Hi, I'm a beginner of JavaScript.
I need the code for creating pgv_pvid and ssid.
I had searched the web, and got some code, I wonder if the code is right:
var curDate = new Date();
var curMs = curDate.getUTCMilliseconds();
pgv_pvid = (Math.round(Math.random() * 2147483647) * curMs) % 10000000000;
ssid = "s" + (Math.round(Math.random() * 2147483647) * curMs) % 10000000000;
WScript.Echo(pgv_pvid)
WScript.Echo(ssid)js file:
