Question

How can I detect vertical text overflow in a div element?

CSS:

div.rounded {
   background-color:#FFF;
   height: 123px;
   width:200px;
   font-size:11px;
   overflow:hidden;
}

HTML:

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

Answer 1

You can easily do that by comparing scrollHeight with clientHeight, try the following:

<script type="text/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);
}
</script>
