If you need to extract text from a data-title attribute, one approach is to utilize the getAttribute method in JavaScript for fetching the content from the attribute, followed by employing the execCommand method along with the 'copy' parameter to replicate it onto the clipboard. Check out the code snippet below for a demonstration:
// Locate the element containing the data-title attribute
var element = document.querySelector('[data-title]');
// Retrieve the text stored in the data-title attribute
var text = element.getAttribute('data-title');
// Transfer the text to the clipboard
document.execCommand('copy', false, text);
Remember that this technique will only function if there has been user interaction on the page, like clicking on an element, to initiate the execution of the JavaScript code. It's also worth noting that certain browsers may necessitate user consent for accessing the clipboard.
