I am having a very hard time with this code. I have been working on it for days and cannot seem to figure it out. Please help!!
Here are the specific I need for the code:
Many companies normally
charge a shipping and handling
charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling
charge of $1.50 for any purchase that is less than or equal to $25.00. For any orders over $25.00, add 10% to the total purchase price for shipping and handling, but do not include the $1.50 minimum shipping and handling
charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling
charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box.
Here is the code I have:
<!DOCTYPE>
<head>
<title>Calculate Shipping</title>
<script type="text/javascript">
function parseInt() {
var salesPrice = document.salesForm.Price.value;
var minCharge = salesPrice + 1.50;
var shipping = salesPrice * 10/100;
if (salesPrice <= 25)
window.alert('Your sales total including shipping is $' + minCharge);
else
window.alert('Your sales total including shipping is $' + salesPrice + shipping);
}
</script>
</head>
<body>
<form name="salesForm">
<div >
<p>Enter Your Purchase Price</p>
<input type="text" name="Price" /><br /><br />
<input type="button" name="Calculate" value="Calculate Shipping"
onclick="parseInt ()" />
</div>
</form>
</body>
</html>
Everything works except for the math in the alert box. It will show an incorrect total...
