阅读更多关于 Parse 'Date & Time' string in Javascript which are of custom format

问题 I have to parse a date and time string of format "2015-01-16 22:15:00". I want to parse this into JavaScript Date Object. Any help on this? I tried some jquery plugins, moment.js, date.js, xdate.js. Still no luck. 回答1: With moment.js you can create a moment object using the String+Format constructor: var momentDate = moment('2015-01-16 22:15:00', 'YYYY-MM-DD HH:mm:ss'); Then, you can convert it to JavaScript Date Object using toDate() method: var jsDate = momentDate.toDate(); 回答2: A better

问题 Using Date.js already, but can also use another library if necessary. Not sure what is the best way to work with time deltas. Specifically, I want to display the time that has elapsed between now and a past date-time. So I need to do something like this: var elapsed_time = new Date() - pastDate; pastDate.toString('days-hours-minutes-seconds'); Gotten it to mostly work using Date.js, but the problem is now I'm working with a Date object and not a timespan, so what should be an 23 hour time

Javascript using datejs to parse RFC3339 datetime

阅读更多关于 Javascript using datejs to parse RFC3339 datetime

问题 I'm having trouble using datajs with a date format from Google Calendar API. The datetime format I believe is RFC3339 and this is a sample datetime returned from the calendar api 2012-01-05T08:45:00Z This is from the datejs documentation here Date.parse('1985-04-12T23:20:50Z') // RFC 3339 Formats But this just returns null. I'm assuming I have datejs working correctly as Date.today().next().friday() returns Fri May 11 2012 00:00:00 GMT+0100 (BST) 回答1: SOLVED : Use Date.parseExact OR this

问题 I have DateJS set up on my website to give users the ability to know when they will receive their package. I am utilizing DateJS script to do this.

Convert JavaScript DateTime to UTC with no milliseconds

问题 Right now I'm trying to parse a date that's written in a human-readable format into a DateTime String that a SharePoint list will accept. In order to do this I've determined that I need a String in a format similar to ISO that looks like: 2007-08-20T00:00:00Z . It seems that SharePoint only accepts DateTimes that are in UTC with no milliseconds included (for whatever reason, SharePoint gives errors and won't accept the DateTime when you include the milliseconds), so I need to convert my local

问题 I'm including the date.js library in my site because I need its functionality. I have just realized, though, that the standard Javascript parse() method is overwritten by it. I'm trying to build a line chart in Highcharts, and the data series wants the first element to be be in milliseconds (their demos show them using the Date.UTC() method to achieve this, but my data is returned in a different format). Short of doing a bunch of string manipulation to put my data into a format that Date.UTC

问题 Am I missing something with Date.parseExact() in date.js? According to the api documentation, I should be able to do this: Date.parseExact("10/15/2004", ["M/d/yyyy", "MMMM d, yyyy"]); // The Date of 15-Oct-2004 That is, I should be able to pass in a string array which contains "...the expected format {String} or an array of expected formats {Array} of the date string." However, when I do this: var d = Date.parseExact($(this).val(), ["MMddyy", "Mddyyyy", "MM/dd/yy","MM/dd/yyyy"]) I get back

问题 I'm using DateJS to parse user-inputted dates, and getting some strange results. Date.parse("15 Jan 2010") returns Fri Jan 15 00:00:00 EST 2010 (right) Date.parse("15-Apr-2010") returns Thu Apr 15 00:00:00 EDT 2010 (right) Date.parse("15 Apr 2010") returns Thu Apr 1 00:00:00 EDT 2010 (wrong) As far as I can tell, the d MMM yyyy input format works fine for every month except April and August; in those two cases, it returns the first of the month no matter what day is entered. Is this a bug, or

我注意到JavaScript的 new Date() 函数非常聪明，可以接受多种格式的日期。 Xmas95 = new Date("25 Dec, 1995 23:15:00") Xmas95 = new Date("2009 06 12,12:52:39") Xmas95 = new Date("20 09 2006,12:52:39") 在调用 new Date() 函数时，找不到任何显示所有有效字符串格式的文档。这是用于将字符串转换为日期。如果我们从相反的角度来看，也就是将日期对象转换为字符串，直到现在，我仍然觉得JavaScript没有内置的API将日期对象格式化为字符串。编者按：以下方法是提问者的企图是工作在一个特定的浏览器，但一般不工作; 请参阅本页上的答案以查看一些实际解决方案。今天，我在date对象上使用 toString() 方法，令人惊讶的是，它用于将日期格式化为字符串的目的。 var d1 = new Date(); d1.toString('yyyy-MM-dd'); //Returns "2009-06-29" in Internet Explorer, but not Firefox or Chrome d1.toString('dddd, MMMM ,yyyy') //Returns "Monday, June 29,2009" in
