Question

I translate some Mootools script to jQuery, and I have function:

play:function( delay, direction, wait )
{       
    this.isRun = this[direction].periodical(delay,this,true);
}

Header of one from functions which are substituted by this[direction] is:

next:function(manual , item)

Only I found is: use setInterval, but how I can pass parameters to the call?
Things such as:

setInterval(direction + '(' + delay + ', this)')

Very hard for debugging and not beautiful…
Is here more beautiful way, maybe using other methods?

Looks like you need an anonymous function. Try something like this:

play:function( delay, direction, wait )
{       
    this.isRun = setInterval(function(){
            this[direction].call(this, true)
        },
        delay
    );
}
