Jquery checkbox級聯選擇 -- 通用型

/*checkbox 上需要添加index字段  格式如下：父節點為1則子節點為1_1，1_2 以此類推*/$j(function($) {$(":checkbox").click(function(){var index = $(this).attr("index");$(":checkbox[index^="+index+"]").attr("checked",$(this).is(":checked"));var parent_index = index.substring(0,index.length - 2);$(":checkbox[index="+parent_index+"]").attr("checked",false);var parentIsCheck = false;$(":checkbox[index^="+parent_index+"]").each(function(i){if($(this).is(":checked")){parentIsCheck = true;}});$(":checkbox[index="+parent_index+"]").attr("checked",parentIsCheck);var parent_parent_index = index.substring(0,parent_index.length - 2);var parent_parent_is_check = false;$(":checkbox[index="+parent_parent_index+"]").attr("checked",parent_parent_is_check);$(":checkbox[index^="+parent_parent_index+"]").each(function(i){if($(this).is(":checked")){parent_parent_is_check = true;}});$(":checkbox[index="+parent_parent_index+"]").attr("checked",parent_parent_is_check);});});

關鍵在於index 這個字段 --  js代碼只不過是判定而已~~~
