Login form in VBCS

Content

Hi, i'm looking to create an login page in vbcs. I've business object that has username and password stored. Now in my login page i have two fields username and password and login button. In button action i have entered js code in which username and password are hardcoded.

("if($SampletableEntityDetailArchetypeRecord.getValue('username')=='cloud.admin'

   && $SampletableEntityDetailArchetypeRecord.getValue('password')=='cloud')

{

  resolve($SampletableEntityDetailArchetypeRecord);

}

else{

  reject("Error");

}"

)

In this code now i want username and password to be derived from my business objects(username and password). if that matches it should navigate to other page.

How do i achieve this??
