Question

Let’s say I’m on the standard iPhone 4.

My menu bar is 2000px in width. When the user touches and holds on the menu div, he can move his finger left/right, and the menu bar will move. This allows the user to browse all of the menu’s items using his finger. (Scrolling left/right)

How can I make that in javascript/jquery?

It’s like the Google Images webview (go there on your phone). You’re able to swipe left and right to navigate each image.

Except…I want it to be a menu bar, with no “snapping”.

Answer 1

Here’s a very very basic example. It should get you moving in the right direction though.

$('body').bind({
    'touchmove': function(e){

        $('.menu_bar').css({
            'left': e.originalEvent.touches[0].pageX
        });

    }
});

To get where you’re headed you’ll need to also store the touchstart coordinates, the .menu_bar start position and then use a bit of math to move the bar relative to it’s position rather than just snapping to the finger position each time like the example above will do.

Hope that helps 🙂
