Jquery toastr onHidden function

Question

I am using jquery toastr. So far everything is great. I can display and close toasts fine. I want to be able to identify each toast uniquely. And use that unique identifier in the onHidden function. Has anyone done this before? Is the better option to call a jquery on close event for the toastr class or div surrounding the closed toast?

    var mes = 'My name is Inigo Montoya.<input type="hidden" id="announcementId" value="1"/>' +
       '<input type="hidden" id="userId" value="'+ userid +'"/> ';

    var mes1 = 'Princess Bride<input type="hidden" id="announcementId2" value="2"/>'+
       '<input type="hidden" id="userId1" value="'+ userid +'"/> ';

    var mes2 = 'Man in Black<input type="hidden" id="announcementId2" value="3"/>'+
       '<input type="hidden" id="userId2" value="'+ userid +'"/> ';

   var mes3 = 'Inconcivable!<input type="hidden" id="announcementId3" value="4"/>'+
       '<input type="hidden" id="userId3" value="'+ userid +'"/> ';

toastr.options = {
  "closeButton": false,
  "debug": false,
  "positionClass": "toast-top-full-width",
  "showDuration": "300",
  "hideDuration": "1000",
  "timeOut": "0",
  "extendedTimeOut": "0",
  "showEasing": "swing",
  "hideEasing": "linear",
  "showMethod": "fadeIn",
  "hideMethod": "fadeOut"
};

toastr.options.onHidden = function(item) { 
//GET UNIQUE TOAST ID'S HERE
        var val = 1;//$this.find("#announcemntId").val();
        alert("CLOSED " + item); 
}

toastr.error(mes, "First Toast");
toastr.error(mes1, "Second Toast");
toastr.error(mes2, "Third Toast");
toastr.error(mes3, "Fourth Toast");

Answer 1

You can pass the third parmeter which is the options override

toastr.error('Some error', 'Error', { onHidden: function() {
         console.log('Error toast hidden.')
}});

or modify the global onHidden

var onHiddenToast = function () { 
        console.log("onHidden");
}
toastr.options.onHidden = onHiddenToast;

also you can get the toast simply by referencing it

var myToast = toastr.info("Some info");
//do what you want with myToast
