选择器返回项目两次

Question

我有以下代码

 var cval2 = $(':input[value^="ltrXYAxis"]:checked').map(function () {
                return this.value.replace('ltrXYAxis', '');
            }).get().join('@@');

它返回两次检查项目

像

  

@@与firstItem @@ seconditem @@与firstItem seconditem

我希望输出像他的

  

@@与firstItem @@ seconditem

使用下面的内容

 var cval2 = $(':#ltrXYAxis option:selected:not(:disabled)').map(function () {
                return this.value.replace('ltrXYAxis', '');
            }).get().join('@@');
