jquery - Delay Javascript button onClick using setTimeout -

i'm having problem delaying button click. i've searched through stackoverflow , i've found couple answers , it's easy enough settimeout can't work in i'm working on. here's sample of code:

ajax submits data database on submit button click

<script>   $(function () {     $('form').on('submit', function (e) {       $.ajax({         type: 'post',         url: 'post.php',         data: $('form').serialize(),       });       e.preventdefault();     });   }); </script> 

pusher code

<script>     $(function() {      var pusher = new pusher('pusher')     var activitychannel = pusher.subscribe('stream');     var activitymonitor = new pusheractivitystreamer(activitychannel, "#current");      var examples = new exampleactivities(activitymonitor, pusher);      $("#broadcast").click(function(){         activitymonitor.sendactivity('broadcast');     });     $("#submit").click(function(){         activitymonitor.sendactivity('submit');     });     }); </script> 

html buttons

<input id="submit" name="submit" type="submit" value="submit" onclick="addmem()"><br> <button id="broadcast">broadcast</button> 

the onclick="addmem()" on submit button script. it's pretty busy button.

so what's happening click submit , ajax script pushes data post.php submits database. same submit click pusher code triggered pulls submitted data out of database , broadcasts that's connected.

the problem i'm having submit submits data database , triggers pusher pulls database simultaneously. 75% of time pusher code tries pull data database before submit has submitted it.

i put settimeout everywhere think of , couldn't delay pusher code. suggestions? it's ok if submit , broadcast buttons delayed. it's not ok if clicking submit delays ajax code or onclick=addmem()

sorry making complicated. final step of long project , if can working it's css, data entry , math here.

i suggest passing success callback jquery.ajax method trigger broadcasting so:

$.ajax({   type: 'post',   url: 'post.php',   data: $('form').serialize(),   success: function () {     activitymonitor && activitymonitor.sendactivity('broadcast');   } }); 

a solution settimeout this:

$("#broadcast").click(function(){     settimeout(function () { activitymonitor.sendactivity('broadcast') }, 2000); });
