deferred.state() ExamplesTop

Determine the current state of a Deferred object.

In the example below when we press the button the first time we create a Deferred object . We then notify and resolve the Deferred object and process any progressCallbacks and doneCallbacks.

$(function(){
  $('#btn16').one('click', function(){
    var ourDeferred = $.Deferred();
    ourDeferred.always( eFunc );
    $('#div1').append( 'Current state of ourDeferred: ' + ourDeferred.state() + ' <br>');
    ourDeferred.resolve( 'Our deferred was resolved. <br>', '#div1');
    $('#div1').append( 'Current state of ourDeferred: ' + ourDeferred.state() + ' <br>');
  });

  function eFunc( value, div ){
    $(div).append( 'In eFunc: ' + value);
  }
});
