使用Modernizr检测拖放（不是文件拖放）

Question

I've spent a fair while looking for the answer to this question and either found answers that are out of date or answers that relate to file drag and drop.

I just want to check if a user's browser supports HTML5 drag and drop. At the moment the line...

if (!Modernizr.draganddrop) {
   // non-HTML5 alternative drag and drop code here
}

...returns true for any IE version I emulate. Why does Modernizr think that IE doesn't support drag and drop at all? I read that IE9 onward does...

Should I be checking the browser version instead?

Any help, much appreciated.

Answer 1

Just use javascript rather than Modernizr:

function dragAndDropSupported () {
    return 'draggable' in document.createElement('span');
}

Check to see if dragAndDropSupported() === true
