Bootstrap 5 Dropdowns: Get selected dropdown item value in the dropdown button

Question

I have a simple issue with my dropdown button while I'm trying to get the selected dropdown item to the dropdown button value.

The Flag Icon and Text should be changed dynamically I made some examples but as I see it's not working as I expected.

The only issue that I have is the flag icon not changed dynamically

HTML:

<div class="dropdown">
    <button class="btn btn-primary btn-lg dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false"><span class="flag-icon flag-icon-us me-1"></span> <span>English</span></button>
    <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
        <li>
            <a class="dropdown-item active" href="#"><span class="flag-icon flag-icon-us me-1"></span> <span>English</span></a>
        </li>
        <li>
            <a class="dropdown-item" href="#"><span class="flag-icon flag-icon-fr me-1"></span> <span>French</span></a>
        </li>
        <li>
            <a class="dropdown-item" href="#"><span class="flag-icon flag-icon-es me-1"></span> <span>Spanich</span></a>
        </li>
        <li>
            <a class="dropdown-item" href="#"><span class="flag-icon flag-icon-sa me-1"></span> <span>Arabic</span></a>
        </li>
    </ul>
</div>

jQuery

if ($(".dropdown").length) {
    $(document).on("click", ".dropdown-menu .dropdown-item", function (e) {
        e.preventDefault();
        if (!$(this).hasClass("active")) {
            var swalWithBootstrapButtons = Swal.mixin({
                customClass: {
                    confirmButton: "btn btn-primary",
                    cancelButton: "btn btn-danger me-3",
                },
                buttonsStyling: false,
            });
            swalWithBootstrapButtons
                .fire({
                    title: "Are you sure?",
                    text: "Do you really want to change your current language!",
                    icon: "warning",
                    confirmButtonText: "<i class='fas fa-check-circle me-1'></i> Yes, I am!",
                    cancelButtonText: "<i class='fas fa-times-circle me-1'></i> No, I'm Not",
                    showCancelButton: true,
                    reverseButtons: true,
                    focusConfirm: true,
                })
                .then((result) => {
                    if (result.isConfirmed) {
                        if (!$(this).hasClass("active")) {
                            $(".dropdown-menu .dropdown-item").removeClass("active");
                            $(this).addClass("active");
                            $(this)
                                .parents(".dropdown")
                                .find(".btn")
                                .html("<span class='flag-icon flag-icon-us me-1'></span>" + $(this).text());
                        }
                        Swal.fire({
                            icon: "success",
                            title: "Amazing!",
                            text: "Your current language has been changed successfully.",
                            showConfirmButton: false,
                            timer: 1500,
                        });
                    }
                });
        }
    });
}

Answer 1

you need to replace .html("<span class='flag-icon flag-icon-us me-1'></span>" + $(this).text()); with .html($(this).html()); , it will give you the desired output

Answer 2

Please check this, I have just updated the code to get class of clicked option and added to the span in HTML

 if ($(".dropdown").length) { $(document).on("click", ".dropdown-menu .dropdown-item", function (e) { e.preventDefault(); var cloneflagicon = $(this).find('span.flag-icon').attr('class'); if (!$(this).hasClass("active")) { var swalWithBootstrapButtons = Swal.mixin({ customClass: { confirmButton: "btn btn-primary", cancelButton: "btn btn-danger me-3", }, buttonsStyling: false, }); swalWithBootstrapButtons .fire({ title: "Are you sure?", text: "Do you really want to change your current language!", icon: "warning", confirmButtonText: "<i class='fas fa-check-circle me-1'></i> Yes, I am!", cancelButtonText: "<i class='fas fa-times-circle me-1'></i> No, I'm Not", showCancelButton: true, reverseButtons: true, focusConfirm: true, }) .then((result) => { if (result.isConfirmed) { if (!$(this).hasClass("active")) { $(".dropdown-menu .dropdown-item").removeClass("active"); $(this).addClass("active"); $(this) .parents(".dropdown") .find(".btn") .html("<span class='"+cloneflagicon+"'></span>" + $(this).text()); } Swal.fire({ icon: "success", title: "Amazing!", text: "Your current language has been changed successfully.", showConfirmButton: false, timer: 1500, }); } }); } }); }
