Hello
I am reading Agile Web Development with rails (third addition).
And I need some help with it.
I have reached chapter 9.3 (AJAX)
when I press on the add to cart button I get an error message.
a real ugly one.
eventually, I downloaded the PDF version and copied the content of the
files but it did not help.
I have looked but could not find the problem.
Please give me a hand.
the files of this application are at:
Download link: http://rapidshare.com/files/389266124/chapter-9.tar.gz
http://localhost:3000/store
I think that the error is written in javascript
and this is it:
---------------------------------------------------------------------
try {
Element.update("cart", "\n\n<div
class=\"cart-title\">Your
Cart</div>\n<table>\n \n\n\n<!-- START_HIGHLIGHT -->\n\n
<tr
id=\"current_item\"> \n\n<!-- #END_HIGHLIGHT
-->\n\n\n\n\n<tr>\n
<td>7×</td>\n <td>Pragmatic Project
Automation</td>\n <td
class=\"item-price\">$209.65</td>\n</tr>\n\n\n <tr
class=\"total-line\">\n <td
colspan=\"2\">Total</td>\n <td
class=\"total-cell\">$209.65</td>\n
</tr>\n\n</table>\n\n<form
method=\"post\" action=\"/store/empty_cart\"
class=\"button-to\"><div><input type=\"submit\"
value=\"Empty cart\"
/><input name=\"authenticity_token\" type=\"hidden\"
value=\"6ZdrTVjPgu0Lls4YyuTXbg1an5X/KKNZJKgDfruU6Qo=\"
/></div></form>\n");
$("current_item").visualEffect("highlight",
{"endcolor":"#114411","startcolor":"#88ff88"});
} catch (e) { alert(''RJS error:\n\n'' + e.toString());
alert(''Element.update(\"cart\", \"\\n\\n<div
class=\\\"cart-title\\\">Your Cart</div>\\n<table>\\n
\\n\\n\\n<!--

throw e }
