible values are:

• none: Completely disables automatic capitalization
• sentences: Automatically capitalize the first letter of sentences.
• words: Automatically capitalize the first letter of words.
• characters: Automatically capitalize all characters.
• on: Deprecated since iOS 5.
• off: Deprecated since iOS 5.

autocomplete HTML5

This attribute indicates whether the value of the control can be automatically completed by the browser. Possible values are:

• off: The user must explicitly enter a value into this field for every use, or the document provides its own auto-completion method; the browser does not automatically complete the entry.
• on: The browser can automatically complete the value based on values that the user has entered during previous uses.

If the autocomplete attribute is not specified on an textarea element, then the browser uses the autocomplete attribute value of the <textarea> element's form owner. The form owner is either the form element that this <textarea> element is a descendant of or the form element whose id is specified by the form attribute of the input element. For more information, see the autocomplete attribute in <form>.

autofocus HTML5

이 불리언 속성은 페이지가 로드 됬을때, 포커스를 오버라이드(예:사용자가 다른 컨트롤에 타이핑) 하지 않는다면, 폼 컨트롤이 입력 포커스를 받을지를 지정합니다.문서에서 오직 하나의 폼 관련 요소만이 이 속성이 지정될수 있습니다.

cols

The visible width of the text control, in average character widths. If it is specified, it must be a positive integer. If it is not specified, the default value is 20 (HTML5).

disabled

사용자가 컨트롤과 상호작용할수 없다는것을 가리키는 불리언 속성 (만약 속성이 지정되지 않았다면, 이 요소를 포함하는 컨테이닝 요소(예: <fieldset>)에게서 값을 상속받습니다. 예를 들면, disabled 속성을 가진 컨테이닝 요소가 없다면, 컨트롤은 사용 가능합니다)

form HTML5

The form element that the textarea element is associated with (its "form owner"). The value of the attribute must be an ID of a form element in the same document. If this attribute is not specified, the textarea element must be a descendant of a form element. This attribute enables you to place textarea elements anywhere within a document, not just as descendants of their form elements.

maxlength HTML5

The maximum number of characters (Unicode code points) that the user can enter. If it is not specified, the user can enter an unlimited number of characters.

minlength HTML5

The minimum number of characters (Unicode code points) required that the user should enter.

name

컨트롤의 이름

placeholder HTML5

A hint to the user of what can be entered in the control. The placeholder text must not contain carriage returns or line-feeds.

readonly

이 불리언 속성은 사용자가 컨트롤의 값을 수정할수 없다는것을 가리킵니다. disabled 속성과는 다르게, readonly 속성은 사용자가 컨트롤을 클릭하거나 선택하는것을 막지 않습니다. readonly 컨트롤의 값은 여전히 폼과 함께 제출 됩니다..

required HTML5

이 속성은 사용자가 폼을 제출하기 전에 반드시 채워야 한다는 것을 가리킵니다.

rows

The number of visible text lines for the control.

selectionDirection HTML5

The direction in which selection occurred. This is "forward" if the selection was made from left-to-right in an LTR locale or right-to-left in an RTL locale, or "backward" if the selection was made in the opposite direction. This can be "none" if the selection direction is unknown.

selectionEnd

The index to the last character in the current selection.

selectionStart

The index to the first character in the current selection.

spellcheck HTML5

Setting the value of this attribute to true indicates that the element needs to have its spelling and grammar checked. The value default indicates that the element is to act according to a default behavior, possibly based on the parent element's own spellcheck value. The value false indicates that the element should not be checked.

wrap HTML5

Indicates how the control wraps text. Possible values are:

• hard: The browser automatically inserts line breaks (CR+LF) so that each line has no more than the width of the control; the cols attribute must be specified.
• soft: The browser ensures that all line breaks in the value consist of a CR+LF pair, but does not insert any additional line breaks.

If this attribute is not specified, soft is its default value.

DOM 인터페이스

이 요소는 HTMLTextAreaElement 인터페이스를 구현합니다.

Gecko 2.0 introduced support for resizable textareas. This is controlled by the resize CSS property. Resizing of textareas is enabled by default, but you can explicitly disable it by including the following CSS:

textarea {
  resize: none;
}

CSS와 상호작용 하기

In regards to CSS, an <textarea> is a replaced element. The HTML specification doesn't define where the baseline of a <textarea> is. So different browsers set it to different positions. For Gecko, the <textarea> baseline is set on the baseline of the first line of the textarea's first line, on another browser it may be set on the bottom of the <textarea> box. Don't use vertical-align: baseline on it, as the behavior will be unpredictable.

Textarea 는 래스터 이미지 처럼 고유한 넓이를 가지고 있습니다.

예제

HTML Content

<textarea name="textarea" rows="10" cols="50">Write something here</textarea>

사양

브라우저 호환성

Safari Mobile for iOS applies a default style of opacity: 0.4 to disabled <textarea> elements. Other major browsers don't currently share this particular default style.

Gecko 참고

Starting in Gecko 6.0 (Firefox 6.0 / Thunderbird 6.0 / SeaMonkey 2.3), when a <textarea> is focused, the insertion point is placed at the beginning of the text by default, instead of at the end. This change makes Gecko's behavior consistent with other popular browsers.

Firefox for Android, by default, sets a background-image gradient on all <textarea> elements. This can be disabled using background-image: none.
