jQuery和Prototype目前有什么区别？ [英] What are the current differences between jQuery and Prototype?

问题描述

最近几个月我一直在构建一个Ruby on Rails网站，我只使用了少量内置的JavaScript函数。但是我将在未来几周和几个月内进行更多的JavaScript开发，我正在讨论要使用哪个JavaScript框架。

I've been building a Ruby on Rails site in recent months and I've only used a small amount of built in JavaScript functions. However I will be doing much more JavaScript development in the coming weeks and months and I am debating on which JavaScript framework to go with.

一方面jQuery似乎是更受欢迎的一个，但是再次Prototype已经内置到Rails中。几年前我还在线阅读了一些文章，讨论了jQuery在某些方面是如何更简洁，但在其他方面却很邋and，并提出了各种其他意见。

On the one hand jQuery seems to be the more popular one, but then again Prototype is already built into Rails. I've also read a bunch of articles online from a few years ago talking about how jQuery is more concise at some things but sloppy on others, and giving various other opinions.

所以我的问题是那些同时使用（最近最近）的人：

So my questions are to the people who have used both (preferably recently):

• 有什么区别从纯JavaScript和Ruby on Rails角度使用Prototype和jQuery？


• 他们之间是否存在显着差异，或者他们现在在功能和代码编写方面彼此非常接近？


• 根据必须重新考虑的事项转换成本和必须重写的代码？

谢谢

上一次讨论

如果不是全部问题，那么很多已经讨论过了。请参阅 搜索 或：

Much, if not all of your question has been discussed already. See the search or:

切换自原型到JQuery

我正在从Protoype转换到JQuery，主要是出于性能原因（我已经看到了太多基于Prototype的基准测试最后来到JQuery，MooTools和Dojo。）我认为转换成本并不可怕，因为大多数基本概念（选择，效果，Ajax）非常相似。但是，每一行Prototype代码都必须仔细重写 - 特别是因为许多辅助函数和结构（ $ $$ ）看起来欺骗性地相似。

I'm in the process of switching from Protoype to JQuery, mainly for reasons of performance (I have seen too many benchmarks with Prototype always coming in last to JQuery, MooTools and Dojo.) I would say switching cost is not horrible, because most basic concepts (Selection, Effects, Ajax) are very similar. However, every line of Prototype code has to be carefully rewritten - carefully especially because many helper functions and constructs ($ $$) look deceivingly similar.

如果您的代码包含许多可能在Jquery中可用的复杂链式构造，但功能不同，迁移可能会变得非常麻烦。如果你只使用它来快速选择$（）元素，效果和一些Ajax，那就不用了。

If your code contains many complex chained constructs that may be available in Jquery as well, but function differently, migration can become a very cumbersome task. If you use it only for quick $() element selection, effects and a bit of Ajax, not so much.

无论哪种方式，都要为一个强烈的学习阶段做好准备。 JQuery构造虽然小而且聪明，但是阅读恕我直言是很糟糕的（与一个原生Javascript块相比看起来很糟糕，但这是一个不同的讨论）。如果您来自不同的框架或本机Javascript，那么熟悉语法和原则肯定需要时间。

Either way, be prepared for a phase of intense learning. JQuery constructs are small and smart, but are terrible to read IMHO (and look god-awful compared to a block of native Javascript, but that's a different discussion). It definitely takes time to get familiar with the syntax and principles if you're coming from a different framework, or native Javascript.
