getting requestattributes in javascript

I want to retrieve the request scope attribute in javascript as follows. How can I achieve this?

function caseChanges(req) {
    var innervalue= "${dashboardTicketSummary}"
    alert("nand you are 1234");
    alert(innervalue);
}
Solution

  • Assumin the javascript is included inline on the jsp page -- you're on the right track, you just need to make sure the attribute is set (typically by your controller class) on the HttpServletRequest object, ie:

    @Override
protected void doGet(HttpServletRequest req, HttpServletResponse res)
{
  DashboardTicketSummary dts = ...; // code to obtain ticket summary here

  req.setAttribute("dashboardTicketSummary", dts);

  // code to dispatch to your jsp page here
}

    Of course there are many other more sophisticated way -- especially is you use popular MVC framework such as Spring
