提供用户名和一个随机密码，但这个密码是如何产生的，现在我就向大家来介绍一下 请看下面的例子，用户可自行增加或减少随机的字符或数量。 <% Function gen_key(digits) "Create and define array dim char_array(50) char_array(0) = "0" char_array(1) = "1" char_array(2) = "2" char_array(3) = "3" char_array(4) = "4" char_array(5) = "5" char_array(6) = "6" char_array(7) = "7" char_array(8) = "8" char_array(9) = "9" char_array(10) = "A" char_array(11) = "B" char_array(12) = "C" char_array(13) = "D" char_array(14) = "E" char_array(15) = "F" char_array(16) = "G" char_array(17) = "H" char_array(18) = "I" char_array(19) = "J" char_array(20) = "K" char_array(21) = "L" char_array(22) = "M" char_array(23) = "N" char_array(24) = "O" char_array(25) = "P" char_array(26) = "Q" char_array(27) = "R" char_array(28) = "S" char_array(29) = "T" char_array(30) = "U" char_array(31) = "V" char_array(32) = "W" char_array(33) = "X" char_array(34) = "Y" char_array(35) = "Z" "Initiate randomize method for default seeding randomize "Loop through and create the output based on the the variable passed to "the function for the length of the key. do while len(output) < digits num = char_array(Int((35 - 0 + 1) * Rnd + 0)) output = output + num loop "Set return gen_key = output End Function "Write the results to the browser, currently setting a 13 digit key response.write "<pre>" & gen_key(13) & "</pre>" & vbcrlf %> 源代码网供稿. |
