Javascript还是Jquery？我应该学习哪一个？ [英] Javascript or Jquery? Which one should i learn ?

问题描述

好的，我是asp.net开发人员（初学者）我不知道两者中的任何一个。我知道Jquery是一个用javascript构建的框架，但我想知道花时间学习Jquery而不学习javascript是否合理？我不想浪费时间学习一些不值得的东西。我还想知道我应该花多少天学习它们？ 15天是否足以学习Jquery或Javascript？在使用异步调用创建动态网站时足够使用它们。

解决方案

我想说，拥有相当一般的编程经验，15天就足以学习它了你能写出合理代码的程度。特别是它对jQuery来说是正确的，因为它和所有库一样，不应该学习（对于库来说是什么？:-)）;相反，你只需要了解这个想法，只知道在哪里寻找参考信息。



话虽如此，我严重怀疑你个人能做什么那。我可以解释原因，这是你的问题：



你没注意到你无法在JavaScript和jQuery之间做出选择，因为jQuery只是一个JavaScript库，没有JavaScript就无法使用。我不能相信在发布问题之前没有注意到这些高度可见的事情的人。你是如何阅读和理解文档的，具有这样的阅读技巧？



此外，JavaScript根本不是一个选项，因为这是客户的唯一标准 - 侧脚本（也有VB脚本，但不能认真考虑;我们正在讨论标准）。所以，唯一的选择是学习或不学习jQuery。我会说，自己在jQuery中很好地实现很多东西会很愚蠢。如果不学习它，你就不会节省时间，你会浪费额外的时间做很多已经为你做过的重要事情。

Ok, i am asp.net developer (beginner) i do not know either of the two. I do know Jquery is a framework built from javascript but i want to know if it would be reasonable to spend time learning Jquery without learning javascript? I would not like to waste time learning something which is not worth it. I would also like to know how many days should i spend learning them? Would 15 days be enough to learn Jquery or Javascript? Enough to use them while making dynamic websites with asynchronous calls.

解决方案

I would say that, having fairly general programming experience, 15 days would be quite enough to learn it to the degree when you are able to write sensible code. Especially it it true for jQuery, because it, like all library, should not be "learned" (what is is, for a library? :-)); instead, you just need to understand the idea and only know where to look for the reference information.

Having said that, I have a serious doubt that you personally can do that. I can explain why, this is in your question:

You failed to notice that you cannot make a choice between JavaScript and jQuery, simply because jQuery is only a JavaScript library, it cannot be used without JavaScript. I cannot trust person who fails to notice such highly visible things before posting a question. How are you going to read and understand documentation, with such reading skills?

Also, JavaScript is not an option at all, because this is the only standard for client-side scripting (there is also VB scripting, but it cannot be seriously considered; we are talking about standards). So, the only option would be to learn or no not to learn jQuery. I would say, doing many things so nicely implemented in jQuery by yourself would be just silly. By not learning it, you are not saving time, you would waste extra time for doing many important things which are already done for you.
