<option value="${u.szj}" onclick="document.getElementById('transit_Distance').value=${{u.transit_Distance}">${u.szj_Name}</option>

<html:select property="szj"  style=""
           onchange="document.getElementById('transit_Distance').value=document.getElementById('sss_'+this.value).value">
          <html:option value="" > 未选择 </html:option>
          <c:forEach items="${requestScope.szj_list}" var="u">
