javascript - 搜索表单重复提交时添加和删除owl carousal items

Question

每当通过按 Enter 提交搜索表单时，我都会使用 AJAX 调用来获取我的轮播项目。当按下 Enter 时，我想删除以前的项目并将新项目添加到轮播中。

它一直运行良好，除非反复按下 Enter，它不会删除旧项目，只是继续添加新项目。

删除项目

function removeResult() {
    var i = 0;

    $("#result_section").slideUp(750, function () {

        $('.result_item').each(function(){

            $(".prof-carousel").trigger('remove.owl.carousel', [i++])
            .trigger('refresh.owl.carousel');

         });

    });

}

添加项目

$("#index_search_btn").click(function (e) {

    e.preventDefault();

    removeResult();

    var formData = new FormData();

    formData.append('type', search_type);

    formData.append('q', search_q);

    $.ajax({
        type: "POST",
        contentType: false,
        processData: false,
        url: "/search",
        data: formData,
        success: function (response) {

       $("#result_section").slideDown(750, function () {

           $.each(response, function (index, prof) {

               var item = '';

               item += '<div class="item carousel_ostad_item result_item">'+ 'whatever...'+'</div>';


          $('.my-carousel').owlCarousel().trigger('add.owl.carousel',[jQuery(item)]).trigger('refresh.owl.carousel');
            });

        });
    },

    error: function (xhr, ajaxOptions, thrownError) {

         alert(xhr.status + " " + thrownError);

         }

    });

});

我确实想出了一个简单的解决方案。我在按下时禁用了搜索按钮（因此无法重复提交表单）并在成功的 Ajax 回调中添加轮播项目后再次启用它。

$("#index_search_btn").click(function (e) {
e.preventDefault();
///// disable search button /////
$("#index_search_btn").attr("disabled", true);

removeResult();

var formData = new FormData();
formData.append('type', search_type);
formData.append('q', search_q);

$.ajax({
    type: "POST",
    contentType: false,
    processData: false,
    url: "/search",
    data: formData,
    success: function (response) {

        $("#result_section").slideDown(750, function () {

            $.each(response, function (index, prof) {
                var item = '';
                item += '<div class="item carousel_ostad_item result_item">'+ 'whatever...'+'</div>';
                $('.my-carousel').owlCarousel().trigger('add.owl.carousel',[jQuery(item)]).trigger('refresh.owl.carousel');

                ///// enable search button /////
                $("#index_search_btn").removeAttr("disabled");
            });

        });

    }, error: function (xhr, ajaxOptions, thrownError) {
        alert(xhr.status + " " + thrownError);
    }

});

});
