callbacks.fireWith( context, [arguments] ) ExampleTop

Invoke the callback list with the specified context and arguments.

In the example below when we press the button the first time we add the aFunc(value, div) and bFunc(value, div) functions to our callbacks list and fire them off with a context and array of arguments.

$(function(){
  $('#btn14').one('click', function(){
    var ourCallbacks = $.Callbacks();
    ourCallbacks.add( aFunc );
    ourCallbacks.add( bFunc );
    ourCallbacks.fireWith( window, ['Callbacks list called from the callbacks.fireWith()
                                     method. <br>','#div14']);
  });
  function aFunc( value, div ){
    $(div).append( value);
  }
  function bFunc( value, div ){
    aFunc('Passing bFunc function value to aFunc. <br>', div);
  }
});
