HTMLAnchorElement: attributionSourceId property

The attributionSourceId property of the HTMLAnchorElement interface gets and sets the attributionsourceid HTML attribute on an <a> element.

The attributionSourceId is used as part of the Private Click Measurement specification to identify the content that was clicked when following a link to another site.

Value

A number. Valid values for private click measurement are between 0 and 255. The default value is 0. Values outside this range will not cause an error when setting the property, but will be ignored by the browser for attribution purposes.

Examples

const adLink = document.getElementById("ad-link");
