这篇文章主要介绍了JS如何实现可用滑块滑动的缓动，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
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
}
