Hi Team

I am trying to make a logic around, when my unchecked-box is used must clear the datepicker. Now its not doing that at all and need some help around it, please team.

What I have tried:

@using (Html.BeginForm("Modules", "Home", FormMethod.Post))
                                   {
                                       @Html.CheckBoxFor(model => model.Lockuntil, new { @class = "rb", data_toggle = "hide-element", data_target = "#datepicker17" })
                                       @Html.LabelFor(model => model.Lockuntil, new { @class = "form-check-label" })
                                       @Html.TextBoxFor(model => model.DateColumn, new { id = "datepicker" })
                                   }

<!--Jquery for checking datepicker-->
                    <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
                    <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
                    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
                    <script type="text/javascript">
                        $(function () {
                            var toggleHideElement = function (chk) {
                                var target = $(chk.getAttribute("data-target"));
                                if (chk.checked) {
                                    target.removeClass("d-none").attr("aria-hidden", "false");
                                }
                                else {
                                    target.addClass("d-none").attr("aria-hidden", "true");
                                }
                            };

                            // Change the state of the target element when the box is checked / unchecked:
                            $(document).on("change", "input:checkbox[data-toggle='hide-element']", function () { toggleHideElement(this); });

                            // Set the initial state of the target element:
                            $("input:checkbox[data-toggle='hide-element']").each(function () { toggleHideElement(this); });
                        });

                        // Another function call for DatePicker.
                        $(function () {
                            $("#datepicker").datepicker();
                        });
                    </script>

Hide the date picker when the box is not checked:

JavaScript

var toggleHideElement = function (chk, fromLoad) {
    var target = $(chk.getAttribute("data-target"));
    if (chk.checked) {
        target.removeClass("d-none").attr("aria-hidden", "false");
        if (!fromLoad) { target.focus().datepicker("show"); }
    }
    else {
        target.addClass("d-none").attr("aria-hidden", "true");
        if (!fromLoad) { target.datepicker("hide"); }
    }
};


// Change the state of the target element when the box is checked / unchecked:
$(document).on("change", "input:checkbox[data-toggle='hide-element']", function () { toggleHideElement(this, false); });

// Set the initial state of the target element:
$("input:checkbox[data-toggle='hide-element']").each(function () { toggleHideElement(this, true); });
