OOP with JavaScript

consider the following:

function dMenu(title)
{
    this.time = 0;
    this.items = null;
    this.header = null;
    this.title = title;
}

dMenu.prototype.startIt = function()
{
     this.time++;
     setTimeout( ??????, 1000 );
}

what should i type instead of question marks to increment "time" variable every 1 second?

Presumably it would have to call itself therefore it would be easier if it were not an anonymous function:

Code:

dMenu.prototype.startIt = incTime;

function incTime()
{
   this.time++;
   setTimeout( incTime, 1000 );
}

try arguments.callee to obtain a reference of the Function object beeing executed. This way your func can stay anonymous.

I thought this was "caller" and a property of the Function object? In which case you're no better off.
