Answer 1

Try to use the below code :

    function myajaxcall(id){

new Ajax.Request('a.php?id='+id, {
  method:'get',
  onSuccess: function(data) {
    var response = data.responseText || "no response text";
    alert("Success! \n\n" + response);
  },
  onFailure: function() { alert('Something went wrong...'); }
});
}
