Hammer.js: options to prevent native link and image dragging?

[bitinn]

On desktop browser, when child element of Hammer instance contains link or image, mousedown + dragging will result in native drag and drop (and affect pan/swipe interaction). I am not sure this has been covered in hammer.js, or should we disable drag and drop for each images/links manually.

So far I know only one way to disable native drag and drop consistently, set attribute draggable="false" on each link and image (can't be done on container). This works fine, but I am not sure it's recommended way to do such thing, are there better alternatives?

Hammer doesnt handle this for you. Setting the draggable attribute is fine! Or you could let the ondrag event return false. Also, -webkit-user-drag: none in css will help, but only on webkit :-)

css:

img, a{ -webkit-user-select: none; /* Safari 3.1+ */ -moz-user-select: none; /* Firefox 2+ */ -ms-user-select: none; /* IE 10+ */ user-select: none; /* Standard syntax */ user-drag: none; -webkit-user-drag: none; }

When using electron if writing for a touchscreen device, you can simply use the following:

img, a {
    user-select: none;
    -webkit-user-drag: none;
}
