Check the login
önem: 3
Write the code which asks for a login with prompt.
If the visitor enters "Admin", then prompt for a password, if the input is an empty line or Esc – show “Canceled.”, if it’s another string – then show “I don’t know you”.
The password is checked as follows:
- If it equals “TheMaster”, then show “Welcome!”,
- Another string – show “Wrong password”,
- For an empty string or cancelled input, show “Canceled.”
The schema:
Please use nested if blocks. Mind the overall readability of the code.
Hint: passing an empty input to a prompt returns an empty string ''. Pressing ESC during a prompt returns null.
let userName = prompt("Who's there?", '');
if (userName == 'Admin') {
let pass = prompt('Password?', '');
if (pass == 'TheMaster') {
alert( 'Welcome!' );
} else if (pass == '' || pass == null) {
alert( 'Canceled.' );
} else {
alert( 'Wrong password' );
}
} else if (userName == '' || userName == null) {
alert( 'Canceled' );
} else {
alert( "I don't know you" );
}Note the vertical indents inside the if blocks. They are technically not required, but make the code more readable.
