ExampleTop
Add handlers to be called when the Deferred
object is resolved or rejected.
In the example below when we press the left button the first time we create a Deferred
object and use some deferred object methods on it. We then resolve the
Deferred
object and hence deferred.always( alwaysCallbacks )
gets called with the message passed from the resolve.
When we press the right button the first time, we create a Deferred
object and use some deferred object methods on it. We then reject the
Deferred
object and hence deferred.always( alwaysCallbacks )
gets called with the message passed from the reject.
$(function(){
$('#btn1').one('click', function(){
var ourDeferred = $.Deferred();
ourDeferred.always( aFunc );
ourDeferred.progress( [aFunc, bFunc] );
ourDeferred.notify( 'The aFunc function was fired from our deferred. <br>', '#div1');
ourDeferred.resolve( 'Our deferred was resolved. <br>', '#div1' );
});
$('#btn4').one('click', function(){
var ourDeferred = $.Deferred();
ourDeferred.always( aFunc );
ourDeferred.progress( aFunc );
ourDeferred.notify( 'The aFunc function was fired from our deferred. <br>', '#div1' );
ourDeferred.reject( 'Our deferred was rejected. <br>', '#div1' );
});
function aFunc( value, div ){
$(div).append( value);
}
function bFunc( value, div ){
