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
@H_502_5@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 } }
