callbacks.has(callback)
概述
确定是否提供的回调列表
参数
callbackV1.7
用来搜索的回调。
示例
描述:
用 callbacks.has() 检查是否回调列表中包含一个特定的回调:
jQuery 代码:
// a sample logging function to be added to a callbacks list
var foo = function( value1, value2 ){
console.log( 'Received:' + value1 + ',' + value2 );
}
// a second function which will not be added to the list
var bar = function( value1, value2 ){
console.log( 'foobar');
}
var callbacks = $.Callbacks();
// add the log method to the callbacks list
callbacks.add( foo );
// determine which callbacks are in the list
console.log( callbacks.has( foo ) ); // true
console.log( callbacks.has( bar ) ); // false
