Question

I’m trying to get a ‘loading’ div for my ajaxified website.
using JSF 2.0’s f:ajax tag for adding ajax to the website and ‘trying’ to make the loadin div show using jQuery $(document).ajaxStart function.

The jQuery code part looks like this:

$(document).ajaxStart(function(){
    console.log("ajax start");
  $('#ajaxBusy').show(); 
}).ajaxStop(function(){
    console.log("ajax end");
  $('#ajaxBusy').hide();
});

The log functions are never called.
Any Idea why? Do JSF ajax and javascript ajax not work together?

Thanks!

You should use jsf.ajax.addOnEvent(callback) to display a loading div. Maybe addOnError too.

See the documentation

jsf.ajax.addOnEvent(statusUpdate);
...
var statusUpdate = function statusUpdate(data) {
...
}

You will need to work with data.status

• begin: before the request is sent
• complete: request recieved
• success: request succesfully processed (without errors)
