How to do a AJAX query in php

Thank you,

I have tested this on my website and after one hour
looking for corrections I've managed to have a AJAX GET and POST
THANKS.
The problem with the code I find in books internet... I must always correct something
and loose time.

my comment

With the  link  http://api.jquery.com/jquery.ajax/ I found an example
which fails:


$.ajax({
  type: "POST",
  url: "some.php",
  data: { name: "John", location: "Boston" }
})
  .done(function( msg ) {
    alert( "Data Saved: " + msg );
  });


(
it seems the correct code is

 $.ajax({
  type: "POST",
  url: "some.php",
  data: { name: "John", location: "Boston" },
  success: function(data, textStatus, jqXHR)
    {
        alert(data);
    }
});

After 1 hour struggling I've managed to correct the sample code

 
)

but thanks to it I've been able to correct
the source code a little
$.get("data.php,  => $.get("data.php",
and in the second method you ommited
 data: { param1:"value1A", param2:123456 },

$.ajax({
    method: "GET", // or POST
    url: "data.php",
    success: function(data_or_message_from_data_dot_php) {
       alert( data_or_message_from_data_dot_php );
    }
})

=>

$.ajax({
    method: "GET", // or POST
    url: "data.php",
       data: { param1:"value1A", param2:123456 },
    success: function(data_or_message_from_data_dot_php) {
       alert( data_or_message_from_data_dot_php );
    }
      })
