Javascript 静态主体滚动上的滚动DIV

我有一个静态主体元素和一个DIV，它的高度是500px。它有溢出：可见和文本长度超过500px。我想滚动那个DIV，而我的鼠标指针在主体上，主体本身并没有任何滚动条

有什么方向吗

-鼠标指针在我要滚动的DIV之外

您可以试试

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

好的，我找到了。对于找到此线程的任何人：

/** 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;

到目前为止，您尝试了什么？将DIV设置为position:fixed，并将其顶部、底部、左侧和右侧设置为0，但它会调整其内部元素的大小，以便基本上您希望在鼠标指针不在其内部时滚动它？是的，这就是我想做的。我讨厌这里的家伙欺负新人，不去投票，删除他们的问题，而不是纠正和帮助他们：/
