momentjs

问题 I have an array that is populated with moment(Date provided by the database) elements.

问题 Does momentjs provide any option to set time with particular time ? var date = "2017-03-13"; var time = "18:00"; var timeAndDate = moment(date).startOf(time); console.log(timeAndDate); <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script> 回答1: Moment.js does not provide a way to set the time of an existing moment through a string. Why not just concatenate the two: var date = "2017-03-13"; var time = "18:00"; var timeAndDate = moment(date + ' ' + time);

问题 I'm using moment.js and moment-timezone to get a local utc date string. I've created the function below to achieve this. When trying to use this when dealing with an Arabic locale I'm getting invalid date returned. function _getLocalUtcDateString(utcDateString, timezoneId) { var utcMoment = moment.utc(utcDateString, 'MM/DD/YYYY hh:mm:ss A').format('MM/DD/YYYY hh:mm:ss A'); var localTimeTz = moment.utc(utcMoment).tz(timezoneId).format('MM/DD/YYYY hh:mm:ss A'); return localTimeTz; } If I call

问题 I am using Moment.js for adding dates to an option list I am making, so that I can use those dates to show available appointments, for example, someone can select Friday, February 3rd from the option list and then a list of available times will show up for February 3rd. What I am having trouble with is I am using an online scheduling api that takes month values that start at 1, for example, January is 01, February is 02, etc. but moment.js months start at 0 and only go up to 11, for example,

问题 I have created an angular material date picker component to use with formly , and tried to set it to use GB for the locale so that dates are shown as 26/07/2019 . However, when typing in the date, it parses as US still, resulting in invalid date errors being shown. I have tried to include moment and the MomentDateAdapter module but have been unable to solve the issue. Here is a stackblitz I've set my providers like so: providers: [ { provide: LOCALE_ID, useValue: 'en-GB' }, { provide:

问题 I need to get the start date and end date in the below format using moment js startDate = 20160427000000 and endDate = 20160427235959 Here the start date appended with 000000 and end date appended with 235959 What is the right way to get this result in javascript 回答1: You want the format operator. Since it looks like your 0's and 2359's are hardcoded (I assume you're doing start and end of days), try: startDate = moment().format('YMMDD000000'); endDate = moment().format('YMMDD235959'); EDIT:
