Use jQuery when

// Function to return id info based on this example http://stackoverflow.com/questions/5316697/jquery-return-data-after-ajax-call-success 
function getInfo(ID) {
return $.get("info?id=" + ID);  
}
// based on examples from https://api.jquery.com/jQuery.when/
var promises = [];
var jqxhr = $.get("activeIDs")
  .done(function(data) {
    $.each(data,function(i,v) {
        promises.push(getInfo(v));
    });
    $.when(promises).done(function(p) {
        console.log(p,p.length);
    });
  })
  .fail(function() {
    alert( "Error" );
  });
