title: How to call Spring MVC Portlet Controller method by selecting value from a dropdown in jsp
body: <p>I want to call controller method after user selects a value from the dropdown in JSP. But not getting how to move forward.
  My jsp looks like this:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  function repopulate(){
  alert(document.getElementById('test').value);
  }&lt;/script&gt;
  
  &lt;form:select id="test" path="billingOverview.msisdnNumber"  onChange="repopulate()"&gt;
                      &lt;form:option value="" label="All" /&gt;
                      &lt;c:forEach var = "billingOver" items = "${billingOverview.prepaidBillingInfo}"&gt;
                      &lt;form:option value="${billingOver.msisdn}" &gt;&lt;c:out value="${billingOver.msisdn}"/&gt;&lt;/form:option&gt;
                      &lt;/c:forEach&gt;
  &lt;/form:select&gt;
  </code></pre>
