메타 httpEquiv 속성

❮ 메타 객체

예시

content 속성의 정보에 대한 HTTP 헤더를 반환합니다.

var x = document.getElementsByTagName("META")[0].httpEquiv;

정의 및 사용

httpEquiv 속성은 콘텐츠 속성의 정보에 대한 HTTP 헤더를 설정하거나 반환합니다.

http-equiv 속성은 HTTP 응답 헤더를 시뮬레이션하는 데 사용할 수 있습니다.

http-equiv 속성의 값은 content 속성의 값에 따라 다릅니다.

참고: name 속성이 설정된 경우 http-equiv 속성이 설정되지 않아야 합니다.


브라우저 지원

Property
httpEquiv Yes Yes Yes Yes Yes


통사론

httpEquiv 속성을 반환합니다.

metaObject.httpEquiv

httpEquiv 속성을 설정합니다.

metaObject.httpEquiv = HTTP-header

일반적으로 사용되는 일부 HTTP 헤더 값은 다음과 같습니다.

Value Description
content-type Specifies the character set for the contents of the document.

Tip: It is recommended to always specify the character set.

Example:

<meta http-equiv="content-type" content="text/html; charset=UTF-8">

default-style Specifies the preferred style sheet to use.

Example:

<meta http-equiv="default-style" content="the documents preferred stylesheet">

Note: The value of the content attribute above must match the value of the ttitle attribute on a link element in the same document, or it must match the value of the title attribute on a style element in the same document.

refresh Defines a time interval for the document to refresh itself.

Example:

<meta http-equiv="refresh" content="300">

Note: The value "refresh" should be used carefully, as it takes the control of a page away from the user. Using "refresh" will cause a failure in W3C's Web Content Accessibility Guidelines.

반환 값

Type Description
String Information about the HTTP response message header

예시

http-equiv 및 콘텐츠 속성의 값을 변경합니다. 다음 예에서는 30초마다 문서를 새로 고칩니다.

document.getElementsByTagName("META")[0].httpEquiv = "refresh";
document.getElementsByTagName("META")[0].content = "30";
