Reading the
HTMLMetaElement: httpEquiv property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The HTMLMetaElement.httpEquiv
property gets or sets the pragma directive or an HTTP response header name for the HTMLMetaElement.content
attribute.
For more details on the possible values, see the http-equiv attribute.
Value
A string.
Examples
>Reading the http-equiv
value of a meta element
The following example queries a <meta>
element with an http-equiv
attribute.
The http-equiv
attribute is logged to the console showing a refresh
pragma directive that instructs the browser to refresh the page after a number of seconds defined by the content
attribute:
js
// given <meta http-equiv="refresh" content="10" />
const meta = document.querySelector("meta[http-equiv]");
console.log(meta.httpEquiv);
// refresh
console.log(meta.content);
// 10
