Dear Wrox
I have been reading your book, Instant Javascript, unfortunatly, while
trying to create a shopping cart, and when trying to view the items int he
cart, i get the following error
Object doesn't support this action. On line 22, character 1
<HTML>
<BODY>
I currently have ordered:<BR><SCRIPT>
var i;
var linetotal = 0, subtotal = 0;
for ( i in top.cart)
{
document.write(' Item: '+top.cart[i].name);
document.write(', '+top.cart[i].quantity+' at '+top.cart[i].price);
linetotal = top.cart[i].quantity * top.cart[i].price;
document.write(' each makes: '+linetotal +'<BR>');
subtotal += linetotal;
}
document.write('<BR>Total due is: '+subtotal+'<BR>');
</SCRIPT>
<FORM METHOD="Post">
<SCRIPT>
var Item;
for (i in top.cart)
{
item = '<INPUT TYPE="hidden" NAME="'+i+'"
VALUE="'+top.cart[i].quantity+'">'; //LINE 22
document.write(item);
}
</SCRIPT>
<BR>
Credit Card Details
<INPUT TYPE="text" NAME="card_number">
<INPUT TYPE="submit" VALUE="BUY IT">
</FORM>
</BODY>
</HTML>
The page has been created for test purposes for now, but am planning on
implimenting it in an upcomming site. Please can you tell me why this is
happening.
I also get another problem in a different area. While trying to redirect a
page, where the browser is Netscape, the page will not redirect, I have
copied exactly what I found in the Instant HTML book on page 278, however
I am able to redirect with IE, but not with Netscape 4.72. I have tried
using the document.write('<META NAME="Refresh"
CONTENT=0;URL=netscape.html"> However neither location.href, nor
document.write work.
If you could contact me regarding these, I would be extremly grateful. I
must also give great thanks to wrox press. I currently own, Instant HTML,
Instant Javascript, and VBscript Programmers Reference I bought today. All
of which I have found to be very useful, and very detailed, which have
helped me immensly, and I will continue to buy your books, as I find them
to be the most useful of them all.
Many Thanks
Richard Poole
