jquery - Change iFrame src on ajax complete -

-

using jquery's $.ajax() want retrieve information server, , then, based on info, change src attribute of iframe.

something like:

$.ajax(                 {                     url: "someurl.aspx/getinfo",                     datatype: "json",                     data: "{'data':{'data1':'data1'}}",                     type: "post",                     contenttype: "application/json; charset=utf-8",                     complete: function(data, stat) {                         if (stat == "success" )                          {                            var src = json.parse(jsondata.responsetext).d.src                            $('#myframe').attr("src",src);                         }                       }                 }                 );

the page trying load returning pdf file, goal show user dialog choose between downloading or opening file. on ie7 , 8 browser showing info bar message : "to protect security, internet explorer blocked site downloading files computer. click here options."

changing iframe's src attribute outside ajax call works fine , dialog choose between opening or saving pdf shown.

any workarounds avoid info bar showing? in advance.

an alternate approach avoids both iframe , info bar not open pdf automatically. in call ajax callback, create regular link pdf file user can click on directly. should prevent ie flagging download.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
