jQuery如何使Enter（Return）作为Tab键通过输入文本字段，但最终触发提交按钮

我已经阻止了Enter（返回）键，实际上它在Tab键中进行了转换。所以当在输入文本字段内按压时，它作为Tab键。这是好的，但是我需要它在最后一个字段中按下时触发提交按钮，下面是Enter键突变的代码：

I've blocked Enter (return) key, actually, transformed it in Tab key. So when pressed inside input text fields it acts as Tab key. This is good, but I need it to trigger the submit button when pressed in the last field, below is the code for the Enter key mutation:

            $('input').keydown(function(event) {
                if(event.which == 13) {
                    event.preventDefault();
                    $(this).nextAll('input:first').focus();
                }
            });

表单代码是输入类型=文本而在结尾的一个按钮type =submit

其实代码是这个，从 jquery：在特定部分中输入Tab触发器。但我不知道今天昨天工作的原因是不起作用的：

And the form code is a sequence of input type="text" and a button type="submit" at the end Actually the code is this one, taken from jquery: Enter to Tab trigger in specific parts. But I don't know why it was working yesterday today is not working:

$(':text').keydown(function(e) {
    if(e.keyCode == 13 && $(this).attr('type') != 'submit') {
        e.preventDefault();
        $(this).nextAll('input:first').focus();
    }
});
