Answer 1

您可以尝试

$(document).ready(function(){
   if ($('selector:hover').length != 0) {
    $(document).scrollTo('selector');
 }
});

好吧，我找到了它。对于任何找到此线程的人：

/** This is high-level function.
* It must react to delta being more/less than zero.
*/
function handle(delta) {
var target = $('#scrollable_content');
var top = target.scrollTop() - delta;
target.scrollTop(top);
}
/** Event handler for mouse wheel event.
*/
function wheel(event){
var delta = 0;
if (!event) /* For IE. */
        event = window.event;
if (event.wheelDelta) { /* IE/Opera. */
        delta = event.wheelDelta/120;
} else if (event.detail) { /** Mozilla case. */
        /** In Mozilla, sign of delta is different than in IE.
         * Also, delta is multiple of 3.
         */
        delta = -event.detail/3;
}
/** If delta is nonzero, handle it.
 * Basically, delta is now positive if wheel was scrolled up,
 * and negative, if wheel was scrolled down.
 */
if (delta) handle(delta);
/** Prevent default actions caused by mouse wheel.
 * That might be ugly, but we handle scrolls somehow
 * anyway, so don't bother here..
 */
if (event.preventDefault) event.preventDefault();
event.returnValue = false;
}

if (window.addEventListener) window.addEventListener('DOMMouseScroll', 
wheel, false);
window.onmousewheel = document.onmousewheel = wheel;
