鼠标移动时增加和减少滑动速度

Question

我正在尝试创建一个幻灯片，当您将鼠标向右移动并将其速度降低到左侧时，该幻灯片会提高其速度。问题是我希望它连续不连续。这是我的代码。谢谢你

$('[class*="sPrevious"]').hover(
                function () {
                    //debugger;
                    //$( "."+slideId+"_"+"ui" ).stop(true, false);
                    var cName = this.className.substr(11);
                    var slideId = cName.substring(0,cName.lastIndexOf("_"));
                    var totalSize = $('#'+slideId+"_totalWidth").attr( "value");
                    var mWidth=288;
                    var leftSize = $('.'+slideId+'_'+'ui').css("left");
                    leftSize = leftSize.substring(0,leftSize.lastIndexOf("p"));



                    $( '.'+slideId+'_'+'ui' ).animate(
                      { left: 0     },                        
                      {
                        duration: 3400*this.className.substr(9,1),
                        queue : false
                      }
                      );
