推荐答案

尝试这些

检查FileUpload控件的文件扩展名 [如何检查上传文件扩展名(JavaScript) [ ^ ]

Try these

Check file extension of FileUpload control[^]
How to check upload file extension (JavaScript)[^]

您可以使用MSDN链接中提供的脚本，然后检查将图像传递到的img标签是否大于0x0(即在).

You may be able to use the script giving in the MSDN link and then check if the img tag you pass the image to, is bigger than 0x0 ( i.e. has an image in it ).
