I have some very basic Javascript that copies text upon the push of a button. My problem is that it doesnt preserve line breaks:

First off, the  element doesn't preserve line breaks. You can use the </code> element instead. Since your HTML may contain <code><br></code> elements instead of line break characters, I would also suggest using jQuery to prepend <code>\r\n</code> before each <code><br></code>.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function copyToClipboard(element) {
  var text = $(element).clone().find('br').prepend('\r\n').end().text()
  element = $('<textarea>').appendTo('body').val(text).select()
  document.execCommand('copy')
  element.remove()
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p contenteditable="true">Type to edit <br> this text</p>
<button onclick="copyToClipboard('p')">Copy to Clipboard</button></code></pre>
