I need to convert a in a timestamp, this is my html code:
<input type="date" name="date_end" id="date_end">
This field has a value that I have put like 25/10/2017 My jquery code is:
var dataEnd = $('[name="date_end"]').val();
if (!dataEnd) {
return false;
} else {
var timestamp_end=$('[name="date_start"]').val().getTime();
console.log("TIMESTAMP END "+timestamp_end);
.....
}
But this is not work, anyone can help me?
do this
var dateEnd = $('#date_end').val()
var var timestamp_end = Date.parse(date_end)
or in a single line
var timestamp_end = Date.parse($('#date_end').val())
it works and it's clean
make a new Date()
passing the value of your input as parameter, then call getTime()
. here an example:
$('[name="date_end"]').on('change',function() { var dataEnd = $(this).val(); console.log((new Date(dataEnd)).getTime()); })
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="date" name="date_end" id="date_end">
Here is a Solution ( Using pure js ) , I used the unary plus operator operator after converting the value into javascript date object.
function checkDateValue(){ var dateConvertedToTimestamp = (+new Date(document.getElementById('date_value').value)); document.getElementById('date_value_timestamp').innerHTML = dateConvertedToTimestamp ; }
<input type='date' id='date_value'> <button onClick='checkDateValue()'> Submit </button> <div>Timestamp:- <span id='date_value_timestamp'></span></div>
I needed an UNIX timestamp and updated Partha Roy's anwser for my needs.
Javascript :
document.getElementById('dateInput').addEventListener('change', function (){
let inputDate = document.getElementById('dateInput').value ;
let dateConvertedToTimestamp = new Date(inputDate).getTime() ;
console.log(dateConvertedToTimestamp) ;
document.getElementById('resultTime').value = dateConvertedToTimestamp / 1000 ;
}) ;
The /1000 division convert to UNIX timestamp + I track all input change and not only when the form is submited.
HTML :
<input type='date' id='dateInput'>
<input type='hidden' id='resultTime' name='dateTimestamp'>
Don't forget date input are still not well supported, so we can easily adapt this code with classic numbers input.
You can use following code
<script type="text/javascript">
var d = new Date(parseInt($('[name="date_start"]').val()));
var n = d.getTime();
console.log(n);
</script>
