govuk_publishing_components: Google Analytics 4 copy tracker
This script creates an event when text is copied from a GOV.UK page. When initialised, it adds an event listener to the page for the copy event. An event will be fired if the following are true:
- some text has been selected
- the selected text is not inside an INPUT or TEXTAREA
The second check is based around concerns over PII. Text copied from the body of a GOV.UK page should not include PII, but text inside a text input is written by users, and therefore could contain PII. Note that if text is selected spanning multiple elements including a text input, the browser automatically does not include the text from inputs.
When a 'valid' copy event occurs, the following is sent to the dataLayer.
{
"event": "event_data",
"event_data": {
"event_name": "copy",
"type": "copy",
"action": "copy",
"method": "browser copy",
"text": "Some copied text",
"length": 245
}
}
The text attribute contains the first 30 characters of the copied text, with PII removed.
The length attribute shows the original number of characters that were copied.
