这个功能貌似没有吧!!这个是浏览器控制的!如果要限制上传类型的话可以通过上传文件的$_FILE['name']['type']进行判断!
对应的类型参考如下 private static $i_mine = array(
'application/rar'=>'rar',
'application/x-rar-compressed'=>'rar',
'application/arj'=>'arj',
'application/excel'=>'xls',
                                'application/vnd.ms-excel'=>'xls',

                                'application/x-tar'=>'tar',
                                'application/x-gtar'=>'gtar',
'application/octet-stream'=>'dat',

                                'application/vnd.ms-powerpoint'=>'ppt',

                                'application/mac-binhex40'=>'hqx', 
                                'application/x-stuffit'=>'sit', 
                                'application/x-macbinary'=>'bin',

用js的话只能通过后缀名来判断 实际类型还要通过php来判断
