Dlaczego ten kod zwraca pusty alert ?

	var collection = $('input[id^="cartEditCustomWeight_"]');	
	var data = new Array();
	
	$.each(collection, function() {
		var id = $(this).attr('id').split('_')[1];		
		data["a"] = $(this).val();
	});
	alert(data);

Wstaw tutaj:

alert(collection.length);

Wówczas sprawdzisz czy w collection jest jakikolwiek element.

> var id = $(this).attr('id').split('_')[1];
> data["a"] = $(this).val();

> alert(data);
