<head> <title>Untitled Page</title></head><body>
<script type="text/javascript">
function preview(fileupload)
{
var image = document.getElementById("image"); image.src = fileupload.value; image.style.height = "200px"; image.style.width = "200px";
}
</script> <img id='image' alt='image' src='' /> 这里fileupload也是适用的，用onchange方法，虽然会报不符合XHTML1.0 <input id="File1" type="file" onchange="preview(this)"/></body></html>
