将Google日历事件结束时间添加到脚本中

我有一个脚本，它列出了谷歌日历事件的开始时间、名称和描述，但我也想有结束时间，这样它就可以读取；

5:00pm-6:00pm-事件标题-事件描述

而不仅仅是它目前所拥有的，这只是开始时间，而不是结束时间。

这是我的脚本：

$(document).ready(GCalEvents());
function GCalEvents() {
    var datenow = new Date();
    var curyear = datenow.getFullYear();
    var curmonth = datenow.getMonth() + 1;
    var curdate = datenow.getDate();
    var curhour = datenow.getHours();
    var curmin = datenow.getMinutes();
    var curtz = datenow.getTimezoneOffset();
    //curtz = -480;
    var plusmin = "-";
    if (curtz <= 0) {
        plusmin = "%2B";
    }
    curtz = Math.abs(curtz);
    var curtzmin = curtz % 60;
    curtz = parseInt(curtz / 60);
    if (curtzmin < 10) { curtzmin = "0" + curtzmin; }
    if (curtz < 10) { curtz = "0" + curtz; }
    datenow = curyear + "-" + curmonth + "-" + curdate + "T" + curhour + "%3A" + curmin + "%3A00" + plusmin + curtz + "%3A" + curtzmin;
    var url =  "https://www.googleapis.com/calendar/v3/calendars/{calendarid}/events?alwaysIncludeEmail=false&maxResults=2&orderBy=startTime&showDeleted=false&showHiddenInvitations=false&singleEvents=true&timeMin=" + datenow + "&fields=items(start%2Csummary%2Cdescription)%2CtimeZone&key={key}";
//    var url =  "https://www.googleapis.com/calendar/v3/calendars/{calendarid}/events?alwaysIncludeEmail=false&maxResults=2&orderBy=startTime&showDeleted=false&showHiddenInvitations=false&singleEvents=true&timeMin=" + datenow + "&fields=items(start%2Csummary%2Cdescription)%2CtimeZone&key={key}";
    $.getJSON(url, function(data) {
    var event_start_date_new = new Date();
    event_start_date_new.setDate(event_start_date_new.getDate() - 1);
    for(i in data['items']) {
            item = data['items'][i];
        // event title
            var event_title = item.summary;
            var event_description = item.description;
        // event start date/time
            var event_start_date = new Date(item.start.dateTime);
        // format the date and time
            var month = event_start_date.getMonth();
            var day = event_start_date.getDay();
            var date = event_start_date.getDate();
            var daysArr = new Array();
            daysArr[0] = "Sunday";
            daysArr[1] = "Monday";
            daysArr[2] = "Tuesday";
            daysArr[3] = "Wednesday";
            daysArr[4] = "Thursday";
            daysArr[5] = "Friday";
            daysArr[6] = "Saturday";
            var monthsArr = new Array();
            monthsArr[0] = "January";
            monthsArr[1] = "February";
            monthsArr[2] = "March";
            monthsArr[3] = "April";
            monthsArr[4] = "May";
            monthsArr[5] = "June";
            monthsArr[6] = "July";
            monthsArr[7] = "August";
            monthsArr[8] = "September";
            monthsArr[9] = "October";
            monthsArr[10] = "November";
            monthsArr[11] = "December";
            var hour = event_start_date.getHours();
            var min = event_start_date.getMinutes();
            if (min < 10) { min = "0" + min; }
            if (hour < 11) {
        var ampm = "am";
        if (hour == 0) { hour = 12; }
            } else {
        var ampm = "pm";
        if (hour > 12) { hour = hour - 12; }
            }
            if (hour < 10) { hour = "&nbsp;&nbsp;" + hour; }
            var event_start_str = daysArr[day] + ", " + monthsArr[month] + " " + date;
            var event_time_str = hour + ":" + min + " " + ampm;
            if (event_start_date.getDate() != event_start_date_new.getDate()) {
        event_start_str = "<div class='"calendar_date'"><strong>" + event_start_str + "</strong></div>";
        event_start_date_new = event_start_date;
            } else {
        event_start_str = "";
            };

            // Render the event
            $("#gcal-events").last().before("<div class='"calendar_item'"><li>" + event_time_str + "&nbsp;-&nbsp;" + event_title + "<p><small>" + event_description + "</small></p></ul>" + "</li></div>");
    }
    });
};

如果有人能够帮助恢复当前脚本，那就太好了。
