A more recent solution (year 2020) uses the new Clipboard API writeText method which is supported by most modern browsers (see Can I use for more details).

//If you want to copyText from Element
function copyTextFromElement(elementID) {
  let element = document.getElementById(elementID); //select the element
  let elementText = element.textContent; //get the text content from the element
  copyText(elementText); //use the copyText function below
}

//If you only want to put some Text in the Clipboard just use this function
// and pass the string to copied as the argument.
function copyText(text) {
  navigator.clipboard.writeText(text);
}

This is some text that needs to be copied
