[jQuery] Re: can someone translate this syntax ?

[Andy Matthews]

That's called ternary syntax:

(expression) ? True : false;

If the expression evaluates to true, then the true portion is run, else the
false portion is run. A real world example:

Var total = (myValue == 15) ? 15 * 3 : myValue / 2;

Not helpful, but that's how it's used.

As for the other portion, Javascript allows you to set multiples values at
once. Because the author is performing an assignment (animCss = blah), it
doesn't return anything so the value of running is set to false.

(function($) {
$.fn.jCarouselLite = function(o) {
    o = $.extend({
        btnPrev: null,
        btnNext: null,
        btnGo: null,
        mouseWheel: false,
        auto: null,

        speed: 200,
        easing: null,

        vertical: false,
        circular: true,
        visible: 3,
        start: 0,
        scroll: 1,

        beforeStart: null,
        afterEnd: null
    }, o || {});

    return this.each(function() {

        var running = false, animCss=o.vertical?"top":"left",
sizeCss=o.vertical?"height":"width";
        var div = $(this), ul = $("ul", div), tLi = $("li", ul), tl =
tLi.size(), v = o.visible;

    });
};

})(jQuery);




I don't understand this part

 var running = false, animCss=o.vertical?"top":"left",
sizeCss=o.vertical?"height":"width";
 var div = $(this), ul = $("ul", div), tLi = $("li", ul), tl = tLi.size (),
v = o.visible;

Can you fully translate it for me please.
