I need to validate the date from the user and check if it is in a particular format. If yes, then it will be accepted else it will not be. I am looking for sort of
value.match("regular expression")
The above works fine if, I have to choose from few formats. So, I came across this moment.js and interested in knowing how to use isSame(). I tried implementing it but unsuccessful. Like :
var x=moment("MM/DD/YYYY") ;
x.isSame("28-02-1999"); // am getting false which is right
var x=moment("28-02-1999","DD-MM-YYYY") ;
x.isSame("28-02-1999"); // am getting false which is wrong
So, please help in that. Thanks
Check if a moment is the same as another moment.
moment('2010-10-20').isSame('2010-10-20'); // trueIf you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.
moment('2010-10-20').isSame('2009-12-31', 'year'); // false
moment('2010-10-20').isSame('2010-01-01', 'year'); // true
moment('2010-10-20').isSame('2010-12-31', 'year'); // true
moment('2010-10-20').isSame('2011-01-01', 'year'); // false
Your code
var x=moment("28-02-1999","DD-MM-YYYY"); // working
x.isSame("28-02-1999"); // comparing x to an unrecognizable string
If you try moment("28-02-1999"), you get an invalid date. So comparing x to an invalid date string returns false.
To fix it, either use the default date format (ISO 8601):
var x = moment("28-02-1999","DD-MM-YYYY");
x.isSame("1999-02-28"); // YYYY-MM-DD
Or pass isSame a moment object.
var x = moment("28-02-1999","DD-MM-YYYY");
x.isSame( moment("28-02-1999","DD-MM-YYYY") );
