Question

i am trying to use the Jquery ajax function to call a php page to run a query and return xm the only problem is i dont know how to read the Jquery API page

http://api.jquery.com/jQuery.ajax/

    $(this).addClass("done");
  }});

is there a better example to call a php page to run a sql query and return a json i can encode

Answer 1

See http://api.jquery.com/jQuery.getJSON/ . For example…

The PHP…

<?php
// users.php
$some_users = array(
                   array('name' => 'Nobby Clark', 'email' => '[e-mail]'),
                   array('name' => 'John Doe', 'email' => '[e-mail]'),
              );
print json_encode($some_users);
?>

The Javascript…

$.getJSON('users.php', function(data) {
    var users = "";
    for ( var i = 0; i < data.length; i++ ) {
        users += "<p>" + data[i].name + " (" + data[i].email + ") </p>";
    }
    $('.userlist').html(users);
});
