I have a DateTime as this is C#:
public DateTime ShipmentDate { get; set; }
I show the value in textbox
This is in cshml:
<div class="col-sm-2">
<label for="ShipmentDate">Shipment Date:</label><br />
<input type="text" name="ShipmentDate" id="ShipmentDate" disabled="disabled" />
</div>
And this is in JavaScript:
$('#ShipmentDate').val($.formatDate(PurchaseOrder.ShipmentDate));
When ShipmentDate is nullable like this:
public DateTime? ShipmentDate { get; set; }
and the date is empty, it shows some random Date as 1960/12/31 in textbox
When ShipmentDate is not nullable shows the date as: 1/1/0001 in textbox
In both in C# date is Null and when I do console.log shows null in the console. How I can show empty String in textbox when ShipmentDate in Null.
Since PurchaseOrder.ShipmentDate can be null, it is worth handling this case so that the $.formatDate(null) doesn't return an invalid date as noticed.
In Javascript, if a variable is null then is treated as a falsy value. So it only executes the formatDate if the ship is not one of the many falsy values, including null.
const ship = PurchaseOrder.ShipmentDate;
$('#ShipmentDate').val(ship ? $.formatDate(ship) : "");
