A return value from an array and displaying a corresponding alert message
Hi guys,
This code is obviously wrong however I wanted to outline the aim of it.
After entering a value of say "4000" an alert box would come up and say "Your postage is...". If they entered a value of "2000" it would display another message which I haven't made up yet.
Basically after entering a value the script compares it to which array it is in and produces the corresponding message. Any ideas?
Thanks in advance,
A
<script language="Javascript" type="text/javascript">
var zoneChart = new Array;
zoneChart[0] = new Array("4000.4416","4418.4419","4421.4427");
zoneChart[1] = new Array("2000.2010","3000.3010");
var zoneChart = prompt("Please enter your postcode","")
if (zoneChart =="0")
{
alert("Your postage is $24.95 and delivery time is 2 days")
}
else
{
alert("Please enter a valid postcode")
}
</script>

could you explain further what your arrays contain? Also, if you are using STATIC data, then its best to use a switch.

Hey gRoberts,
The arrays contains values for example in the first array numbers between 4000-4416, 4418-449, 4421-4427. The second array holds values between 2000-2346.
The idea is is the user types in say 4001 it will return an alert box of "Your postage will be xxx amount etc. If the user types in 2000 *ie the second array* the alert box will be "Your postage will be a different amount".
I hope I have explained this moderately.

Right, well this could be recoded to be alot easier.
Unless there is a specific reason to have an array of arrays of post codes, then it should all be in one, and with that i've changed the array. It is now seperated by pipes (|) and also includes the message that will be displayed for anything between that range of post codes.
