You don't have to do any of this. I ran into the same problem with my project. what you do is make a function call inside the on success callback to reset the global variable. As long as you got asynchronous javascript set to false it will work correctly. Here is my code. Hope it helps.

 var exists;

 //function to call inside ajax callback 
 function set_exists(x){
     exists = x;
 }

  $.ajax({
     url: "check_entity_name.php",
     type: "POST",
     async: false, // set to false so order of operations is correct
     data: {entity_name : entity},
     success: function(data){
     if(data == true){
        set_exists(true);
     }
     else{
        set_exists(false);
     }
  }
});

if(exists == true){
    return true; 
}
else{
    return false;
}

Hope this helps you .
