我正在使用下面的脚本来显示复选框的选定 ID。哪个工作得很好。当试图获得价值时，它不会返回我的价值。

<div id="selected-ID"></div>   

     function storeID() {
            var ID = $checkboxes.map(function () {
                if (this.checked) return this.id;    //this.value;
            }).get().join(',');
            $('#selected-ID').html(ID);
        }

        $(function () {
            $checkboxes = $('input:checkbox').change(storeID);
        });

问题可能是因为，我所有的复选框都在树视图中，并且树的子节点中复选框的呈现 HTML 看起来像这样。

我该如何克服这个问题，并将 ID 存储在变量中？请放一些光。

为树视图呈现的 HTML：

复选框中没有值，您应该将 value 属性添加到输入中，另一方面，输入标签没有关闭

<input type="checkbox" value="Other Services" id="ctl00_cphMain_ctlEsnSearchByServices_ctl05_Tree_Indexn0CheckBox" name="ctl00_cphMain_ctlEsnSearchByServices_ctl05_Tree_Indexn0CheckBox" />
