I have 2 inputs for datetime-local (start-time & end-time). I want to limit the start date to select only the last 72 hours which I did but i cannot restrict future time. I only want today and only last 3 days. And for end time only today and next 3 days. This is my code:
<input type="datetime-local" name="start_timestamp" id="start_timestamp" required>
<input type="datetime-local" name="end_timestamp" id="end_timestamp" required>
<script>
//Do not let to select START TIME in the PAST
var today = new Date();
var past = new Date(today.setDate(today.getDate() - 3)).toISOString().slice(0, 16);
document.getElementsByName("start_timestamp")[0].min = past;
document.getElementsByName("start_timestamp")[0].max = today;
</script>
See here a possible fix.
<input type="datetime-local" name="start_timestamp" id="start_timestamp" required>
<input type="datetime-local" name="end_timestamp" id="end_timestamp" required>
<script>
//Do not let to select START TIME in the PAST
let today = new Date();
let past = new Date(today.setDate(today.getDate() - 3)).toISOString().slice(0, 16);
today = new Date().toISOString().slice(0, 16);
document.getElementsByName("start_timestamp")[0].min = past;
document.getElementsByName("start_timestamp")[0].max = today;
document.getElementsByName("end_timestamp")[0].min = past;
document.getElementsByName("end_timestamp")[0].max = today;
</script>
