@H_404_1@当我从$(窗口)“向上”滚动时,我希望得到一个事件.scrollTop == 0.
@H_404_1@如果您有以下代码：
@H_404_1@
$(window).scroll(function(){
console.log("scrolling")
});
最佳答案

$(document).on('mousewheel DOMMouseScroll MozMousePixelScroll',function(event,delta) {
console.log('mousewheel');
//you could trigger window scroll handler
$(window).triggerHandler('scroll');
});
document.addEventListener('scroll',function (event) {
var $elm = $(event.target);
if ($elm.is('textarea')) { // or any other filtering condition
// do some stuff
var direction = $elm.scrollTop() > ($elm.data('scrollTop') || 0) ? "down" : "up";
$elm.data('scrollTop',$elm.scrollTop());
console.log('scrolling',direction);
}
},true);
