Using Regex to extract value from javascript

How can I use regex to parse the numeric value (104) assigned to qtyAvail in the below javascript?

<script>
var buyID       = "302";
var qtyAvail    = "104";
var outBehavior = "Default";
if (qtyAvail == "0") {
    if (outBehavior.indexOf("Disallow") != -1) {
        do this
    } else if (outBehavior.indexOf("Allow") != -1) {
        do that
    }
}
</script>

You don't need to use a regular expression, you can just use the native parseInt javascript function:

parseInt(qtyAvail, 10); // the 2nd argument 10 means use base 10 (decimal, as opposed to hexadecimal or something else)
=> 104
