How through select to add request parameters?

Question

I have such a question. Is it possible to send a parameter with <select> in any way? I tried to do it on onchange but that does not work

I am tried this way:

<select name="locale" onchange="this.value">
    <option value="${requestScope['javax.servlet.forward.request_uri']}?lang=en_US" ${pageContext.request.locale eq 'en_US' ? 'selected' : ''}><fmt:message key="english"/></option>
    <option value="${requestScope['javax.servlet.forward.request_uri']}?lang=ru" ${pageContext.request.locale eq 'ru' ? 'selected' : ''}><fmt:message key="russian"/></option>
</select>
<a href="${requestScope['javax.servlet.forward.request_uri']}?lang=en_US"><fmt:message key="english"/></a>
<a href="${requestScope['javax.servlet.forward.request_uri']}?lang=ru"><fmt:message key="russian"/></a>

With links, everything works fine, but how do I send the parameter via <select>

Please try the below code to select the current value in the dropdown and then take actions upon it.

<select id="locale">
    <option value="${requestScope['javax.servlet.forward.request_uri']}?lang=en_US" ${pageContext.request.locale eq 'en_US' ? 'selected' : ''}><fmt:message key="english"/></option>
    <option value="${requestScope['javax.servlet.forward.request_uri']}?lang=ru" ${pageContext.request.locale eq 'ru' ? 'selected' : ''}><fmt:message key="russian"/></option>
    </select>

    <script type="text/javascript"> 
    $(document).ready(function () { 
     $('#locale').change(function(){ 
      var localeVal = $(this).val();//gets the current selected dropdown value 
     });
    });
    </script>
