事件

javascript 复制代码

const state = reactive({
	selectTime: {
		time: '00:00' as any
	},
	meta_data_duration: 188 as any,
	minutes: null as any
});
// 数据处理
const makeRange = (start: number, end: number) => {
  const result: number[] = []
  for (let i = start; i <= end; i++) {
    result.push(i)
  }
  return result
}
// 小时
const disabledHours = () => {
  	return makeRange(0, 23)
}
// 分钟
const disabledMinutes = () => {
	const val = state.meta_data_duration
	const min = parseInt(val % 3600 / 60)
	state.minutes = min
	return makeRange(min, 59)
}
// 秒数
const disabledSeconds = (hour: number, minute: number) => {
	const val = state.meta_data_duration
	const sec = parseInt(val % 3600 % 60)
	if (state.minutes === minute + 1) {
		return makeRange(sec, 59)
	}
}

只显示分秒，隐藏小时，

javascript 复制代码

// 作用全局，为避免影响到其他页面样式，所以外层写一个单独的类名用于区分
<style lang="scss">
// 隐藏小时的代码
.noneMinute {
	.el-scrollbar:nth-of-type(1) {
		display: none !important;
	}
	//调整样式
	.el-time-spinner {
		width: 150%;
		white-space: nowrap;
	}
}
</style>
