怎么在JS中设置账号框按回车键光标直接移动到密码输入框

Question

获取元素，然后判断键盘是否按下的是回车，然后呢？该怎么办？下边代码根本没有用

<p>账号：<input type="text" autofocus/></p>
<p>密码：<input type="password" ></p>
<p><button>登录</button></p>

<script>
    var plist=document.querySelectorAll('p');
    plist[0].onkeydown=function(){
        if(event.keyCode==13){
            this.childNodes[1].removeAttribute('autofocus');

            this.nextSibling.nextSibling.childNodes[1].setAttribute('autofocus',true);
        }
    }
</script>

    var plist = document.querySelectorAll('p');
    plist[0].onkeydown = function (e) {

        if (e.keyCode == 13) {
            plist[1].querySelector('input').focus();
            return false;;//阻止表单提交
        }
    }
