如何获取jQuery的选定值

Question

我有一个带复选框的多选下拉菜单。我想在变量和警报弹出窗口中获取选定的值。在下拉列表中，每当我选中这些复选框时，我都会带有一些带有复选框的值，我希望这些选定的值位于变量中。请让我知道如何实现这一目标。找到下面的代码。

 <script> 
    var colors = [
        { Name: "jQuery/HTML5/ASP.NET MVC Controls" },
        { Name: "ASP.NET Controls" },
        { Name: "Windows Forms Controls" },
        { Name: "WPF Controls" },
        { Name: "Android Native mobile controls" },
        { Name: "iOS Controls" },
        { Name: "SharePlus" },
        { Name: "ReportPlus" },
        { Name: "Indigo Studio" }
    ];


    $(function () {

        $("#singleSelectCombo").igCombo({
            width: 300,
            dataSource: colors,
            textKey: "Name",
            valueKey: "Name",
            dropDownOnFocus: true,
            dropDownOrientation: "bottom"
        });

        $("#multiSelectCombo").igCombo({
            width: 300,
            dataSource: colors,
            textKey: "Name",
            valueKey: "Name",
            multiSelection: {
                enabled: true
            },

            dropDownOrientation: "bottom"

        });

        $("#checkboxSelectCombo").igCombo({
            width: 300,
            dataSource: colors,
            textKey: "Name",
            valueKey: "Name",
            multiSelection: {
                enabled: true,
                showCheckboxes: true,

            },
            dropDownOrientation: "bottom"
        }); 
    });

    $(document).ready(function() {
    $(".btn").click(function() {
        var colors = [];
        $.each($("input[Name='colors']:checked"), function() {
            colors.push($(this).val());
        }); 
    });
});  
</script>
