iTouch effect is a bit buggy when used on desktop (has a fix) about smooth-div-scroll

[tkahn]

Interesting! I don't have a desktop computer with touch so feedback like this is very valuable. There is a fix to prevent selecting/highlighting of the elements in the scroller that I apply in the CSS for the elements inside the scrollable area:

    #makeMeScrollable div.scrollableArea *
    {
        position: relative;
        display: block;
        float: left;
        margin: 0;
        padding: 0;
        /* If you don't want the images in the scroller to be selectable, try the following
           block of code. It's just a nice feature that prevent the images from
           accidentally becoming selected/inverted when the user interacts with the scroller. */
        -webkit-user-select: none;
        -khtml-user-select: none;
        -moz-user-select: none;
        -o-user-select: none;
        user-select: none;
    }

If you remove the prevent dragstart fix and apply the CSS above, does it work or do you need both? It would be great if you could test this for me! Thanks in advance!

Hi /Thomas

First up the dragstart fix does work without the CSS - which I hadn't realised.

Without the dragstart fix the CSS works for some elements of my slides and not others. Each of my slides are made up of h2, h3 and img elements all contained inside a link element:

<a class="slide">
    <h2>...</h2>
    <h3>...</h3>
    <img />
</a>

Interestingly, if I click and drag the img the CSS fix works but if I click and drag the header elements FF thinks I want to move the whole link element off the page and this gets in the way of the iTouch effect.

I should point out at this point that my desktop is not a touch device, I'm reporting on the effect of using iTouch on my regular desktop browser (Firefox 15.0.1)

Be happy to do more testing. Thanks for the code. It's great!

Hi!

Hmm, this is a tricky one.
What happens if you change the CSS to:

#makeMeScrollable div.scrollableArea a
    {
        position: relative;
        display: block;
        float: left;
        margin: 0;
        padding: 0;
        /* If you don't want the images in the scroller to be selectable, try the following
           block of code. It's just a nice feature that prevent the images from
           accidentally becoming selected/inverted when the user interacts with the scroller. */
        -webkit-user-select: none;
        -khtml-user-select: none;
        -moz-user-select: none;
        -o-user-select: none;
        user-select: none;
    }

...i.e. changing the "*" to an "a" to more precisely match your setup?

Hi /Thomas

I've amended my CSS - good call, there was no need to use a wildcard.

This doesn't change anything drag/select-wise. There is still a confusion when I click the titles to drag them but the images behave well if I drag them instead.

The dragstart-prevent-default solution seems to be a goodun:

My code looks like this:

$(document).ready(function () {

    $("div#slides").smoothDivScroll({
        autoScrollingMode: "always", 
        autoScrollingDirection: "endlessLoopRight",
        hotSpotScrolling: false,
        touchScrolling: true,
        manualContinuousScrolling: true
    });

    // Prevents slides being selected.
    $('div#slides').bind('dragstart', function(e) { e.preventDefault(); });
});
