Hi
I have a form with the input fields:
ProductName
Quantity
and output fields:
ProductPrice
TotalUSD
Here's what I want it to do:
a) After either the ProductName or Quantity fields are updated by the user,
I want the resulting calculation to be displayed for the Product Price and
the TotalUSD. The ProductName is a drop-down with the product name as the
description and the value the dollar amount of each product.
b) I want the output fields to be displayed as $ format.
c) I want it so that the output fields can't be manually overwritten by the
user and later the form will be posted to a database.
I began with the following but are not familiar with the syntax of
JavaScript and got syntax errors. I also need the syntax for the AfterUpdate
event for the two input fields. Can you help?
I think I'll name the form "Form1".
<SCRIPT LANGUAGE="JavaS cript">
Function CalculateTotal( form) {
form.ProductPri ce.value=(form. ProductName.val ue);
form.TotalUSD.v alue= (form.ProductNa me.value * form.Quantity.v alue)
}
</SCRIPT> 5 4694

There is no "AfterUpdat e" event. You want the onChange event.
onchange="Calcu lateTotal(this. form)"
I think I'll name the form "Form1".
<SCRIPT LANGUAGE="JavaS cript">
<script type="text"/javascript">
Function CalculateTotal( form) {
There is your syntax error, its function, not Function. Case Matters.
form.ProductPri ce.value=(form. ProductName.val ue); form.TotalUSD.v alue= (form.ProductNa me.value * form.Quantity.v alue)
Append the $ before setting the value, or better, as you set it.
"$" + (form.ProductNa me.value * form.Quantity.v alue)
} </SCRIPT>

Thanks. Regarding the currency, what if the multiplication causes greater
(or less) than 2 decimal places?

That is a copy/paste. See the double script tags? Its throwing a syntax
error and then stops. Get rid of the extra script tag, and then validate
your HTML: www.w3c.org http://diveintomark.org/archives/200..._wont_help_you
While looking through that code, I noticed you are using onblur to
validate your fields. That unnecessary. Use the onChange, or the
onSubmit event handlers.
<input type="text" size="8" name="Quantity" class="textbx" tabindex="5"
onblur="check1( this.form1)" onchange="Calcu lateTotal(this. form)"
value="1">
onChange="check 1(this.form);Ca lculateTotal(th is.form)"

If I had 2 tables, one that displayed ClaimNo, PartNo, and Quantity, and

add the associated quantity to table 2 from table 1, and if it is not found
to add it, with its associated quantity to table 2.
This should be simple.....its just a running total/tally....

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
