JavaScript에서 텍스트 콘텐츠가 DIV 요소를 오버플로하는지 어떻게 확인할 수 있나요?

<code class="html"><div id="tempDiv" class="rounded">
  Lorem ipsum dolor sit amet,
  consectetur    adipiscing elit. Phasellus vel quam vestibulum orci blandit laoreet.
</div></code>

<code class="css">div.rounded {
  background-color: #FFF;
  height: 123px;
  width: 200px;
  font-size: 11px;
  overflow: hidden;
}</code>

<code class="javascript">function GetContainerSize() {
  var container = document.getElementById("tempDiv");
  var message = "The width of the contents with padding: " + container.scrollWidth + "px.\n";
  message += "The height of the contents with padding: " + container.scrollHeight + "px.\n";

  alert(message);
}</code>
