jquery checkbox的選中問題

var s_manageSeed = "";
	$(".list").find("input:checked").each(function() {
		//console.log($(this).attr("checked"));
		//if ($(this).attr("checked") == true) {
			s_manageSeed = s_manageSeed + $(this).closest(".wuyu").html().replace('<input type="checkbox" value="">', "") + " ";
		//}
	});
