关键语句jsp页面中加入后输出调用js方法：
 
<script language=\"javascript\">
<% //表单回写
  if(request.getAttribute(RuleExamineConstants.REQUEST_WRITE_BACK_FORM_VALUES) != null) { //如果request中取出的表单回写bean不为空
    out.print(RmVoHelper.writeBackMapToForm((java.util.Map)request.getAttribute(RuleExamineConstants.REQUEST_WRITE_BACK_FORM_VALUES))); //输出表单回写方法的脚本
  }
 Map mapt = (java.util.Map)request.getAttribute(RuleExamineConstants.REQUEST_WRITE_BACK_FORM_VALUES);
 System.out.print(\"infois:\"+mapt.entrySet());
 out.print(\"alert(1);\");
%>
</script>
 
//上面语句实际上注入的js格式内容如：
var mForm = new Object();
 var indexArray = new Array();

  for(var i=0; i<indexArray.length; i++) {
   writeBackValue(indexArray[i]);
  }
 }
