Javascript get the value of all dropdowns
<p>I have a table which has multiple dropdowns, inside each row</p>

<pre><code>&lt;table style="width:100%"&gt;
  &lt;tr class= 'products'&gt;
    &lt;td&gt;Gold&lt;/td&gt;
    &lt;td&gt;
    &lt;select onchange='get_all_products()'&gt;
  &lt;option value="25"&gt;Gold 1&lt;/option&gt;
  &lt;option value="27"&gt;Gold 2&lt;/option&gt;
&lt;/select&gt;
    &lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr class= 'products'&gt;
    &lt;td&gt;Silver&lt;/td&gt;
    &lt;td&gt;
    &lt;select onchange='get_all_products()'&gt;
  &lt;option value="50"&gt;SILVER 1&lt;/option&gt;
  &lt;option value="476"&gt;SILVER 2&lt;/option&gt;
&lt;/select&gt;
&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr class= 'products'&gt;
    &lt;td&gt;Bronz&lt;/td&gt;
    &lt;td&gt;
    &lt;select onchange='get_all_products()'&gt;
  &lt;option value="71"&gt;BRONZ 1&lt;/option&gt;
  &lt;option value="89"&gt;BRONZ 2&lt;/option&gt;
&lt;/select&gt;
&lt;/td&gt;
  &lt;/tr&gt;
&lt;/table&gt;
</code></pre>

<p>on the <code>onchange</code> of each dropdown I want to get the value of all the dropdowns that are inside the class "products"  <code>&lt;tr class="products"&gt;</code></p>
