Call with copy2Clipboard(event, mode, text[, html]) where

• event is the triggering user event (for example, a button click); this is used when the user's Clipbord API is disabled and the event.clipBoardData method is used as a fallback
• mode is the desired formatting mode:
  • "txt" if only the text/plain MIME type should be set
  • "fmt" if both text/plain and text/html MIME types should be set
• text is the plaintext that shall be copied to clipboard
• html (optional) is the HTML equivalent that shall be copied to clipboard; if the parameter is not specified, text is set as html content

For example:

$(button).on('click', (ev) => {
copy2Clipboard(ev, "fmt", "hello world", "<strong>hello world</strong>");
});
