Rails Trying to submit a form onchange of dropdown <p>I have my Ajax working, builtin Rails javascript, with the submit button. However, I would like it to submit when I change the value of the dropdown box and eliminate the button. In my research I found what looks like the correct solution but I get no request to the server. Here is my dropdown form code, note it still has the submit button that worked before I added :onchange:</p> <pre><code> &lt;% form_tag('switch_car', :method =&gt; :put, :remote =&gt; true) do %&gt; &lt;div class="field"&gt; &lt;label&gt;Car Name:&lt;/label&gt; &lt;%= select_tag(:id, options_from_collection_for_select(active_cars, "id", "name"), :onchange =&gt; ("$('switch_car').submit()"))%&gt;&lt;%= submit_tag "Switch Car" %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>Here is the HTML generated:</p> <pre><code>&lt;form accept-charset="UTF-8" action="switch_car" data-remote="true" method="post"&gt;&lt;div style="margin:0;padding:0;display:inline"&gt;&lt;input name="utf8" type="hidden" value="&amp;#x2713;" /&gt;&lt;input name="_method" type="hidden" value="put" /&gt;&lt;input name="authenticity_token" type="hidden" value="PEbdqAoiik37lcoP4+v+dakpYxdpMkSm7Ub8eZpdF9I=" /&gt;&lt;/div&gt;&lt;div class="field"&gt; &lt;label&gt;Car Name:&lt;/label&gt; &lt;select id="id" name="id" onchange="$('switch_car').submit()"&gt;&lt;option value="9"&gt;Truck&lt;/option&gt; &lt;option value="10"&gt;Car&lt;/option&gt;&lt;/select&gt;&lt;input name="commit" type="submit" value="Switch Car" /&gt; &lt;/div&gt; </code></pre> <p>Thanks in advance for any help. </p>
