克隆的 Select2 在 Asp.Net 中不起作用

Question

我尝试了很多资源：

Cloned Select2 is not responding

解释：

View page is build up using Razor. i'm trying to clone the row using JQuery, first one is working properly and newly created( dynamic) is not opening (freezed). Image: image link

查看代码：

                        <div id="ROW_0" class="template">
                            <hr />
                            <div class="row">
                                <div class="col-md-6">
                                    <div class="form-group">
                                        <label>Credit Account</label>
                                        @Html.DropDownListFor(model => model.AccountsId, new SelectList(Model.Accountss, "Id", "Name"), "-- select account --", new { @class = "form-control select required select2insidemodal", @id = "creditAccount" })
                                    </div>
                                </div>
                                <div class="col-md-6">
                                    <div class="form-group">
                                        <label>Amount</label>
                                        @Html.EditorFor(model => model.Credit, new { htmlAttributes = new { @class = "form-control", @type = "text", @id = "credit" } })
                                    </div>
                                    <span id="error-@Html.NameFor(vm => vm.Credit)" class="dN cR"></span>

                                </div>
                            </div>
                        </div>

脚本：

//button for adding row 
$(document).ready(function () {

  $(document).on('click', "#addMore",function (e) {
             addNewRow();
         });
         
        function addNewRow() {
            var div = $(".template").clone().html();

            //find all select2 and destroy them   
           $(div).find(".select2").each(function (index) {
                if ($(this).data('select2')) {
                    $(this).select2('destroy');
                }
            });


           $("#dynamicBlock").prepend(div); //adding cloned data to new div '#dynamicBlock'.

帮帮我。

您似乎没有在将新 select 附加到页面后对其进行初始化。

您需要将新脚本附加到页面（和运行它），以设置 select，否则它们将停滞不前。

var initScript = '$(".select2insidemodal").select2();';

$('<script>' + initScript + '</' + 'script>').appendTo(document.body);

如果您要克隆多个 select，那么我想您可以只在最后一次添加初始化脚本，因为它应该初始化每个克隆的 select.
