If the submission is successful, I need to include Javascript code in the confirmation message to track the conversion. </p> <p>For testing I have used just an <code>alert(&quot;Conversion happened&quot;)</code> box and noticed that it is shown twice for Ajax-enabled forms. I have not yet tested with the actual conversion code, but my guess is that 2 conversions will occur instead of one because of this behaviour.</p> <p>After several hours of debugging I have found out that this happens because the JS code is executed once inside the hidden &lt;iframe&gt; used as the target for Ajax-enabled forms and once when the confirmation message is added to the page (in GFFormDisplay::get_form() method - line 607 from "form_display.php", GF 1.7.5):</p> <pre><code>&quot;jQuery(&#39;#gform_wrapper_{$form_id}&#39;).replaceWith(&#39;&lt;&#39; + &#39;div id=\&#39;gforms_confirmation_message\&#39; class=\&#39;gform_confirmation_message_{$form_id}\&#39;&#39; + &#39;&gt;&#39; + confirmation_content + &#39;&lt;&#39; + &#39;/div&#39; + &#39;&gt;&#39;);&quot; .</code></pre> <p>The solution I came up with was to remove &lt;script&gt; / &lt;noscript&gt; tags from the confirmation message before it is inserted in the page - this way scripts are executed only once inside the hidden &lt;iframe&gt;. For backwards compatibility, I made this configurable using "gform_confirmation_scripts_once" filter. Please see the unified diff file here: </p> <p><a href="http://pastie.org/8040491" rel="nofollow">http://pastie.org/8040491</a></p> <p>Another possible issue is on line 604 from "form_display.php":<br /> <pre><code>&quot;confirmation_content = contents;&quot;.</code></pre> <p>where "contents" variable is set on line 585:<br /> <pre><code>&quot;var contents = jQuery(this).contents().find(&#39;*&#39;).html();&quot; .</code></pre> <p>This will insert the entire content of the hidden &lt;iframe&gt;, including the:<br /> <pre><code>&lt;head&gt;&lt;meta charset=&#39;UTF-8&#39; /&gt;&lt;/head&gt;</code></pre> <p>element inside the "#gforms_confirmation_message" &lt;div&gt;. In my opinion, only the &lt;iframe&gt; body content should be inserted in the page, so line 604 should be:<br /> <pre><code>&quot;confirmation_content = jQuery(this).contents().find(&#39;.GF_AJAX_POSTBACK&#39;).html();&quot;.</code></pre> <p>The diff file above includes all these changes. It would be nice if you could include them in the next GF version, if they seem correct to you. </p> <p>Kind regards,<br /> Eugen </p>
