Question

I won’t to write some values into database with ajax on submit event, after that I want to query the database (with ajax) once again to check for some response that will be written after the first ajax action. Last, if the response values are “ok” then I want to refresh the page, else I will make the query 2 secs latter till the response gets ok!

//Write into database form values on submit event
$('form').submit(function(){
    $.post("submitForm.php", { "array": submitedArray});

//HOW to verify if submited values where well written into databse? 
   return false;
});

//ONLY after submit I want to query the database and based on the response values I will refresh the page every two seconds (if response values not good) or refresh only once (if values checked are good)

var refresh = setInterval(function(){
      $.getJSON('someOtherScript.php', function(data){
         $.each(data, function(index, value){
           //Check values 
     });                    
      });
   }, 2000);

If I have this correctly, you are using ajax to submit the form and want to do the check on callback.

$.ajax({
  url: '/path/to/file',
  type: 'POST',
  dataType: 'xml/html/script/json/jsonp',
  data: {param1: 'value1'},
  complete: function(xhr, textStatus) {
    //called when complete
  },
  success: function(data, textStatus, xhr) {
    //called when successful
    // This is where you will do your get request to find the result you are looking for.
  },
  error: function(xhr, textStatus, errorThrown) {
    //called when there is an error
  }
});
