Injecting text content copied from page

Question

I would like to know how to inject content into text copied from the page. When I copied a text from a website, it came along with an institutional text and the link from the website. You can see this happening on this website.

Answer 1

To do this you need to add an Event Handler to the event copy.

Inside that Handler you have to fetch the already selected text and then add the new part.

Example:

function addLink(e) {
    e.preventDefault();
    var copyright = ' - Ler mais aqui: www.google.com';
    var novoTexto = copytext = window.getSelection() + copyright;
    (window.clipboardData ? window : event).clipboardData.setData('Text', copytext);
}

window.addEventListener('copy', addLink);

In some browsers the clipboardData is a property of event, in IE is a property of window, hence the test window.clipboardData ? window : event
