用纯javascript写的异步调用js文件xmlcommon.js一

在页面调用方式：

1）<script language="javascript" src="<%=request.getContextPath()%>/js/xmlcommon.js"></script>

2）<select id="departmentCode" name="departmentCode" onchange="departmentCodeChange(this.value);">
                         <jsp:include page="../common/tag_select_department.jsp">
                             <jsp:param name="hasOptioanal" value="1" />
                         </jsp:include>
                     </select>

3）<script languge="javascript">
function departmentCodeChange(departmentCode){
 url = "calib0GetDecisionRule.do?departmentCode="+departmentCode;
 handlerRequestURLXML( url, setFields );
}
function setFields(request) {
 if(document.getElementById("calibRuleId").length > 0){
   document.getElementById("calibRuleId").length = 0;
  }
 setElementList(request);
}

</script>
