Answer 1

在Firefox 29中，这在mousedown事件中有效（如果单击滚动条，则为true）：

if (e.explicitOriginalTarget.tagName === 'HTML')

Answer 2

The closest you'll get is

document.onscroll = function(){alert("you scrolled");}

or in jQuery

$(document).scroll(function(){alert("you scrolled");});

Different browsers handle it in different ways, generally they fire everytime the page moves a pixel or more. In Android browsers it only updates when you stop scrolling.
