效果如下图：在线预览

APIs

Segmented

参数	说明	类型	默认值	必传
block	是否将宽度调整为父元素宽度，同时所有选项占据相同的宽度	boolean	false	false
disabled	是否禁用	boolean	false	false
options	选项数据	string[] | number[] | SegmentedOption[]	[]	false
size	控件尺寸	‘large’ | ‘middle’ | ‘small’	‘middle’	false
value v-model	当前选中的值	string | number	undefined	false

SegmentedOption Type

名称	说明	类型	必传
label	选项名	string	false
value	选项值	string | number	true
disabled	是否禁用选项	boolean	false
payload	自定义数据载体	any	false

Events

名称	说明	类型
change	选项变化时的回调函数	(value: string | number) => void

创建分段控制器组件Segmented.vue
