Find Whether the clipboard has text or image?

I am using Html5 and Jquery. I have paste image/text from clipboard into html canvas.

Is it possible to detect whether clipboard has text or image?

$(document).on('paste','[contenteditable]',function(e) {
    e.preventDefault();

    //Here is it possible to detect whether clipboard has text or image?

    var text = (e.originalEvent || e).clipboardData.getData('text/plain');
});

Thanks!
