完整解決代碼在7F
-------------------------
请教各位大神小弟第一次接触到JS
很多不懂意思只能猜测..
还请多多指教，感谢~
以下JS要如何调用才有效果呢？
功用是 生成 TOTP 6位数金钥，30秒刷新一次
我的测试1#include <Date.au3>
Func js()
Local $code
;;TOTP公式 TOTP(K,C)
;;K = Key
;;C = (T - T0) / X
;;T = Unix时间戳
;;T0 = 0 (起始值)
;;X = 30 (30秒刷新一次)
$T = _DateDiff('s', "1970/01/01 08:00:00", _NowCalc())
$X = 30
$K='LFLFMU2SGVCUIUCZKBMEKRKLIQ'
$C = $T / $X
$code = FileRead("totp.js")
$nJS = ObjCreate("MSScriptControl.ScriptControl")
$nJS.language = "JavaScript"
$nJS.addcode($code)
$nReg = $nJS.eval('function HOTP("'&$K&'","'&$C&'")')
Return $nReg
EndFunc ;==>js
MsgBox(0,0,js())
$nJS.addcode($code)
$nJS^ ERROR
测试2;以下是使用JavScript代码调用
