* @property {Array} list 标签数组,元素为对象,如[{name: '推荐'}]
* @property {String | Number} duration 滑块移动一次所需的时间,单位秒(默认 200 )
* @property {String | Object} activeStyle 菜单选择中时的样式(默认{ color: '#303133' }
* @property {String | Object} inactiveStyle 菜单非选择中时的样式(默认{ color: '#606266' }
* @property {String | Number} lineWidth 滑块长度(默认 20
* @property {String | Number} lineHeight 滑块高度(默认 3
* @property {String} lineColor 滑块颜色(默认:'#3c9cff'
* @property {String} lineBgSize 滑块背景显示大小,当滑块背景设置为图片时使用(默认 cover)
* @property {String | Number} itemStyle 菜单item的样式(默认 { height: '44px' }
* @property {String} scrollable 菜单是否可滚动,选项很少的时候设置为false整个tabs自动居中显示(默认:true)
* @property {String | Number} current 当前选中标签的索引(默认 0 )
* @property {String} keyName 从list元素对象中读取的键名(默认 'name'
* @property {String | Number} swierWidth swiper的宽度(默认 '750rpx'
* @property {String | Object} customStyle 自定义外部样式
*
* @event {Function(index)} change 标签改变时触发 index: 点击了第几个tab,索引从0开始
