var num = 5;   
 for (m = 1; m <= num; m++) {
            if (m % 2 == 1) {
                p = 1;
                q = 1;
            } else {
                p = "*";
                q = "*";
            }
            for (n = 1; n <= m; n++) {
                if (n % 2 == 0) {
                    document.write("" + p + " ");
                }
                else {
                    document.write("" + q + " ");
                }
            }
            document.write('<br/>');
        }  

Where 1 is printed, one number after another should be printed How can I do that?
