asynchronous - Async run for javascript by using listeners -

i have 2 functions, names function3, function4, function3 send request server side jsondata using ajax, which, however, take 3 seconds complete. function4 common function wait function3's result , action. code puts below:

  function ajaxrequest(container)   {     $.ajax({         url: "home/getresult",         type: "post",         success: function (data) {             container.append(data.message);         }     });   }    var eventable = {     on: function (event, cb) {         $(this).on(event, cb);     },     trigger: function (event) {         $(this).trigger(event);     } }  var function3 = {     run: function () {         var self = this;         settimeout(function () {             ajaxrequest($(".container1"));             self.trigger('done');         }, 500);     } }  var function4 = {     run: function () {         var self = this;         settimeout(function () {             $(".container1").append("function4 complete");             self.trigger('done');         },500);     } }  $.extend(function3, eventable); $.extend(function4, eventable);  function3.on('done', function (event) {     function4.run(); });  function4.on('done', function () {     $(".container1").append("all done"); });  function3.run();

but problem is, when start code , show me result : first appear "function4 complete", "all done" follows, 3 seconds later, "function3 complete" appear.
that's out of expection because expection "function3 complete" comes first, "function4 complete" comes second , "all done" expected last one.

anyone can me on this? thx in advice.

edit:
have included functions above now.
also, can check js script in jsfiddle : http://jsfiddle.net/sporto/fybjc/light/
have replaced function in jsfiddle common array push action ajax request, things run out of expection.

you need call function4() within success-function follows ajax-request function3() makes. way function4 executed after function3.

and might suggest more suggestive function names:)

and don't think need timeouts then

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
