Question

JavaScript regex to format Form Field

Updated June 27, 2017

asked on June 25, 2017 • Show version history

I am trying to format a field in a Form that shows a Date Of Birth plus the time. I need to only show the date.

Example - 23/06/2000 00:00:00

I would imagine that the regex would be something like this - (\d\d\/\d\d\/\d\d\d\d)\s00:00:00

How do I use it with JavaScript?

Answered my own question -

$(document).ready(function () {

var re = new RegExp("(\\d\\d\\/\\d\\d\\/\\d\\d\\d\\d)\\s00:00:00");

$('#q3 input').on('change', function() {
var pm = $(this).val().match(re);
$('#q42 input').val(pm[1]).trigger('change');
});
});

If the time is always "00:00:00" you could also .replace() instead of regex.

var pm = $(this).val().replace(" 00:00:00","");
