關(guān)鍵語句jsp頁面中加入后輸出調(diào)用js方法：
 
<script language="javascript">
<% //表單回寫
  if(request.getAttribute(RuleExamineConstants.REQUEST_WRITE_BACK_FORM_VALUES) != null) { //如果request中取出的表單回寫bean不為空
    out.print(RmVoHelper.writeBackMapToForm((java.util.Map)request.getAttribute(RuleExamineConstants.REQUEST_WRITE_BACK_FORM_VALUES))); //輸出表單回寫方法的腳本
  }
 Map mapt = (java.util.Map)request.getAttribute(RuleExamineConstants.REQUEST_WRITE_BACK_FORM_VALUES);
 System.out.print("infois:"+mapt.entrySet());
 out.print("alert(1);");
%>
</script>
 
//上面語句實際上注入的js格式內(nèi)容如：
