[jQuery] Re: Global variables in jQuery

[Mike Nichols]

'price' value won't be set until the callback completes, so try this:
unction calc_matrix(x, y)
{
        loc = "index.php?module=product";

        var price = 0;
        $.post(loc,
        {
                "request":"xmlhttp",
                "action":"calc_pricematrix",
                "x":x,
                "y":y
        },
        function(data)
        {
                price = Math.round(parseFloat(data)*100)/100;
                alert(price);
        });
