业务需求：数据大屏页面中的某个方法需要在今天12:00执行一次，或是在今天的17:00执行一次，

这里用到 setTimeout定时器来实现。

//获取某个时间的时间戳   getCurrentDate(time) {let now = new Date();let year = now.getFullYear();let month = now.getMonth() + 1;let day = now.getDate();return year + "-" + month + "-" + day + ' ' + time},mounted(){let timeList = ['7:35:00', '17:05:00']timeList.forEach(item => {let nowtime = new Date().getTime()let onetime = new Date(this.getCurrentDate(item)).getTime()if (nowtime > onetime) {return} else {let t = (onetime - nowtime)setTimeout(() => {//要执行的方法}, t)}})
}
