Facebook Javascript API SDK and Init method -


i use start sdk of api js of facebook :

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">     <head>         <meta http-equiv="content-type" content="text/html; charset=utf-8" />         <title>documento sin título</title>     </head>     <body>         <script type="text/javascript">             window.fbasyncinit = function() {                 fb.init({                              appid:'<?php echo $appf['id'];?>',                     channelurl:'<?php echo $appf['url'];?>',                     status:true,                     cookie:true,                     xfbml:true                 });                 function test() {                     alert("okokok");                     }             }         </script>         <script>             (function() {                 var e = document.createelement('script');                 e.type = 'text/javascript';                 e.src = document.location.protocol +                 '//connect.facebook.net/en_us/all.js';                 e.async = true;                 document.getelementbyid('fb-root').appendchild(e);             }());         </script>         <a href="#" onclick="test()">active alert test</a>     </body> </html>

my problem it´s need insert functions login of facebook , if put code inside of fb.init , never works in example , functions works outside of fb.init

i don´t understand why happend because functions example :

fb.getloginstatus(function(response)

works inside fb.init

i understand did bad getting errors because have little function login , inside of fb.init no works

scoping, syntax , teh rulez

test() illegitimate child of fbasyncinit() child of window.

if idea alert when clicking element - if fbasyncinit() initialised - you'd better off testing property...

window.foo = function() { var bar = "baz"; }; window.test = function() {     if ( typeof foo === "function" ) {         alert( "whoot!" );     } else {         var oh_nose = true;     } }

...or similar.

then call test() - child of window - when clicky element gets poked.

notice that:

calling alert() - child of window - works same way. can argued (and is) correct way call alert() calling window.alert( "whatever" );.

an aside

consider using html5 via <!doctype html>

an answer on question more details.
