As it stands, using the code I posted above, clicking on the image with JS off does nothing.</p> <p>Why is that? It&#8217;s calling the same action, so the request.xhr? conditional should work the same as clicking the Add to Cart button, right?</p> <p>I tried refactoring the link as follows, which I got to work but the display got fouled up and my initial attempts to fix the <span class="caps">CSS</span> didn&#8217;t work (e.g., display: inline;, wrapping it in a new div class, etc.).<br /><pre><code> &lt;% form_remote_tag :url =&gt; {:action =&gt; :add_to_cart, :id =&gt; product} do %&gt; &lt;%= image_submit_tag(product.image_url) %&gt; &lt;% end %&gt; </pre></code><br />Is this the correct approach (and thus I just need to fix my <span class="caps">CSS</span>), or is there a better way?</p> Fri, 09 May 2008 21:08:11 -0000 forums.pragprog.com:66:421:2772 Scott Gardner http://forums.pragprog.com/forums/66/topics/421 <p>The end of lesson assignments previously had us make the image a link to add_to_cart. Once you switch over to using an Ajax cart, your link will no longer work. Here&#8217;s my code to update that link:</p> <p>depot/app/views/store/index.html.erb<br /><pre><code> &lt;%= link_to_remote image_tag(product.image_url), :url =&gt; {:action =&gt; 'add_to_cart', :id =&gt; product} %&gt; </pre></code></p> Fri, 09 May 2008 17:05:01 -0000 forums.pragprog.com:66:421:2770 Scott Gardner http://forums.pragprog.com/forums/66/topics/421
