【问题描述】：

我想在 ionic v1 中每天晚上 8 点发送通知。我已经引用了以下代码，但它给出了异常。此处应使用哪种日期时间格式。我从来没有在任何地方找到完整的代码。请帮帮我。

 document.addEventListener('deviceready', function () 
// Schedule notification for tomorrow to remember about the meeting
cordova.plugins.notification.local.schedule(
    id: 10,
    title: "Meeting in 15 minutes!",
    text: "Jour fixe Produktionsbesprechung",
    at: monday_9_am,
    data:  meetingId:"#123FG8" 
);

// Join BBM Meeting when user has clicked on the notification 
cordova.plugins.notification.local.on("click", function (notification) 
    if (notification.id == 10) 
        joinMeeting(notification.data.meetingId);
    
);

// Notification has reached its trigger time (Tomorrow at 8:45 AM)
cordova.plugins.notification.local.on("trigger", function (notification) 
    if (notification.id != 10)
        return;

    // After 10 minutes update notification's title 
    setTimeout(function () 
        cordova.plugins.notification.local.update(
            id: 10,
            title: "Meeting in 5 minutes!"
        );
    , 600000);
);
 , false);

【参考方案1】：

来自here：

cordova.plugins.notification.local.schedule(
    id: 1,
    title: "Message Title",
    message: "Message Text",
    firstAt: date, // firstAt and at properties must be an IETF-compliant RFC 2822 timestamp
    every: "week", // this also could be minutes i.e. 25 (int)
    sound: "file://sounds/reminder.mp3",
    icon: "http://icons.com/?cal_id=1",
    data:  meetingId:"123#fg8" 
);

具体来说：

// firstAt and at properties must be an IETF-compliant RFC 2822 timestamp

我相信你可以创建一个 JS Date 对象，然后运行.toUTCString() 来创建一个兼容的时间戳。
