如何检测div元素中的垂直文本溢出?
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>
回答:
您可以通过将scrollHeight与clientHeight进行比较轻松地做到这一点,请尝试以下操作:
<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>
