momentjs

问题 I have the following code : var fomattedDate = moment(myDate).format("L"); Sometimes moment(myDate).format("L") returns "Invalid date", I want to know if there is a way to prevent that and return an empty string instead. 回答1: TL;DR If your goal is to find out whether you have a valid date, use Moment's isValid : var end_date_moment, end_date; jsonNC.end_date = jsonNC.end_date.replace(" ", "T"); end_date_moment = moment(jsonNC.end_date); end_date = end_date_moment.isValid() ? end_date_moment

问题 I want to convert my date time values to Unix timestamp format (basically an epoch timestamp). For that I use: let startDate = '2018-09-28 11:20:55'; let endDate = '2018-10-28 11:20:55'; let test1 = startDate.unix(); let test2 = endDate.unix(); However it gives me an error ERROR TypeError: Cannot read property 'Unix' of undefined Can anyone tell me how I can convert datetime to Unix using MomentJS? 回答1: The issue is because you're calling unix() on plain strings.

问题 Hi everyone I have looked at a few SO questions but have yet to find a solid answer to my problem. Question I have already looked at include: Moment.js returning wrong date Moment JS - parse UTC and convert to Local and vice versa My question is the following: I have a basic time selector with times ranging from 4:00am - 8:00pm.

问题 My code looks as following: const columns = [{ dataField: 'Id', text: 'Order ID' }, { dataField: 'Date', text: 'Date' }, { dataField: 'Total', text: 'Total' }]; And it displays date in React Bootstrap table. But, the date is in Json format that I don't need. I've tried to use the moment library to format date in this way: const columns = [{ dataField: 'Id', text: 'Order ID' }, { dataField: '{moment(Date).format("DD-MM-YYYY")}', text: 'Date' }, { dataField: 'Total', text: 'Total' }]; But, the

问题 I'm trying to get my datatables with dates entered in the D-MMM-YY format to be sorted but it doesn't appear to do so, only by the 1st digit in the date. For example, it sorts 9-Sep-13 before 1-Jun-20. A typical table line is as follows: <tr> <td>25-Jul-11</td> <td>Announcement</td> <td><a href="#">#</a></td> </tr> My javascript is as follows: <script type="text/javascript"> $(document).ready(function() { $.fn.dataTable.moment( 'D-MMM-YY'); $('#pn2020').DataTable({ "pageLength": 20, order: [[

问题 Looking for solution to restrict chat member with restrictChatMember() but unfortunately it still restrict the user forever not for 24 hours. const { date:joinDate } = ctx.message; const releaseDate = moment.unix(joinDate).add(1, 'day'); ctx.telegram.restrictChatMember( ctx.chat.id, memberID, releaseDate, false, false, false, false ); Reference: https://core.telegram.org/bots/api#restrictchatmember 回答1: You're passing a moment object back into the function, not an UNIX timestamp like the docs
