从列表中删除所有的回调.
使用 callbacks.empty() 清空回调列表:
// a sample logging function to be added to a callbacks list
var foo = function( value1, value2 ){
console.log( 'foo:' + value1 + ',' + value2 );
}
// another function to also be added to the list
var bar = function( value1, value2 ){
console.log( 'bar:' + value1 + ',' + value2 );
}
var callbacks = $.Callbacks();
// add the two functions
callbacks.add( foo );
callbacks.add( bar );
// empty the callbacks list
callbacks.empty();
// check to ensure all callbacks have been removed
console.log( callbacks.has( foo ) ); // false
console.log( callbacks.has( bar ) ); // false
