  i don't know about how to connect database through javascript but can provide you a simple method
  just create a function check()
  in that create a array that will store userid;
  now when ever user submit form then call that function and compare userid with every
  
  element of array if there is a match then it will be successful
  
  Just give it a try if you face any problem then post it here
