尝试模仿京东的“发现好货”模块的可用滑块滑动的缓动图

JS代码

function $(id) { return document.getElementById(id); }//缓动轮播图var fhTimer;var fhNum = 0;var barNum = 0;fhTimer = setInterval(marquee, 20);function marquee() { fhNum--; barNum = fhNum; if(fhNum < -2400) { fhNum = 0; } $("fhc_ul").style.left = fhNum + "px"; if(fhNum < -2400) { barNum = fhNum + 2400; } $("fhc_dBar").style.left = -(barNum / 2.75) + "px";}$("fhcShow").onmouseover = function() { $("fhc_d_box").style.display = "block"; clearInterval(fhTimer);}$("fhc_d_box").onmouseover = function() { $("fhc_d_box").style.display = "block";}$("fhcShow").onmouseout = function() { $("fhc_d_box").style.display = "none"; fhTimer = setInterval(marquee, 20);}//鼠标悬浮在标题也在暂停滚动$("fhTit").onmouseover = function() { clearInterval(fhTimer);}$("fhTit").onmouseout = function() { fhTimer = setInterval(marquee, 20);}//滑块$("fhc_dBar").onmousedown = function(event) { var event = event || window.event; var leftValue = event.clientX - this.offsetLeft; document.onmousemove = function(event) { var evt = event || window.event; var locationX = evt.clientX - leftValue; if(locationX < 0) { locationX = 0; } else if(locationX > 960 - 99) { locationX = 960 - 99; } $("fhc_dBar").style.left = locationX + "px"; fhNum = -locationX * 2.75; //如果选中了，就取消选中，防止出现bug window.getSelection ? window.getSelection().removeAllRanges() : document.selection.empty(); } document.onmouseup = function() { document.onmousemove = null;//取消注册的这个事件 }}
