想要将Java值传递到jsp中的javascript函数中 [英] Want to pass the java value into javascript function in jsp

问题描述

在基于Struts的项目中，我试图通过从JSP中的request参数获取字符串值到JavaScript函数.这是代码:

I am trying to pass a string value to a JavaScript function by taking from request parameter in JSP, in my struts based project. here is the code:

<%
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

and then pass it in function as parameter

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

其中的JavaScript函数是

Where the JavaScript function is

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

But when i try to run this it gives me an error

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

在网页上显示消息.

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

谢谢.

编辑这是堆栈跟踪

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

推荐答案

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

('<%=timeVal %>') // between single Quotation
