API

属性	类型	默认值	必填	说明
indicator-dots	boolean	false	否	是否显示面板指示点
indicator-color	color	rgba(0, 0, 0, .3)	否	指示点颜色
indicator-active-color	color	#000000	否	当前选中的指示点颜色
autoplay	boolean	false	否	是否自动切换
current	number	0	否	当前所在滑块的 index
interval	number	5000	否	自动切换时间间隔
duration	number	500	否	滑动动画时长
circular	boolean	false	否	是否采用衔接滑动
vertical	boolean	false	否	滑动方向是否为纵向
previous-margin	string	"0px"	否	前边距，可用于露出前一项的一小部分，接受 px
next-margin	string	"0px"	否	后边距，可用于露出后一项的一小部分，接受 px
bindchange	eventhandle		否	current 改变时会触发 change 事件，event.detail = {current}

• previous-margin、next-margin需配合swiper-item使用，设置在swiper-item上生效
• current改变时会切换至所在滑块。若两次设置相同的current，则不会产生切换
