我试图通过从JSP中的请求参数,在我的基于struts的项目中将字符串值传递给JavaScript函数.这是代码：

<%
String timeVal = "Not found";   
    if(request.getAttribute("myDate")!=null){       
        timeVal= (String)request.getAttribute("myDate");
    } 
%>

然后将其作为参数传递给函数

<html:submit property = "save" styleClass = "button_c" onclick = "return SubmitPage('update', <%=timeVal %>)">Save</html:submit>

JavaScript函数的位置

function SubmitPage(action, aa)
{   

alert("Date is  ...." + aa);

}

但是,当我尝试运行它时,它给了我一个错误

HTTP Status 400 - Request[/AMResourceLibraryListAction] does not contain handler parameter named ref

随着网页上的消息.

Request[/AMResourceLibraryListAction] does not contain handler parameter named ref

提前致谢.

编辑这是堆栈跟踪

[ERROR] DispatchAction - -Request[/AMResourceLibraryListAction] does not contain handler parameter named ref

解决方法:

这对我有用：

<html:submit property = "save" styleClass = "button_c" onclick = "return SubmitPage('<%=timeVal %>')">Save</html:submit>

(‘<％= timeVal％>‘)//单个报价之间
