在JavaScript中附加两个值

上面的函数使用jQuery.val（）从一组行中的字段中获取输入值

此JS函数是if-else语句的一部分，该语句检查每行中是否有新值，并向表下方的下拉菜单项添加序号。我的问题是：如何将第一个值（描述）附加或连接到数字后的下拉菜单中？比如说,

[1]说明输入（值）

---

一切正常，我只是不知道如何将jQuery函数传递回JS或附加每个值

我不知道这个应用程序是干什么用的，但是这个

ID的

到底是干什么用的<代码>21.125-mrss-cont-none-content，

AGIM0:U:1:4:2:1:1:1:0:14

：Dauto多年前生成的代码：(

    var descriptionInput;
    var tbl = $(document.getElementById('21.125-mrss-cont-none-content'));
    tbl.find('tr').each(function () {
        $(this).find("input[name$='6#if']").keypress(function (e) {
            if (e.which == 13) {
                descriptionInput = $(this).val();
                $(this).val(descriptionInput);
                $(document.getElementById('__AGIM0:U:1:4:2:1:1::0:14')).val(descriptionInput);
            }
            console.log(descriptionInput);
        });

    });
});

var table = document.getElementById('DYN_6000-LISTSAPLMEGUI-tab');
    var t = table.rows.length;
