JavaScript - Everything to the left and right of "-"

I need to break apart a string - if it contains a "-"
Then I need to get one value with everything to the left of the dash and then another, with everything to the right of the dash?

Something like this?

var hyphenIndex = str.indexOf("-");

if (hyphenIndex >= 0)
{
    var left = str.substring(0, hyphenIndex);
    var right = str.substring(hyphenIndex + 1);
}

You could also use split:

var str = 'something - something_else';
var substr = str.split('-');
// substr[0] contains "something"
// substr[1] contains "something_else"

If there were more than one hyphen, your array will hold that many more substrings.

var str = 'something - something_else - and another thing';
var substr = str.split('-');
// substr[0] contains "something"
// substr[1] contains "something_else"
// substr[2] contains "and another thing"

Also, you can check if there is a hyphen to begin with. I did not include that code. You can do that kaufmed's way, or use a regex, it's up to you...

and just to clarify, if there was no hyphen substr[0] would return the original string.

also, using split, you can retrieve the length of the substring array and display that many results using a for loop.
