JavaScript: String extraction

Question

If my String is like this:

var dollarValue = "$7.50;$15;50%";

What would be the best method of extracting each value? Each semicolon is used as a separator between the part of the string that matters. So like:

$7.50

$15

50%

I understand how to extract two values with only one semicolon, but I'm not sure how I would continue on down the string using each subsequent semicolon as the next starting point...

How 'bout String.split()?

var arrayOfValues = dollarValue.split(";"); // ["$7.50", "$15", "50%"]

Does split just take the ";" and enter it into an array of it's own? I would then extract the information out of that newly created array, right?

@dcolumbus: arrayOfValues[0] will be "$7.50", arrayOfValues[1] will be "$15", etc. just like arrays work.

It will basically cut the string up on every semicolon, returning an array of the parts.

Perfect. It's these little things that I forget over time when I'm not constantly using it. Learning too many languages scrambles my brain.

You can use the split method:

var values = dollarValue.split(";");

This will return an array with the values between the semicolons.
