JS or Prototype: Break string into two variables

Say I have a load of strings that follow the same sort of struct开发者_如何学Cure as this:

Outcome 1: - Be able to create 2D animations for use as part of an interactive media product.

I want to get everything before the '-' and put it into one variable, and everything after the '-' and put it into another variable. So output is as so:

$1 = "Outcome 1";
$2 = "Be able to create 2D animations for use as part of an interactive media product.";

Thanks

(Also does anyone know how I would then remove the title tag from the following selector?

  $$('span[title]').each(function(element) {
});

You can split a string using regular expressions. In your case, you want to:

1. Get rid of the colon (:)
2. Get rid of the extra space surrounding the dash (-)

So:

var tokens = s.split(/:\s*-\s*/);
// tokens[0] will be the first part
// tokens[1] the second

var string = "Outcome 1: - Be able to create 2D animations for use as part of an interactive media product."

var strArr = string.split("-");

RESULTS:

strArr[0] == "Outcome 1: "
strArr[1] == " Be able to create 2D animations for use as part of an interactive media product."

This regex will remove the trailing colon on the first element and any whitespace surrounding the dash as well:

var parts = str.split(/\s*:\s*-\s*/);
parts; // => ['Outcome 1', 'Be able to create...']
