传递给函数后确定变量的原始名称 [英] Determine original name of variable after its passed to a function

问题描述

我有一种感觉，这可能是不可能的，但我想确定一个已经传递给javascript中的函数的变量的原始变量名。我不知道如何更好地解释它，所以看看这个例子是否有意义。

I've got a feeling this might not be possible, but I would like to determine the original variable name of a variable which has been passed to a function in javascript. I don't know how to explain it any better than that, so see if this example makes sense.

function getVariableName(unknownVariable){
  return unknownVariable.originalName;
}

getVariableName(foo); //returns string "foo";
getVariableName(bar); //returns string "bar";

这是我正在研究的jquery插件，我希望能够显示传递给调试函数的变量的名称。

This is for a jquery plugin i'm working on, and i would like to be able to display the name of the variable which is passed to a "debug" function.

推荐答案

你是对的，这是非常不可能的以任何理智的方式，因为只有值传递给函数。

You're right, this is very much impossible in any sane way, since only the value gets passed into the function.
