Meta httpEquiv- Eigenschaft

❮ Meta-Objekt

Beispiel

Geben Sie den HTTP-Header für die Informationen im Inhaltsattribut zurück:

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

Definition und Verwendung

Die Eigenschaft httpEquiv legt einen HTTP-Header für die Informationen im Inhaltsattribut fest oder gibt ihn zurück.

Das Attribut http-equiv kann verwendet werden, um einen HTTP-Antwortheader zu simulieren.

Der Wert des http-equiv-Attributs hängt vom Wert des content-Attributs ab.

Hinweis: Wenn das name-Attribut gesetzt ist, sollte das http-equiv-Attribut nicht gesetzt werden.


Browser-Unterstützung

Property
httpEquiv Yes Yes Yes Yes Yes


Syntax

Geben Sie die httpEquiv-Eigenschaft zurück:

metaObject.httpEquiv

Legen Sie die httpEquiv-Eigenschaft fest:

metaObject.httpEquiv = HTTP-header

Einige häufig verwendete HTTP-Header- Werte sind:

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.

Rückgabewert

Type Description
String Information about the HTTP response message header
