            $.each(arr1, function(i, val) {
                console.log(i + val);
            });

            var arr2 = [
                ['a', 'aa', 'aaa'],
                ['b', 'bb', 'bbb'],
                ['c', 'cc', 'ccc']

            $.each(arr2, function(i, item) {
                console.log(i + "====" + item);
                $.each(item, function(j, val) {
                    console.log(j + "====" + val)
                });
            });

            //处理json数据

                one: 1,
                two: 2,

                console.log("i===" + i)
                console.log(val.name)
                console.log(val.value)
