uniapp开发一个微信小程序，需要用到一个日历排班功能。
但是遇到一个问题就是，点击更新了内容后，日历上的自定义内容没有更新。排查发现组件只会在show变化时才会更新。修改了一下源文件搞定。

找到 uview/uni_modules/uview-ui/components/u-calendar/u-calendar.vue文件。
找到这一段在this.innerFormatter = e下面追加一段。this.setMonth()就可以了。

		// 在微信小程序中，不支持将函数当做props参数，故只能通过ref形式调用
		setFormatter(e) {
			this.innerFormatter = e
			this.setMonth()
		},

使用实例完整代码

<template>
	<view>
		<u-calendar :maxDate="maxDate" title="可服务时间" @close="gethide" :show="show" :mode="mode" @confirm="confirm"
			ref="calendar" monthNum="5" mode="single" :show-confirm="false">
		</u-calendar>

	</view>
</template>

	const date = d.getDate()
	export default {
