那么,在python中如何实现回调函数呢,看代码: # 被调用的回调函数 def my_callback(input): print("function my_callback was called with %s input" % (input,)) # 调用函数 def caller(input, func): func(input) for i in range(5): caller(i, my_c
但是有些库函数(library function)却要求应用先传给它一个函数,好在合适的时候调用,以完成目标任务。这个被传入的、后又被调用的函数就称为回调函数(callback function)。 打个比方,有一家旅馆提供叫醒服务,但是要求旅客自己决定叫醒的方法。可以是打客房电话,也可以是派服务员去敲门,睡得死怕耽误事的,还可以要求...
也就是把回调函数传入库函数的动作，称为登记回调函数（to register a callback function）。
A“callback function” in Python is a user-defined function that is input as a parameter value to the main function. The callback function is called at a specific point in the main function. To call multiple callback functions into the main function, we create the list of callback functio...
System callback functions have fixed function names, such as sysCall_init or sysCall_beforeInstanceSwitch. Not all system callback functions are supported by all types of scripts, e.g. some can only run in an add-on (e.g. sysCall_addOnScriptSuspend)....

例如：def my_callback(input): print "function my_callback was called with %s input" % (input,)def caller(input, func): func(input)for i in range(5): caller(i, my_callback)执行结果是：function my_callback was called with 0 inputfunction my_callback was called...
A callback function is executed after the current effect is finished. Typical syntax:$(selector).hide(speed,callback); Examples The example below has a callback parameter that is a function that will be executed after the hide effect is completed: ...
