firefox 和 ie 的檔案類型區別

 

Firefox：	image/jpeg, image/bmp, image/gif, image/png
ie 6：	image/pjpeg ,image/bmp, image/gif, image/x-png
ie 7：	image/pjpeg, image/bmp, image/gif, image/x-png
ie 8：	image/pjpeg, image/bmp, image/gif, image/x-png
Ie 9：	image/jpeg, image/bmp, image/gif, image/png

 

所以在struts.xml設定檔中需要

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