HTMLBaseElement: href 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 href property of the HTMLBaseElement interface contains a string that is the URL to use as the base for relative URLs.

It reflects the href attribute of the <base> element.

Value

A string that contains a URL, or the empty string ("") if the corresponding <base> element does not include the href attribute.

This example demonstrates that the href attribute in <base> is reflected in the href property of HTMLBaseElement.

const logElement = document.querySelector("#log");
function log(text) {
  logElement.innerText = text;
}

#log {
  height: 20px;
}

html

js
const base = document.getElementsByTagName("base")[0];
log(`base.href="${base.href}"`);
