How it works

There are few functions in the script.js file.

1. btn.onclick event will call function to set the display property of the form modal to "block", basically from hidden to visible
2. setCriteria() is called when Confirm button is clicked, then form values are passed to predefined variables, and will call checkCriteria() function
3. checkCriteria() function will check whether use typed in a number that's within 8-128 range, and at least one of the character pools is selected, this function will return false if criteria is invalid, and return true is valid
4. writePassword() function will be executed if checkCriteria() returns true, and starts to call generatePassword() as well as closing the modal, displaying the password, copy to clipboard, and alert window message
5. generatePassword() is the one that generates the password text given the length, character pool selection
