JQuery - Get value after delimiter alternative?

I've already searched this up before and tried using both pop() and lastIndexOf but it doesn't work well on looped dropdown.

pop()

lastIndexOf

Is there any alternative to getting the value after a delimiter, one that does not remove it from the list?

Here's my code:

$(document).ready(function ()
$('#VehicleID').change(function ()
var vehdrv = ($('#VehicleID :selected').val());
var drvid = vehdrv.split("_").pop();
var vehid = vehdrv.split("_")[0];

$('#VehicleID :selected').val(vehid);
//alert($('#VehicleID :selected').val());

if (drvid > 0)
$('#DriverID').find("option").show().not("option[value*='" + drvid + "']").hide();

$("#DriverID").val(drvid);

//$("#DriverID").val(
//$("#DriverID").find("option:visible:first").val())


else
$("#DriverID").find("option").show();

$("#DriverID").val(
$("#DriverID").find("option:visible:first").val())

).trigger("change");
)


My Dropdowns from the controller:

public ActionResult ReserveInitial()

ViewBag.VehicleID = db.Vehicles.Where(item => item.IsReserved == false).Select(a => new SelectListItem

Value = a.VehicleID.ToString() + "_" + a.DriverID.ToString(),
Text = a.VehicleMake + " - " + a.PlateNumber,
);

ViewBag.DriverID = db.Drivers.Select(a => new SelectListItem

Value = a.DriverID.ToString(),
Text = a.DriverLastName + ", " + a.DriverFirstName
);


return View();



EDIT
This is how the string would look like if the VehicleID is linked to a Driver:
"14_5"

if the VehicleID is not associated with a Driver it would look like this:
"15_0"

var parts = vehdrv.split("_");
var drvid = parts[1];
var vehid = parts[0];


You can try this

var vehdrv = $('#VehicleID').val().match(/[^_]+/g);
var drvid = vehdrv[0];
var vehid = vehdrv[1];

console.log(drvid,vehid);

<input id="VehicleID" type="text" value="14_5" name="text">
