解决方案
你可以用javascript实现这个，你必须使用'offsetHeight'方法。
function getHeight（）{
var height = document.getElementById（'test'）。offsetHeight ;
alert（height）;
Anybody knows why the following code fails to work? I need a dynamic height for a fixed width div that may descend below past the viewport.
<script type="text/javascript">
function findheight(){
var div = document.getElementById('bg');
var height = document.scrollHeight;
div.style.height = height + 'px';
}
</script>
</head>
<body onload="findheight()">
<div id="bg">
Is there another way around this if not?? Any help is appreciated. Thanks
解决方案
You could achieve this using javascript, you have to use the 'offsetHeight' method.
function getHeight() {
var height = document.getElementById('test').offsetHeight;
alert(height);
}
