Please help a newbie...

[Al Murphy]

Folks,

I've been given a heads-up on a Javascript project that I have to
do. As I'm a wee bit new to Javascript I'm wondering can you help me
please?
As part of the functionality of this project I have to do the
following:

1. Make a call to a remote box and cache some data on the page (I
believe JS can do this)

2. Extract a substring from a string

3. Detect a particular string and make decisions based upon it's value
(bunch of if-else statements)

Part 3 - I don't have any problems with. But part 1 and 2 is a bit
more challenging.
Can anyone offer any suggestions/comments/code snippets etc... on
either part 1 or 2 please?

Thanks a million,
Merci,
Al.

What is a "remote box"?

A candy container in the Sahara ?

2. Extract a substring from a string

myResult = myString.substr(2,7)

It *may* be possible to do this. See

2. Extract a substring from a string

That's simple enough:

string.substring(s, e)

where s and e are zero-order numbers; s denotes where extraction should
begin, and e specifies the (non-inclusive) end-point. For example:

'together'.substring(2, 5)

returns 'get'. Note that the string doesn't get modified; a new string is
returned.

Hope that helps,
