Swipe JS 是一个轻量级的移动滑动组件,支持 1:1 的触摸移动,阻力以及防滑性能都不错,可以让移动web应用展现更多的内容,能解决我们对于移动Web对滑动的需求。
官网:http://www.swipejs.com
github:https://github.com/bradbirdsall/Swipe
要实现Swipe的滑动和手势非常简单,仅需要遵循一个简单的规则。下面是一个例子:
<div id='slider' class='swipe'> <div class='swipe-wrap'> <div>1</div> <div>2</div> <div>3</div> </div> </div>
里面包裹的三个DIV即是滑动的模块了,在滑块结束后面或页面底部添加事件代码:
window.mySwipe = Swipe(document.getElementById('slider'));
当然添加了事件后我们还需要添加一些基础的样式,以保证滑块能正常工作:
.swipe { overflow: hidden; visibility: hidden; position: relative; } .swipe-wrap { overflow: hidden; position: relative; } .swipe-wrap > div { float:left; width:100%; position: relative; }
到这里整个滑动效果就制作完成了,赶紧用手机进行测试下吧!
Swipe2.0还提供了更多的参数设置:
startSlide Integer (default:0) - index position Swipe should start at(滑动的索引值,即从*值开始滑动,默认值为0)
speed Integer (default:300) - speed of prev and next transitions in milliseconds.(滑动的速度,默认值300毫秒)
auto Integer - begin with auto slideshow (time in milliseconds between slides)(自动滑动,单位为毫秒)
continuous Boolean (default:true) - create an infinite feel with no endpoints(是否循环滑动,默认值为true)
disableScroll Boolean (default:false) - stop any touches on this container from scrolling the page(停止任何触及此容器上滚动页面,默认值flase)
stopPropagation Boolean (default:false) - stop event propagation(停止事件传播,默认值flase)
callback Function - runs at slide change.(回调函数)
transitionEnd Function - runs at the end slide transition.(滑动过渡时调用的函数)
举个带参数设置的栗子:
<script type="text/javascript">
window.mySwipe = new Swipe(document.getElementById('slider'), {
startSlide: 2,
speed: 400,
auto: 3000,
continuous: true,
disableScroll: false,
stopPropagation: false,
callback: function(index, elem) {},
transitionEnd: function(index, elem) {}
});
</script>
Swipe2.0提供的API
prev()
slide to prev(上一页)
next()
slide to next(下一页)
getPos()
returns current slide index position(获取当前索引位置)
getNumSlides()
returns the total amount of slides(获取所有滑块总数)
slide(index, duration)
slide to set index position (duration: speed of transition in milliseconds)(指数,持续时间)滑动设置索引位置(持续时间:转型速度以毫秒为单位)
与1.0相比较,2.0做出了很多改进,有更多的API设定,相比各种WebApp开发框架,Swipe也有自己的优缺点,
优点:
滑动与防滑性能非常不错,用户体验较好
Html结构简单,自定义较灵活
缺点:
切换后盒子的高度取决于切换内容最大高度,如果某个盒子无内容,那么会出现一个空白区域
当前选中状态在滑动结束后才激活
混合开发时js代码较为繁琐
