javascript - 获取时间(以毫秒为单位)，对应自定义字符串

Question

假设我有一个“事件”数组，其中包含“事件”对象，如下所示:

var events = [
    {
        name: 'event1',
        start: '10.30',
        end: '10.45'
    },{
        name: 'event2',
        start: '11.00',
        end: '12.00'
    }
]

现在，我将有一个超时函数执行以下操作:

setTimeout(function() {
    var currentTime = Date.now();

    // how can i transform the start and end times from the events object in milliseconds?

    var startEventOne = events[0].start // -> how can I transform the string 10.30 in milliseconds?

}, 1000);

问题是，如何获得相当于输入字符串的以毫秒为单位的时间？这可能吗？

嘿，

var timeArr, 
    hours,
    minutes,
    milliseconds,
    date;

timeArr = events[0].start.split('.');
hours = timeArr[0];
minutes timeArr[1];
date = new Date(0, 0, 0, hours, minutes, 0, 0);
milliseconds = date.getTime();
// This will return you the number of milliseconds
