javascript - 通过 javascript 使用 Enter 键添加新行

Question

我有以下代码:

$(document).on('keypress', ".addNewRow", function(e){
    var keyCode = e.which ? e.which : e.keyCode;
    if(keyCode == 9 ) addNewRow();
});

按“Tab”后，此代码将执行 addNewRow (添加表数据)。这很完美。我想改变它以使其与“Enter”一起使用，所以我修改如下:

$(document).on('keypress', ".addNewRow", function(e){
    var keyCode = e.which ? e.which : e.keyCode;
    if(keyCode == 9,13 ) addNewRow();
});

由于某些奇怪的原因，这无法按预期工作。我是否缺少一种不同的方法来做到这一点？ *用头撞墙

编辑:也尝试过这个:

$(document).on('keypress', ".addNewRow", function(e){
    var keyCode = e.which ? e.which : e.keyCode;
    if(keyCode == 9||13 ) addNewRow();
});

表单代码(防止输入时提交):

<script type="text/javascript">
function tabE(obj, e) {
  var e = (typeof event != 'undefined') ? window.event : e; // IE : Moz

  var self = $(obj),
    form = self.parents('form:eq(0)'),
    focusable, next;

  if (e.keyCode == 13) {
    focusable = form.find('input,a,select,button,textarea').filter(':visible');
    next = focusable.eq(focusable.index(obj) + 1);
    if (!next.length) {
      next = focusable.first();
    }
    next.focus();
    return false;
  }
}
</script>
<!-- Prevent Enter from Submitting Form -->
<script>
                    $(document).on("keydown", "input", function(e) {
                    if (e.which==13) e.preventDefault();
                    });
                    </script>
    <!-- Begin page content -->

正确的或语句:

if (keyCode == 9 || keyCode  == 13)
