使用javascript设置失效日期

Question

I have a form with inputs and I want on submit button click to take the current time and add 10 hours to update the table cell expdate I have this function but doesn't work

<script>
$("#registerButton").click(function() {
    var signintime =$("#scantime").val();
    var id = $("#id").val();
    var expdate = ($("#scantime").val() +36000));
       $.ajax({
            url: "updatescan.php",
            method: "POST",
       data: {signintime:signintime,expdate:expdate,id:id} , 
dataType:"text",   
            success: function(data)
                        {                   
                        }
        });
    });
</script>

The field with the id #scantime has a real time clock as a value

I have also tried this but it doesn't work with javascript

$expdate = date('Y-m-d H:i:s', time()+36000);
var expdate = date('Y-m-d H:i:s', time()+36000);`

i've managed to get current time and insert to db with this

var x = new Date();
var x1=x.getFullYear() + "-" + x.getMonth() + "-" + x.getDate();
x1 = x1 + "  " + x.getHours( )+ ":" + x.getMinutes() + ":" + x.getSeconds();
var expdate=x1;

but how i add 10 hours to this ? Thank you

Answer 1

Please pay attention that getMonth is month-1

So if you need dates as a string you should use getMonth()+1

// php
echo strtotime('now +10 hours');

// js 
var d = new Date();
d.setHours(d.getHours()+10);

Answer 2

var d = new Date(); d.setHours(10); The result of d will be:
