callbacks.locked()

V1.7概述

确定是否已被锁定的回调列表。

示例

描述:

用 callbacks.locked() 确定是否已被锁定的回调列表。:

jQuery 代码:
// a sample logging function to be added to a callbacks list var foo = function( value ){ console.log( 'foo:' + value); } var callbacks = $.Callbacks(); // add the logging function to the callback list callbacks.add( foo ); // fire the items on the list, passing an argument callbacks.fire( 'hello' ); // outputs 'foo: hello' // lock the callbacks list callbacks.lock(); // test the lock-state of the list console.log ( callbacks.locked() ); //true
