Question

I am using the following code in my Servlet to set the Attribute confirmMsg :

req.setAttribute("confirmMsg", "Update Values");

This I’m forwarding to the JSP

RequestDispatcher rd = req.getRequestDispatcher("displayDetails.jsp");
rd.forward(req, resp);

In my JSP, I need to display the message when the page loads.

<body onload = "showConfirmMsg();">

// .....

</body>

What should I do in the following function, so as to show the message onload itself?

function showConfirmMsg() {

// Code to show the alert box onload

}

Using jQuery, you can do something like:

<script>
$(function() {
    var msg = "${confirmMsg}";
    // do something with your message :)
});
</script>

<body onload=""> isn’t very clean 🙂
