How to convert html5 input time to a timestamp in JavaScript?

Question

Let's say I have 2:12 PM as my time from an input, and I want to convert it to a timestamp combined with the current date.

I can get the current timestamp using Date.now() but my problem is I want the time to be based on the input.

If moment can be used, then better. Any help would be much appreciated.

And you're not capable to read the [documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date)? — Teemu, Sep 14 '17 at 06:17

You could pass in the time format to moment's constructor, along with the input's value as string to parse it into a moment object. Like this:

console.log(moment('2:12 PM',"hh:mm a").format('lll'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

You should be able to use momentJS custom parsing:

moment("2:12 PM", "H:mm A");

Using simple JavaScript

Done, It's in j

One line solution:

var d = new Date();
var ty = "11:22:00";
var newDate = new Date(d.toString().split(":")[0].slice(0,-2) + ty);

It's the full date, you can use and change it as you like.
