The element is at root level, and the contex selector uses find() internally, and that only works on descendants.

You can avoid any and all issues with elements being descendants or at root level by appending the content to another element, and then using find(), or you could use filter() directly

 $.get('load_list.php', function(data){
    var values =  $('<div />', {html: data}).find("input[name='total']").val();
    alert(values);
 });

Also, the element has an ID, and it would be more efficient to use that in the selector.

You're in kind of a bad situation since you're just reloading the list after 3 seconds even if the call failed. You should try to clean up the whole idea a bit.

function reloadList = setTimeout(function(){
  $.get('load_list.php', function(result){
    var value = $(data).filter('#total').val();
    alert(value);
    reloadList();
  });
}, 3000);

reloadList();
