jQuery框架内部 [英] jQuery framework internals

问题描述

我想了解jquery框架的内部构造，了解代码的难度。开始使用。

感谢所有有用的输入。编辑主题，因为我添加个别评论的空间有限。
我已经写了很多基本的JavaScript代码。
我知道基本的DOM，使用事件处理程序，知道CSS基础。我已经阅读了你提到的许多话题，我熟悉它，虽然不是专家，也没有编码一些高级的话题，如闭包。这里是我使用的书籍到目前为止头部第一个javascript - 开始作为一个起始点。
我的朋友推荐的书籍，我经常使用的是Javascript - 最终指南，Javascript - 好的部分（我读过这段时间，对我来说很难）。
我的朋友刚刚推荐了Javascript忍者的秘密 - John Resig。好像好一个
我订购了你上周推荐的Javascript Design pattern book

我已经阅读了 https://developer.mozilla.org/en/JavaScript 你指出我。我会检查你指出的一些其他资源。

让我再想一想，如果我想在发布具体问题之前多做一点阅读有一个jquery。

感谢
苏珊

解决方案

要理解实际的来源将需要一定程度的JavaScript知识 - 如果您还不知道发生了什么，那么您基本上需要了解更多Javascript。

关键事项学习：

• 原型继承（ECMAScript中使用的
  继承，
  核心语言，JavaScript为
  $ b
• Lambdas（内联函数）


• 关闭（从内部函数访问的外部范围的外部变量）


• 正则表达式（用于匹配输入到jQuery的选择器字符串）


• DOM（用于与标记语言交互的DOM API）

当学习时，使用Firebug，以便您可以交互地评估您的表达，并立即看到发生了什么

如果您对某个代码段有特定问题，请问这里。我可以推荐更多高级问题的另一个资源是jQuery邮件列表或irc：//irc.freenode.net/jquery，其中jresig自己挂断并回答问题。还有其他的古代作家，像阿吉皮亚诺/保罗/ nlogax那样住在那里。

I am trying to understand the internals of how jquery framework is written and finding it hard to understand the code.

Does anyone have any suggestions regarding a good way to get started.

Thanks for all the useful input. Editing the topic since I had limited space for adding individual comments. I have written a lot of basic javascript code. I know basic DOM, have used event handlers, know CSS basics. I have read about many of the topics you have mentioned and I am familiar with it although not an expert and have not coded some of the advanced topics like closures. Here are the books I have used so far Head first javascript - good in the beginning as a starter. Books my friends have recommended and I use regularly are Javascript - The Definitive Guide, Javascript - The good parts (I read this a while ago and it was hard for me at the time). My friend just recommended Secrets of Javascript Ninja - John Resig. Seems like a good one. I ordered the Javascript Design patterns book you recommend last week

I have read the https://developer.mozilla.org/en/JavaScript you pointed me to. I will checkout some of the other resources you pointed me to.

Let me think a little more regarding if I want to do a little more reading before I post specific questions I have on jquery.

Thanks Susan

解决方案

To comprehend the actual source would require some degree of Javascript knowledge - If you don't already know what's going on then you basically need to learn more Javascript.

Key things to learn:

• Prototypal inheritance ( the inheritance used in ECMAScript, the core language on which Javascript is based upon )
• Lambdas ( inline functions )
• Closures ( outer variables from outer scope accessible from inner functions )
• Regular expressions ( used for matching the selector strings fed to jQuery )
• DOM ( The DOM API which is used to interact with markup languages )

When learning, use Firebug so you can evaluate your expressions interactively and immediately see what's going on

An excellent free resource for learning that I would recommend: http://eloquentjavascript.net/contents.html

If you're a beginner to DOM Scripting/Javascript:

• http://www.amazon.com/DOM-Scripting-Design-JavaScript-Document/dp/1590595335/ref=sr_1_19?ie=UTF8&s=books&qid=1252905196&sr=1-19

If you're intermediate level:

• http://www.amazon.com/gp/product/0596517742/ref=s9_simz_gw_s0_p14_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=0KCJ77GKHPREBFD3WAKG&pf_rd_t=101&pf_rd_p=470938631&pf_rd_i=507846

If you're past intermediate level and want to be an expert:

• http://www.amazon.com/Professional-JavaScript-Developers-Wrox-Guides/dp/0764579088
• http://www.amazon.com/Pro-JavaScript-Techniques-John-Resig/dp/1590597273/ref=sr_1_10?ie=UTF8&s=books&qid=1252905139&sr=1-10
• http://www.amazon.com/JavaScript-Design-Patterns-Recipes-Problem-Solution/dp/159059908X/ref=sr_1_16?ie=UTF8&s=books&qid=1252905196&sr=1-16

Other technical references:

• http://www.w3.org/DOM/
• http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf
• https://developer.mozilla.org/en/JavaScript

If you have specific questions about a certain code snippet just ask here. Another resource that I can recommend for more advanced questions would be the jQuery mailing list or irc://irc.freenode.net/jquery where jresig hangs out himself and comes by and answers questions. There are other guru ops who reside there like ajpiano/paulirish/nlogax.
