JS实现可用滑块滑动的缓动图

2024-12-01 21:39:07

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
    }
}

JavaScript Tween算法及缓动效果第1/2页

我这里要教大家的是怎么利用flash的Tween类的算法,来做js的Tween算法,并利用它做一些简单的缓动效果. Tween Tween类型: Linear Quadratic Cubic Quartic Quintic Sinusoidal Exponential Circular Elastic Back Bounce ease类型: easeIn easeOut easeInOut /* 算法来源:http://www.robertpenner.com/easing/ */ var Tw
JS+HTML5手机开发之滚动和惯性缓动实现方法分析

本文实例讲述了JS+HTML5手机开发之滚动和惯性缓动实现方法.分享给大家供大家参考,具体如下: 1. 滚动以下是三种实现方式: 1) 利用原生的css属性 overflow: scroll div id= parent style = overflow:scroll; divid='content'内容区域/div /div Notice: 在android 有bug, 滚动完后会回退到最顶端的内容区域,解决办法是使用后两种方式实现 2)js 编程实现思路:对比手指在屏幕上移动前后位置变化
JS轮播图中缓动函数的封装

轮播图的根本其实就是缓动函数的封装,如果说轮播图是一辆跑动的汽车,那么缓动函数就是它的发动机,今天本文章就带大家由简入繁,封装属于自己的缓动函数~~ 我们从需求的角度开始,首先给出一个简单需求: 1.我想让页面中的一个盒子从开始的位置匀速向右运动到200px的地方,该怎么实现? 分析: 1)我们需要知道盒子在哪个地方,这个可以通过offsetLeft属性去获取: 2)要让盒子匀速运动,对于js肯定需要setInterval了: 3)要让盒子向右边跑起来?那就是需要不停改变盒子与左边起始点的距离,
让div运动起来 js实现缓动效果

本文实例为大家分享了js实现缓动效果的具体代码,供大家参考,具体内容如下 var tween = { linear:function(t,b,c,d){ return c*t/d + b; }, easeIn:function(t,b,c,d){ return c * ( t /= d ) * t + b; }, strongEaseIn:function(t,b,c,d){ return c * ( t /= d ) * t * t * t * t + b; }, strongEaseOut:
tween.js缓动补间动画算法示例

一.理解tween.js 如果看到上面的已经理解了,可以跳过下面的部分.下面为对Tween.js的解释下面就介绍如何使用这个Tween了,首先b.c.d三个参数(即初始值,变化量,持续时间)在缓动开始前,是需要先确定好的. 首先引入一个概念就补间动画 Flash做动画时会用到Tween类,利用它可以做很多动画效果,例如缓动.弹簧等等. tween.js在Flash中可以解释为补间动画. 那么问题来了,什么是补间动画呢? 相信学过Flash的都知道补间动画是flash主要的非常重要的表现手段之一

js实现拖动缓动效果

话不多说,先上效果,一个体验非常好的拖拽缓动的效果,让页面提升一个档次. 这个效果看似很简单,到也困惑了很长时间,为什么别人写出来的拖拽体验为什么这么好? 直到我自己实现了以后,才发现,原来我想的实现方式不对.接下来,我通过简短的几句话,来提供这个功能的实现思路. 首先,我们要明白,我们鼠标拖拽是在一个2d平面上拖拽 2d平面只有x轴和y轴,而且获取的拖拽值也是基于平面的像素获取的.所以,我们第一步,先通过鼠标事件来获取到当前的拖拽的长度像素. 首先,绑定鼠标按下事件,来获取到鼠标基于浏览器窗口
