title: JavaScript on JSP with Spring form:select
body: <p>I have a jsp:</p>
  
  <pre><code>&lt;form:select path="operation" onchange="myFunc(${oper.id})"&gt;
    &lt;c:forEach items="${operList}" var="oper"&gt;
      &lt;form:option label = "${oper.name}" value="${oper.id}|${oper.name}"/&gt;...
  </code></pre>
  
  <p>And I have a js function <code>myFunc(id) { alert(id); }</code>
  Then I change select value I see alert: undefined. <br/>
  Wat's wrong?</p>
