Alert data returned by Ajax

[S Rajagopal]

Hi All,

I have button in my Jsp page which triggers an Ajax call.The Ajax call directs the call to contoller which performs the action and returns the result (i.e success or failure )to a jsp page .
The data from this jsp page gets inserted into the <div> tag of the orginal Jsp page.
Is it possible to use an alert to notify the data retuned by ajax call?
Thanks in advance.

Clarification: no you don't. You have a button in your HTML page. JSP only exists on the server. Once the response is sent to the browser, it's just an HTML page like any other.

You can do whatever you want in the callback, including issuing an alert. (But why? Alerts are awful.)

You can do whatever you want after you get the response here is a sample to show you

This is the code for JS
$("#jspFieldId").blur( function() { $inputValue = document.getElementById("jspFieldId").value; $.post("./ajaxValidator", { inputVal : $inputValue, }, function(data) { alert(data) }); });
and this is what you should do in your ajax action

PrintWriter out = response.getWriter();
			out.println("This is your validation message");
			out.flush();
			out.close();

You did not mention that this assumes the use of jQuery, which is recommended for doing things like Ajax.
