Momentjs: Parse format like 'MM/DD/YYYY hmA' doesn't work

Question

I have a date string and try to parse it use moment.js:

var d = '06/09/2015 200AM';
var date = moment(d, 'MM/DD/YYYY hmmA');

However, the hour seems not right after parsing:

console.error(date.hours); //output: 20

Am I doing anything wrong here?

I guess if hour and minute are separated by a ':' would solve the problem, but the time was get from value of a and I don't like to put the ':' in it..

Thanks for all the help.

Answer 1

That's a very odd string format, one would normally expect a reliable two digits for that hour value. I think you're going to have to pre-process it.

var d = /*...get the string from wherever...*/;
var r = /^(\d{2}\/\d{2}\/\d{4}) (\d{3}..)$/
var m = r.exec(d);
if (m) {
    d = m[1] + " 0" + m[2];
}
var date = moment(d, 'MM/DD/YYYY hmmA');

Its because '06/09/2015 200AM' is an invalid date so it won't work. Here is a fiddle example of a the invalid datetime next to a valid datetime. Just play with this fiddle to get it right.

If you don't want to fix the date with colon and space. I've updated the fiddle to use javascript to inject the ':' and space for you:
