iterating through Array

[joor]

Hi
I am new to all this so please excuse my ignorance. I am trying to work out how I can check if my Array contains my declared variable and if so, for the boolean to return true, however, I dont seem to be getting anywhere. I have tried the for loop and while loop as below; I would very much appreciate any help

[CODE=javascript]var customerCodes = ['sh-12', 'gw-4', 'to-0'];
var customerPasswor ds = ['tony', 'darma', 'checks', 'lauren'];

var password;
password = window.prompt ('enter password' + '')
var customerIndex;
customerIndex = 0;

for (var index =0; index < customerPasswor ds.length; index = index + 1)

while (password != customerPasswor ds[customerIndex])
{

window.prompt ('enter correct password' + '')

}

document.write ('lala')[/CODE]

some browsers implement an indexOf for array elements.
It is a handy method, you can add it if it isn't defined-
[CODE=javascript]if(Array.protot ype.indexOf== undefined){
Array.prototype .indexOf= function(what){
var L= this.length, i= 0;
while(i< L){
if(this[i]=== what) return i;
++i;
}
return -1;
}
}[/CODE]

Then you can see if any item is in any array-
if(customerPass words.indexOf(p assword) !=-1) // password found
or
if(customerPass words.indexOf(p assword) ==-1)// password not in array

thanks for your help,

I have taken a slight different route, however, I still seem to be stuck, what I am really trying to do is to create a while loop which will keep prompting me for the password if the password does not match the strings. also, if I had a parallel array, I would like to keep the index relevant to the password position. Any ideas?? Thanks again


[CODE=javascript]<script language="JavaS cript" type="text/JavaScript">

There's a pretty strict policy on homework/classwork assignments. See the guidelines. If this can be confirmed, the code can be dealt with accordingly.
