Currently my code looks like:
var how_many = "";
$.ajax({
type: "POST",
url: "/ajax_add_selected_product_to_session.php",
success: function(msg){
/* add here what to do on success */
//alert(msg);
how_many = msg;
}
});
if($("input[name^='paradigm']:checked").length == 0) {
//alert('None are checked on page');
$(".requestbutton").attr("disabled", "disabled");
}else{
//alert('At least one is checked');
$(".requestbutton").removeAttr("disabled");
$(".requestbutton").click(function(){
$("#list").submit();
});
}
But I still can't access the var how_many.
I would like to do this: ($("input[name^='paradigm']:checked").length
== 0 || how_many == 0) {
But the how_many is not set... it's empty on alert. Not undefined,
it's empty..
*i am lost...*
