javascript - 我可以获取存储在对象中的函数的字符串化代码吗？(Can I get the stringified code of a function stored in an object?)

Question

If I store a javascript function inside an Object like this :

(如果我将javascript函数存储在这样的Object中：)

 jsObject = { TestFuntion1 : function(){ var x = 1; return x; }, TestFunction2 : function(){ console.log("Hello World"); } } 

Can I get the content of these function as a string ?

(我能否以字符串形式获取这些函数的内容？)

var x = 1; return x;    /*OR*/   console.log("Hello World");

I tried playing with the 'prototype', but nothing seems to return me the content of it.

(我曾尝试过使用“原型”，但似乎没有任何东西可以退还给我。)

Thank you for your help !

(谢谢您的帮助 ！)

This can be done with the toString() function followed by a little parsing to make it look as desired:

(这可以通过toString（）函数完成，然后进行一些解析以使其看起来像期望的那样：)

//convert to string
var str = jsObject.TestFuntion1.toString();

//parse to make it look like you want:
str = str.substring(0, str.length - 1).replace("function(){", "").trim().replace(/
/g, "").replace(/;s+/, "; ");

//check the result
console.log(str);//"var x = 1; return x;"
