JQuery deferred.notifyWith() method
This deferred.notifyWith() method in JQuery is used to call the progressCallbacks on a Deferred object along with the provided context and args.
Syntax:
deferred.notifyWith(context[, args])
Parameters:
- context: This parameter is the context passed to the progressCallbacks as the ‘this’ object.
- args: This parameter is an optional array of arguments which are passed to the progressCallbacks.
Return Value: This method returns the deferred object.
There are two examples discussed below:
Example-1: In this example, We notify the Deferred object with two arguments and process any progressCallbacks before rejecting it.

var el_up = document.getElementById("GFG_UP");
el_up.innerHTML = "JQuery | deferred.notifyWith() method";
function Func(val, div){
$(div).append('From function "Func": ' + val);
}
function Geeks() {
var def = $.Deferred();
def.progress(Func);
def.notifyWith(
this, ['notifyWith() is called with arguments. < br />', '#GFG_DOWN']);
}
</ script >
</ body >

Output:
Example-2: In this example, We notify the Deferred object with only one arguments and process any progressCallbacks before resolving it.
