我嘗試使用 jQuery (jquery-1.7.1.min.js) 滾動，mouseover但無法滾動。下面是我的代碼。var ele = $('html,body');var speed = 1,  scroll = 3,  scrolling;$('#up').mouseenter(function() {  //scroll the element up  scrolling = window.setInterval(function() {    ele.scrollTop(ele.scrollTop() - scroll);  }, speed);});$('#down').mouseenter(function() {  //scroll the element down  scrolling = window.setInterval(function() {    ele.scrollTop(ele.scrollTop() + scroll);  }, speed);});$('#up, #down').bind({  click: function(e) {    //stop scrolling    if (scrolling) {      //prevents the default click action      e.preventDefault();    }  },  mouseleave: function() {    if (scrolling) {      window.clearInterval(scrolling);      scrolling = false;    }  }});.control {  width: 100%;  position: fixed;  text-align: center}#up.control {  position: fixed;  top: 0}#down.control {  position: fixed;  top: 20}/* no needed: */#scroll {  overflow-x: scroll;  width: 500px;  white-space: nowrap;  overflow: hidden!imprtant;}onmouse左側和右側需要從左到右和從左到右滾動文本，但它無法使用 jQuery。
