json - Javascript: stringify object (including members of type function)

Question

I'm looking for a solution to serialize (and unserialize) Javascript objects to a string across browsers, including members of the object that happen to be functions. A typical object will look like this:

{
   color: 'red',
   doSomething: function (arg) {
        alert('Do someting called with ' + arg);
   }
}

doSomething() will only contain local variables (no need to also serialize the calling context!).

JSON.stringify() will ignore the 'doSomething' member because it's a function. I known the toSource() method will do what I want but it's FF specific.

You can use JSON.stringify with a replacer like:

JSON.stringify({
   color: 'red',
   doSomething: function (arg) {
        alert('Do someting called with ' + arg);
   }
}, function(key, val) {
        return (typeof val === 'function') ? '' + val : val;
});
