Split Command

[Mighty]

Guys,

I know this is a bit of a simple question to ost but i don't have any JS reference material on hand and I can't locate this on the web.

Can someone please give me an example of the split command. Actually maybe there's a better way of doind what I want to do. i will have a text field and when it displays it will have a $ in it. When the form is submitted, I want to verify that the user has entered a number. So I was going to use split ot get rid of the $ and then verify that the array element was a number.

Any other suggestions are welcome. Mise Le Meas,

Mighty

Syntax
--split(separator, limit)
Parameters
--separator (Optional) Specifies the character to use for separating the string. The separator is treated as a string. If separator is omitted, the array returned contains one element consisting of the entire string.

--limit (Optional) Integer specifying a limit on the number of splits to be found.

example:

function splitString (stringToSplit,separator) {
arrayOfStrings = stringToSplit.split(separator)
document.write ('<P>The original string is: &quot;' + stringToSplit + '&quot;')
document.write ('<BR>The separator is: &quot;' + separator + '&quot;')
document.write (&quot;<BR>The array has &quot; + arrayOfStrings.length + &quot; elements: &quot
}

here's the best online reference I've found for javascript (and where I cut and pasted this from)

then you can ask if isNan(number) -- but you probably knew that...

good luck!
