有没有办法从当前函数中获取当前函数？ [英] Is there a way to get the current function from within the current function?

问题描述

  var f1 = function（param1 ，param2）{
 
 //有没有办法获得'f1'
 //（当前函数）的对象？ 
 
}; 
  

正如您所看到的，我想从一个匿名函数中访问当前函数。 p>

这可能吗？

解决方案

是 - arguments.callee 是当前函数。

注意：ECMAScript 5中不推荐使用，并且可能导致尾部递归性能下降等等。然而，它在大多数主流浏览器中都能正常工作。

在你的情况下， f1 也可以工作。

Sorry for the really weird title, but here’s what I’m trying to do:

var f1 = function (param1, param2) {

    // Is there a way to get an object that is ‘f1’
    // (the current function)?

};

As you can see, I would like to access the current function from within an anonymous function.

Is this possible?

解决方案

Yes – arguments.callee is the current function.

NOTE: This is deprecated in ECMAScript 5, and may cause a performance hit for tail-call recursion and the like. However, it does work in most major browsers.

In your case, f1 will also work.
