Calling Ajax method using javascript function -

i'm working jquery mobile.
my code move details div ::

<a href="#details" data-ajax="true" data-transition="pop" data-role="button" data-inline="false" data-icon="info">go details</a> 

now, want authenticate user facebook.

so have applied ::

<a href="javascript:userlogin()" data-ajax="true" data-transition="pop" data-role="button" data-inline="false" data-icon="info"> login faceook </a> 

function calling authentication

function userlogin() {      fb.login(           function(response) {                if (response.authresponse) {                    alert('logged in');                     fb.api('/me', function(response) {                      alert("welcome " + response.name);                    });                 } else {                    alert('not logged in');                 }            },            { scope: "email" }      ); } 

i'm getting valid user response after authentication.
now want navigate details div.

so, how can implement ajax code after login ??
any suggestion appreciated.

thanks.

instead of changing href attribute directly, should bind onclick event function returning true.

modify a tag.

<a href="#details" onclick="javascript:return userlogin()" data-ajax="true" data-transition="pop" data-role="button" data-inline="false" data-icon="info">go details</a> 

modify userlogin function:

function userlogin() {     fb.login(         function(response) {             if (response.authresponse) {                 alert('logged in');                  fb.api('/me', function(response) {                     alert("welcome " + response.name);                 });             } else {                 alert('not logged in');             }         },         { scope: "email" }     );     return true; } 

it seems fb.login asynchronized operation. if want redirect after login action, try modify location.hash after login. note return value has changed false.

function userlogin() {     var hash = '#details';     fb.login(         function(response) {             if (response.authresponse) {                 alert('logged in');                 fb.api('/me', function(response) {                     alert("welcome " + response.name);                     window.location.hash = hash;                 });             } else {                 alert('not logged in');             }         },         { scope: "email" }     );     return false; }
