For sure, it's a javascript library. But about being a framework or not,I just think it's not a framework. Have a look on wikipedia definition of software-framework:
当然，它是一个 javascript 库。但是关于是否是一个框架，我只是认为它不是一个框架。看看维基百科对软件框架的定义：
It is a collection of software libraries providing a defined application programming interface.
它是提供定义的应用程序编程接口的软件库的集合。
And jQuery is just a single library. After that it says:
jQuery 只是一个库。之后它说：
Frameworks contain key distinguishing features that separate them from normal libraries:
- inversion of control - In a framework, unlike in libraries or normal user applications, the overall program's flow of control is not dictated by the caller, but by the framework.
框架包含将它们与普通库区分开来的关键特征：
- 控制反转 - 在框架中，与库或普通用户应用程序不同，整个程序的控制流不是由调用者决定的，而是由框架决定的。
So, I think it's not a framework.
所以，我认为这不是一个框架。

According to the angularjs web site
- a library - a collection of functions which are useful when writing web apps. Your code is in charge and it calls into the library when
it sees fit. E.g., jQuery.- frameworks - a particular implementation of a web application, where your code fills in the details. The framework is in charge and it calls into your code when it needs something app specific. E.g., durandal, ember, etc.
- 库 - 编写 Web 应用程序时有用的函数集合。您的代码负责并在
它认为合适时调用库。例如，jQuery。- 框架 - Web 应用程序的特定实现，您的代码会在其中填写详细信息。该框架负责并在需要特定于应用程序的内容时调用您的代码。例如，杜兰达尔、余烬等。

Framework and libarry are not necessarily mutually exclusive terms. Framework is typically a libarry or a collection of libraries.
框架和库不一定是相互排斥的术语。框架通常是一个库或库的集合。
Strictly speaking, jQuery is a library, but, to an extent, it does meet the definition of a software framework. Although many would argue that jQuery doesn't meet the definition of a software framework strictly enough, the fact is that no other JavaScript framework fully meets the definition of a framework either.
严格来说，jQuery 是一个库，但在某种程度上，它确实符合软件框架的定义。尽管许多人会争辩说 jQuery 不够严格地满足软件框架的定义，但事实是，没有其他 JavaScript 框架完全满足框架的定义。
One of the defining characteristics of a software framework is that its code is protected from modifications. In JavaScript, this clearly isn't the case. Any libraries or frameworks that can be called into your client-side code are modifiable, although it would be against best practices to alter them. Therefore, if it is permissible to call Bootstrap or AngularJS a framework, there is no reason why jQuery cannot be called a framework either. This linkcontains a more detailed explanation of how jQuery meets the criteria to be called a framework.
软件框架的定义特征之一是其代码不受修改。在 JavaScript 中，情况显然不是这样。任何可以调用到客户端代码中的库或框架都是可修改的，尽管更改它们将违反最佳实践。因此，如果可以将 Bootstrap 或 AngularJS 称为框架，那么 jQuery 也没有理由不能称为框架。此链接包含有关 jQuery 如何满足被称为框架的标准的更详细说明。
Perhaps the best explanation of why jQuery is more of a framework than a library is the fact that as a developer, you can chose not to use any of its framework-like functionalities. You can, for example, mix a simple jQuery statement with a standard JavaScript statement on the same line. AngularJS and Bootstrap typically don't allow you to do this. Therefore, the accurate answer whether jQuery is a framework or not is "it depends whether you chose to use it as a framework or not".
或许 jQuery 更像是一个框架而不是一个库的最好解释是，作为开发人员，您可以选择不使用其任何类似框架的功能。例如，您可以在同一行中混合使用简单的 jQuery 语句和标准的 JavaScript 语句。AngularJS 和 Bootstrap 通常不允许你这样做。因此，jQuery 是否是框架的准确答案是“这取决于您是否选择将其用作框架”。

I agree with all the answers here that jQuery itself is indeed a library, not a framework. As specified by Saeed's answer, one of the key distinguishing features is inversion of control. You could however use jQuery's functionality to create a framework of your own.
我同意这里的所有答案，即 jQuery 本身确实是一个库，而不是一个框架。正如 Saeed 的回答所指出的，关键的区别特征之一是控制反转。但是，您可以使用 jQuery 的功能来创建您自己的框架。
Examples: there are projects built on top of jQuery that are defined as frameworks: jQuery Mobile: A Touch-Optimized Web Framework, JavaScriptMVCand sammy.jsto name a few.
示例：有一些基于 jQuery 构建的项目被定义为框架：jQuery Mobile：A Touch-Optimized Web Framework、JavaScriptMVC和sammy.js等等。
There are also other libraries built on top of jQuery, like jQuery UI
还有其他基于 jQuery 构建的库，例如jQuery UI
Some of it seems like semantics when defining what a library is vs a framework, but those examples help draw the line for me.
在定义库与框架的区别时，有些似乎是语义，但这些示例有助于为我划清界限。

If we talk about Inversion of control, which almost everyone in the above thread talks about then jQuery is a FRAMEWORK.
如果我们谈论控制反转，几乎上面线程中的每个人都在谈论，那么 jQuery 就是一个框架。
It has got IOC e.g when we write the function $(document).ready{}...it is the container which calls this method and we simply put our code inside the braces. We are not the Caller of this method and hence "Inversion of Control"
例如，当我们编写函数$(document).ready{}时，它有 IOC ……它是调用此方法的容器，我们只需将代码放在大括号内。我们不是这个方法的调用者，因此是“控制反转”
This way jQuery is a FRAMEWORK.
这样 jQuery 就是一个框架。
