Propriété Meta httpEquiv

❮ Méta-objet

Exemple

Renvoyez l'en-tête HTTP pour les informations dans l'attribut content :

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

Définition et utilisation

La propriété httpEquiv définit ou renvoie un en-tête HTTP pour les informations de l'attribut content.

L'attribut http-equiv peut être utilisé pour simuler un en-tête de réponse HTTP.

La valeur de l'attribut http-equiv dépend de la valeur de l'attribut content.

Remarque : Si l'attribut name est défini, l'attribut http-equiv ne doit pas l'être.

Property
httpEquiv Yes Yes Yes Yes Yes


Syntaxe

Renvoyez la propriété httpEquiv :

metaObject.httpEquiv

Définissez la propriété httpEquiv :

metaObject.httpEquiv = HTTP-header

Certaines valeurs d'en-tête HTTP couramment utilisées sont :

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.

Valeur de retour

Type Description
String Information about the HTTP response message header
