Guys i need help woth javascript


OSNN Junior Addict
Ok i know this is too much to ask, but i have to create this login page here's a description

A GUI login screen is to be displayed with the following GUI objects:

- userID text box named "txtUserID"
- password text box named "txtpassword"
- login button to call "authenticate(userIn, passIn)" named "btnLogin"
- appropriate prompts and messages

create the code in three modules (files):

- displays the GUI login screen

init.js (instead of owners.js, managers.js)
- initializes variables
- populates data arrays
the data for these will be provided as two lists of names & passwords
one list will contain names of managers and the other will be owners

- holds the functions
1. authenticate(userIn, passIn)
2. goToURL(nextWebPage)

Description of the Login authentication program:

We need to identify the user type as manager, owner or ordinary

when the user attempts to log in to the system
- the lists of users is searched for a match with the userID
- if a match for userID is found, the pIN is checked
if the pIN is correct the user is admitted to the system either as a manager or an owner
- otherwise the user is prompted to check the userID and pIN or to proceed to the ordinary user's page


authentication = the user's userID and pIN are verified
attempt to log in = user enters userID and pIN
userID = 3 to 14 characters
pIN = 4 digit number
admitted to the system as owner = display Owner's Welcome page
admitted to the system as manager = display manager's Welcome page
Suggested steps for the solution:

1. Store userID's and PIN's in parallel arrays or a single object array;

example of parallel arrays

userID = new Array("Fred", "Sally", "Judy");
pIN = new Array( 0000, 1111 ,2222);

2. get the items entered by the user from the form; eg.

onClick= "authenticate(user, pin)"

3. Search the userID array for a match; eg.

for (i = 0; i < userID.length; i++)
{ if (userID == user)
{ processPin;
... and so on

Suggested preliminary steps:

-2. experiment with getting data from a form

-1. experiment with the arrays of users; eg.
display their userID's and pIN's on the screen
with a function called displayUsers()

function displayUsers()
{ document.write("Number userID pIN ");
for (i = 0; i < userID.length; i++)
{ document.write(i + ". " + userID + " " pIN + "."); }

does anyone know where i can find soething that wud help me with this, or could anyone here help me with this? Thx in advance
