检查此页面： http:// jquery14.com/day-01/jquery-14 （来自 web.archive.org 的缓存版本）
底部有一个重大更改列表。如果您遇到问题，它会给您一个想法。
还有一个 插件 使 jQuery 1.4 与 1.3 兼容。
Check this page: http://jquery14.com/day-01/jquery-14 (cached version from web.archive.org)
On the bottom there's a list of breaking changes. It will give you an idea if there are issues for you.
There's also a plugin which makes jQuery 1.4 compatible with 1.3.
你应该没问题，但这里有一个潜在问题列表：
http://jquery14.com/day- 01#向后
you should be fine but there are a list of potential issues here:
http://jquery14.com/day-01#backwards
最好的办法就是尝试一下看看。 jQuery14.com 有一个向后兼容性列表，以及您可以使用的 1.3 兼容插件以减轻打击。
Best bet is to try it and see. jQuery14.com has a backward compatibility list, as well as a 1.3-compat plugin you can use to soften the blow.
前几天我也做了同样的事情，没有任何问题。一件有趣的事情是，该网站声称 1.4 不再默认
$()为$(document).ready- 然而我确实有这样的代码并且它工作正常。 ..I've done the same thing the other day and had no issues. One interestng thing is that the site claims that 1.4 no longer defaults
$()to$(document).ready- I do however have such code and it is working fine...
