Display a javascript function as plaintext

Question

I have a javascript object with a defined function

var obj = {
    addOne : function( arg1 ) { return arg1++; }
};

At an onclick event, I want to display the function as plaintext. That is to say I want to somehow get the plaintext string 'function( arg1 ) { return arg1++; }' from obj so that I can display this string in a div block.

How do?

(To be clear, I am fine with printing out the string in an html element, but unclear on how to get the desired string in the first place)

In fact, that may not even be necessary because toString() is automatically called when you set a HTMLElement's textContent.

I very much enjoy when a solution turns out this simple.

@Bart - Yup, toString() is called when you try to reference a function in some place where a string is expected, but there's no harm in explicitly calling it here.
