Arrays

Suppose i have an array a:

a[n] = n + b * c, i - p

or simply

a[n] = g, h

how can i make it

a[n] = h.

In other words, how do I take out the g and the ",". ?

And after take out g and the ",", suppose h = " hi", how do you take out the extra spaces before the hi.

Thank you.

Code:

---

var b = a[n].split(',');
if (b.length > 0) {
    var c = b[1];
    while (c.indexOf(' ') == 0) {
        c = c.substr(1, c.length - 1);
    }
    a[n] = c;
}
