代码如下:
<style type="text/css"> #newPreview { filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=images); } </style> <script type="text/javascript" language="javascript"> function PreviewImg(imgFile) { var newPreview = document.getElementById("newPreview"); newPreview.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = imgFile.value; newPreview.style.width = newPreview.offsetWidth /2; newPreview.style.height = newPreview.offsetHeight / 2; newPreview.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").sizingMethod = 'scale'; } </script>
代码如下:
<input type="file" size="20" onchange="javascript:PreviewImg(this);" /> <div id="newPreview"></div>
