I would like to create a simple price calculator, basically
QUANTITY x PRICE + a flat rate SHIPPING/HANDLING = TOTAL
But then I would also like to be able to show/calculate a discount if they purchase 25 or more of one item. Can someone help me write this?
Thanks! |

Here is something I got from the 24-Hour HTML Cafe:

<script language="JavaScript">
<!--
function CalculateTotals(){
f=document.orderform;
f.total1.value=parseInt(f.qty1.value)*50;
f.total2.value=parseInt(f.qty2.value)*295;
f.total3.value=parseInt(f.qty3.value)*395;
f.total4.value=parseInt(f.qty4.value)*750;
f.grandtotal.value=parseInt(f.total1.value)
+parseInt(f.total2.value)
+parseInt(f.total3.value)
+parseInt(f.total4.value)
+parseInt(f.sh.value);}
//-->
</script></head>
<body>
<form name="orderform" method="post" action="formprocessor">
<table border="3"><tr>
<th>Qty</th><th>Part #</th><th>Description</th>
<th>Price</th><th>Total</th></tr>
<tr><td>
<input name="qty1" size="3" OnBlur="CalculateTotals()" /></td>
<td>25791</td><td>Chromated Flywheel Knob</td>
<td align="right">$50</td>
<td><input name="total1" size="7"
OnFocus="document.orderform.qty2.select();
document.orderform.qty2.focus();" /></td></tr>

<td align="right">$750</td>

OnFocus="document.orderform.qty1.select();
document.orderform.qty1.focus();" /></td></tr>
<tr><td></td><td></td><td></td>
<td align="right">Shipping and handling:</td><td> $5</td></tr>
<tr><td></td><td></td><td></td>
<td align="right"><b>GRAND TOTAL:</b></td>
<td><input name="grandtotal" size="7"
OnFocus="document.orderform.qty1.select();
document.orderform.qty1.focus();" /></td></tr>
</table>
<input type="hidden" value="5" name="sh" />
<br /><input type="submit" value="Make Purchase" />
</form>
<script language="JavaScript">
<!--
f=document.orderform;
f.qty1.value=0; f.qty2.value=0;
f.qty3.value=0; f.qty4.value=0;
f.total1.value=0; f.total2.value=0;
f.total3.value=0; f.total4.value=0;
f.sh.value=5;
f.grandtotal.value=5;
//-->
</script>
</body></html> |
You can easily change this for your own puposes if you know a little JavaScript and HTML. |

Do you know how I would go about creating something that will be suitable for this problem? Thank you any help would be great.
Problem:
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 JavasScript 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 order 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 the percentage is price * percent / 100. For example, the formula for calculating 10% of the $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. |
