jquery - Redirect on success and show error on failure -

i have implemented controller create new users. when creates user redirects index().

what want get redirected when ok, stay in current page , see error when failed.

i'm using jquery ajax mvc.

my controller looks this:

[authorize] public actionresult createuser(string username) {     try     {         //here logic create user     }        catch (exception ex)     {         string error = string.format("error creating user: {0}", ex.message);         response.statuscode = 500;         response.write(error);         }     return redirecttoaction("index"); } 

the form submit intercepted jquery, , call made ajax:

$("#new-user-form").submit(function() {     var form = $(this);     $.ajax({     type: "get",         url: form.attr('action'),         data: form.serialize(),         success: function(data, textstatus, xhr) {             //at point redirect         },         error: function(xhr, textstatus, errorthrown) {             $(".error-summary").html(xhr.responsetext);         }     });      //cancel event     return false; }); 

it works fine when error occurs, don't know how implement success case.

i'm opened other alternatives.

if going redirect in success action why using ajax? purpose of ajax refresh parts of site without reloading whole page. if in success action going redirect totally defeats purpose , benefits ajax. because asked here's do:

[authorize] public actionresult createuser(string username) {     ...     if (request.isajaxrequest())     {         return json(new { redirecttourl = url.action("index") });     }     return redirecttoaction("index"); } 

and then:

success: function(data, textstatus, xhr) {     window.location.href = data.redirecttourl; },
