				<param name="allowedTypes">  
					image/bmp,image/png,image/gif,image/jpeg,image/jpg,image/x-png, image/pjpeg

jsp代码：

	<div style="width: 400px;height: 200px;border: 5px solid red;padding: 15px;">
		<form action="upload.do" method="post" id="upload" enctype="multipart/form-data"></form>
		<input type="file" name="icon" form="upload" />
		<input type="submit" value="上传" class="btn30" form="upload" />
		<input type="text" name="age" />
		<a href="upload.do">测试</a>
		<div id="msg" style="display: none">正在上传。。。</div>
	</div>
	<script type="text/javascript">
// 		function upload(){
// 			$.ajax({
// 				url:"upload.do",
// 				method:"post",
// 				dataType:'json',
// 				async:true,//false：同步，true为异步（默认）
// 				beforeSend:function(xhr){
// 					$("#msg").css('display','block');
// 				},
// 				success:function(data){
// 					alert(data);
// 					$("#msg").css('display','none');
// 					alert("上传成功");
// 				}
// 			});
		}
	</script>
