Seeking assistance with my JS...please!

**SimpleCustomer** · Feb 4th, 2013, 12:39 PM

I'm trying to get it to prompt for hours worked, then rate per hour...which works fine. Then I cannot get it to display the adjusted pay when taxes are deducted. Any assistance is appreciated.

See if this works the way you expected it to.

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>SimpleCustomer</title>
        <script type="text/javascript">
            function calcPay(hours, rate){
                var regTime = 40;
                var overTime = 1.5;
                var calcPay;

                if (hours > regTime)
                    calcPay = regTime * rate + ((hours - regTime) * (overTime * rate));
                else
                    calcPay = hours * rate;
                    
                return calcPay.toFixed()
            }

            function adjCalcPay(calcPay){
                var fedTaxes = 0.31; 
                var stateTaxes = 0.08;
                var localTaxes = 0.02;
                var takeHome = calcPay - ((calcPay * fedTaxes) + (calcPay * stateTaxes) + (calcPay * localTaxes));

                return takeHome.toFixed()
            }

        </script>
    </head>
    <body>
        <h1>SimpleCustomer test</h1>
        <script type="text/javascript">
            var hours = prompt("Enter hours worked","");
            var rate = prompt("Enter hourly rate","");
            var calcPay;
            var takeHome; 

            calcPay = calcPay(hours, rate);
            takeHome = adjCalcPay(calcPay);

            document.writeln("Gross pay after working " + hours + " hours with pay rate of $" + rate + " per hour, will be $" + calcPay + ".");
            document.writeln("<br />");
            document.writeln("Take home pay after working " + hours + " hours with pay rate of $" + rate + " per hour, will be $" + takeHome + " after taxes.");
        </script>

    </body>
</html>

The main fix in the code is this line
takeHome = adjCalcPay(calcPay);

You had
takeHome = adjCalcPay(fedTaxes, stateTaxes, localTaxes);

The problem there is the adjCalcPay function is expecting a single parameter (the pay amount) but you are trying to pass the tax rates instead.

I also did a slight adjustment to the way you are doing the pay calculation.
