Disable previous today's previous time in html input datetime-local picker

问题

I am trying to figure out solution to fix the issue of not allowing user to select previous time. I mean for eg

Today's date: 17-02-2019
Current Time: 02:30 PM

So when user selects today's date and selects the time 02:30 AM instead of PM. Here the time is past so user shouldn’t be allowed to select the AM time because the current time is 02:30 PM

As per MDN docs the below code should work but it’s not working.

   <input type="datetime-local" min="2019-02-17T14:30" />

As per below docs it shouldn’t allow me to select time like eg 9:00 AM, 10:00 AM even 02:29 PM but I am allowed to select. I even tried their fiddle example but their examples do allow me to select past time

This may be because of the format , you may need to strip off the seconds. In console.log you can see the seconds but when setting the min value the seconds and microseconds need to strip off

var today = new Date().toISOString();
console.log(today)
document.getElementById("daTi").min = '2019-02-17T10:38';

<input type="datetime-local" id='daTi' />
