jQuery: how do I append variables onto a form path?
<p>Lets say the URL in my form is </p>

<pre><code>action="/medias/new_from_disk?CKEditor=content_body&amp;CKEditorFuncNum=1&amp;langCode=en"
</code></pre>

<p>and the form has ID <code>myform</code>
how would I conjure a jQuery command to add to the action</p>

<pre><code>&amp;var=value
</code></pre>

<p>?</p>

<p>complete form:   </p>

<pre><code>&lt;form enctype="multipart/form-data"
       id="myform"
       method="POST" 
       action="/medias/new_from_disk?CKEditor=content_body&amp;amp;CKEditorFuncNum=1&amp;amp;langCode=en"&gt;
 &lt;/form&gt;
</code></pre>
