jquery convertion from string to time
提问by sisko
I have a system in development which records various times of the day in the following format: 06:53:22or 19:23:58as examples.
我有一个正在开发的系统，它以以下格式记录一天中的不同时间： 例如 06:53:22或19:23:58。
Can anyone tell me if it is possible to convert this string into javascript construct which I can use to compare times of the day?
谁能告诉我是否可以将此字符串转换为 javascript 构造，我可以用它来比较一天中的时间？

You can parse the time with this:
你可以用这个解析时间：
function timeToSeconds(time) {
time = time.split(/:/);
return time[0] * 3600 + time[1] * 60 + time[2];
}
It returns a number of seconds since 00:00:00, so you can compare the results easily:
它返回自 00:00:00 以来的秒数，因此您可以轻松比较结果：
timeToSeconds('06:53:22') < timeToSeconds('19:23:58')

var startTime = "19:23:58";
var endTime = "06:53:22";
var startDate = new Date("1/1/1900 " + startTime);
var endDate = new Date("1/1/1900 " + endTime);
if (startDate > endDate)
alert("invalid time range");
else
alert("valid time range");
js is smart enough to figure it out :)
js 足够聪明，可以弄清楚:)

of course you can do it, but before you should parse this string. date = new Date(year, month, day, hours, minutes, seconds, milliseconds)- we creaeted new object. After we can use date.getTime()date.getFullYear..
当然你可以这样做，但在你应该解析这个字符串之前。 date = new Date(year, month, day, hours, minutes, seconds, milliseconds)- 我们创建了新对象。在我们可以使用date.getTime()date.getFullYear..
