Sorry, another question... I just playing arround with different
possibilities:
$(document).ready(function(){
// on default, disable the submit button
$(".requestbutton").attr("disabled", "disabled");
function check_how_many_products_checked(){
$.ajax({
type: "POST",
url: "/ajax_add_selected_product_to_session.php",
success: function(msg){
/* add here what to do on success */
return msg;
}
});
}
var x = "";
x = check_how_many_products_checked();
alert(x);
The alert is always "undefined"...
Why? I must return the figure 2, what it does, if I alert the msg
directly.
Sorry for these questions, I am just about to learn the syntax.
Thanks!
