select2下拉菜单转到Enter Key按下的下一个下拉菜单

Question

我使用select2在下拉列表中启用搜索字段。但是我想在输入密钥后移动到下一个下拉字段。

＆＃13;

＆＃13;

$(document).ready(function() {
        $(".js-example-basic-single").select2();
    });
    
    $(document).on("click", ".select2-container", function ()
{
    setTimeout("dropscroll()", 1)
}),
    $("#dob_day").select2().on("select2:close", function (e)
        {
            $("#dob_month").focus()
        }
    ),

    $("body").on("#container", ".select2", function ()
    {
        $("#dob_day").select2("open")
    });

＆＃13;

.dob_m{
    height: 34px;!important;
    width: 110px;!important;
}
.dob_d{
    height:34px;!important;
    width: 65px;!important;

}
.dob_y{
    height:34px;!important;
    width: 85px;!important;
}

我想在使用enter和tab键选择每个下拉列表后转到下一个。我只能每天搬家。但是如何每月添加。
