* 延迟指定时间后执行函数 */ Function.prototype.delay =function(timeout) { timeout = timeout || 0; varThis =this; //注意 arguments 不是数组 // arguments[0] 就是 timeout,后面的才是真正要传入的参数 varargs = Array.prototype.slice.call(arguments, 1); returnwindow.setTimeout(function() {...
functiondelay(callback,duration){setTimeout(callback,duration);} 1. 2. 3. 这里使用了setTimeout函数来实现延时操作,callback是一个回调函数,duration是延时的时间(以毫秒为单位)。 步骤2: 设置定时器 接下来,我们需要在延时后执行该函数。为此,我们使用setTimeout函数来创建一个定时器,以在指定的延时后调用...

In the above exercise JavaScript function "invokeAfterDelay()" takes a callback and invokes it after a delay of 2 second (2000 milliseconds) using the "setTimeout()" function. In the above function, the "display_message()" function will be invoked after a delay of 2 seconds. ...
