jquery - Ajax call throwing an error but I see response on Fiddler -


my page using ajax call username. see response in fiddler still throws error.

here code:

$.ajax({                type: "post",                url: "selection.aspx/getuser",                data: "{}",                contenttype: "application/json; charset=utf-8",                datatype: "json",                success: function (response) {                    var username = response.d;                    if (username.indexof("error") > 0) {                        jalert(username);                    }                    else                    {                        if( username!= "" )                         {                            $("#maincontent_lbluser").text(username);                        }                    }                 },                error: function (xhr, status, error) {                    if (xhr.responsetext != "") {                        var err = eval("(" + xhr.responsetext + ")");                        jalert(err.message);                    } else                        jalert('unable user', 'ajax error', null);                }            });

i see alert "unable user". in fiddler see {"d":"domain\crm.admin"}

any appreciated.

make sure returning json object. if aren't sure edit datatype specification , add code in success callback; example:

$.ajax({                type: "post",                url: "selection.aspx/getuser",                data: "{}",                contenttype: "application/json; charset=utf-8",                                  success: function (response) {                    newresponse = jquery.parsejson(response);                    var username = newresponse.d;                    if (username.indexof("error") > 0) {                        jalert(username);                    }                    else                    {                        if( username!= "" )                         {                            $("#maincontent_lbluser").text(username);                        }                    }                 },                error: function (xhr, status, error) {                    if (xhr.responsetext != "") {                        var err = eval("(" + xhr.responsetext + ")");                        jalert(err.message);                    } else                        jalert('unable user', 'ajax error', null);                }            });

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
