jquery redirect to page

Momentarily I manage to redirect to another page with parameter using

and

public IActionResult OnPostForm1Post()
        {
            return RedirectToPage("/Test");
        }
        public IActionResult OnPostForm2Post()
        {
            return RedirectToPage("/Index");
        }
        public IActionResult OnPostForm3Post()
        {
            return RedirectToPage("/IndexMain");
        }

and

$(function () {
            $("#RepType").on("change", function () {
                var data = $("#RepType :selected").text();
                if (data == "Unsafe Act") {
                    $('#Form1').submit();
                }
                else if (data == "Unsafe Condition") {
                    $('#Form2').submit();
                }
                else if (data == "Near-Miss") {
                    $('#Form3').submit();
                }
            });
        });

How can I do it directly from jquery?
