callbacks.add( callbacks ) ExampleTop
Add callback(s) to a callback list.
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.
$(function(){
$('#btn6').one('click', function(){
var ourCallbacks = $.Callbacks();
ourCallbacks.add( aFunc );
ourCallbacks.fire( 'The aFunc function was fired from our callbacks. <br>', '#div6');
ourCallbacks.add( bFunc );
ourCallbacks.fire( 'The bFunc function was fired from our callbacks. <br>', '#div6');
});
function aFunc( value, div ){
$(div).append( value);
}
function bFunc( value, div ){
aFunc('Passing bFunc function value to aFunc. <br>', div);
}
});
