vue引用该单文件组件，会在页面显示一个输入框，点击后出现日期选择器。但是页面调用需要获取父组件的默认值并向父组件传递日期选择结果。（默认为空时可以不向子组件传值）
<datePickers v-on:datatime="datatime" :oldTime="$store.state.Jtnc.seeobjs.DJSJ" v-if="isRouterAlive" class="inputStyle" ></datePickers>
v-on:datatime="datatime"向子组件传递了一个方法，子组件调用方法后可将选定日期值值传回父组件。
父组件方法：datatime
/*时间处理*/
datatime(theTime){
this.modifyModel.DJSJ = theTime;
},
子组件调用（在选择日期的方法selectDay中调用）：
this.$emit('datatime',this.date);
:oldTime="$store.state.Jtnc.seeobjs.DJSJ"将默认的日期值传入子组件，子组件通过props接收，看到组件时将看到默认日期。
props: {
oldTime: ""
}
v-if="isRouterAlive"为强制刷新组件的开关，由于该组件会在打开页面时加载，而默认日期如果在打开模态框时传入，所以在打开模态框时强行刷新组件，可看到默认日期。
将数据渲染在模态框中是调用this.reload()刷新组件。（https://www.cnblogs.com/s313139232/p/9176820.html）
/*组件刷新*/
reload () {
this.isRouterAlive = false;
this.$nextTick(() => (this.isRouterAlive = true))
},
