如何将此JSON数据格式化为日期（mm / dd / yyyy）

Question

Sample JSON:

[{"DispatchDt":"2014-05-28T01:34:00","RcvdDt":"1988-12-26T00:00:00"}]

I have this set of dates and I want to convert it to the date format (mm/dd/yyyy). How do you do this is JavaScript?

Answer 1

Unfortunately parsing and formatting dates is a weak side of javascript.

So usually for that we use the 3rd party libraries like moment.js

An example of how you would do that with moment.js :

var date = '2014-05-28T01:34:00';

var parsedDate = moment(date);

var formattedDate = parsedDate.format('MM/DD/YYYY');

You may format the json string into new Date() then use js methods to get month,day,year or what exactly you need.

   //format string to datetime
   var DispatchDt = new Date(this.DispatchDt);


   // then use this methods to fetch date,month, year needed
   //getDate() // Returns the date
   //getMonth() // Returns the month
   //getFullYear() // Returns the year
    var DispatchDt_date = DispatchDt.getDate();
    var DispatchDt_month = DispatchDt.getMonth() + 1; //Months are zero based
    var DispatchDt_year = DispatchDt.getFullYear();

This would work

var a = "[{"DispatchDt":"2014-05-28T01:34:00","RcvdDt":"1988-12-26T00:00:00"}]";
var b = JSON.parse(c);
for (i in b[0]) {
  b[0][i] = b[0][i].slice(0, 9) 
}
console.log(b); // b now looks like this [ { DispatchDt: "2014-05-28", RcvDt: "1988-12-26" } ]

Please note the dates are stringified.
