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
