可配置参数

Prop	Type	Required	Default	Description
slider-id	Number	Y	1	slider的id，避免页面多个ep-slider导致获取错误
card-length	Number	Y	1	slider中item的数量
select-index	Number	N	0	默认突出item的index
enable-swipe	Boolean	N	true	是否需要滑动效果
container-s	Object	Y	{position: 'relative',width: 750,height: 352,overflow: 'hidden'}	包裹容器的样式
card-s	Object	Y	{width: 360,height: 300,spacing: 0,scale: 0.75}	item容器的样式
auto-play	Boolean	N	false	是否需要自动播放
interval	Number	N	1200	自动播放时候的间隔

• *ios中需同时设置container-s和card-s高度才生效

API说明

//ios下当放在list中，cell被回收后，导致下次appear的时候，手势失效了，需要再手动调用api，重新绑定下pan事件
// 直接在lc-ep-slider组件上面绑定ref="lc-ep-slider"
this.$refs['lc-ep-slider'].rebind();

主动触发设置

// 直接在lc-ep-slider组件上面绑定ref="lc-ep-slider",然后调用即可
// 譬如设置第二张
this.$refs['lc-ep-slider'].manualSetPage(1);

事件回调

//当前滑块被选中的回调
`v-on:LcEpSliderCurrentIndexSelected="LcEpSliderCurrentIndexSelected"`
