It's because of the jQuery version you use. https://code.jquery.com/jquery-3.1.1.slim.min.js
这是因为您使用的 jQuery 版本。 https://code.jquery.com/jquery-3.1.1.slim.min.js
slimversion of jQuery does not contain all the original jQuery functions.
slimjQuery 版本不包含所有原始 jQuery 函数。
You should use a fullversion. You can download it from here.
你应该使用一个full版本。你可以从这里下载。
It will help to better understand if you read this article from herewhere at some point in it you will find this statement and I quote:
如果您从此处阅读本文，将有助于更好地理解本文， 您会在其中找到以下声明，我引用：
Slim build
Finally, we've added something new to this release. Sometimes you don't need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests. And often it is simpler to use a combination of CSS and class manipulation for all your web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we're releasing a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code.

最后，我们在此版本中添加了一些新内容。有时您不需要 ajax，或者您更喜欢使用许多专注于 ajax 请求的独立库之一。通常，对所有 Web 动画使用 CSS 和类操作的组合更简单。除了包含 ajax 和效果模块的常规 jQuery 版本外，我们还发布了一个不包含这些模块的“瘦身”版本。总而言之，它不包括 ajax、效果和当前已弃用的代码。
