enter替换tab，，实现换行。。
这个代码哪里有问题吗？？
alert也出来。就是event.which = 9; 不执行啊!!!!!!
1、event.which不能修改，貌似没办法自动触发键盘事件
2、建议用keyup，用keydown的话，若一直按着按键不放会一直触发这个事件
可以用以下方法解决你的问题
document.onkeyup = function(e) {
e = e || window.event;
if (e.keyCode == 13) {
var index = Number(document.querySelector('input:focus').getAttribute('tabindex'));
document.querySelector('input[tabindex="'+ (index+1) +'"]').focus();
}
}
你的代码运行时有没有报错？你下面这段代码拷去试试呢
<!doctype html>

e = e || window.event;
if (e.keyCode == 13) {
var index = Number(document.querySelector('input:focus').getAttribute('tabindex'));
index = index == 3 ? 1 : (index + 1);
document.querySelector('input[tabindex="'+ index +'"]').focus();
}

虽然没解决你这个问题，但是我建议你的css样式不要直接写在标签上，很忌讳这样写
我把你代码拷下来，能执行。没有任何问题，你换个浏览器试试
document.onkeyup = function(e) {
e = e || window.event;
if (e.keyCode == 13) {
var index = Number(document.querySelector('input:focus').getAttribute('tabindex'));
document.querySelector('input[tabindex="'+ (index+1) +'"]').focus();
}
}
