How to manage a redirect request after a jQuery Ajax call?

0 votes

Using $.post() to call a servlet using Ajax and then using the resulting HTML fragment to replace a div element in the user's current page. However, if the session times out, the server sends a redirect directive to send the user to the login page. In this case, jQuery is replacing the div element with the contents of the login page, forcing the user's eyes to witness a rare scene indeed.

Hii kartik,

You can resolved this issue like this:

Add a middleware to process response, if it is a redirect for an ajax request, change the response to a normal response with the redirect url.

class AjaxRedirect(object):
  def process_response(self, request, response):
    if request.is_ajax():
      if type(response) == HttpResponseRedirect:
        r = HttpResponse(json.dumps({'redirect': response['Location']}))
        return r
    return response

Then in ajaxComplete, if the response contains redirect, it must be a redirect, so change the browser's location.

$('body').ajaxComplete(function (e, xhr, settings) {
   if (xhr.status == 200) {
       var redirect = null;
       try {
           redirect = $.parseJSON(xhr.responseText).redirect;
           if (redirect) {
               window.location.href = redirect.replace(/\?.*$/, "?next=" + window.location.pathname);
           }
       } catch (e) {
           return;
       }
   }
}

Hope this works!!

Thank You!!
