Uncaught TypeError: $.post is not a function
提问by Donnie Ashok
I am getting this error in Console:
我在控制台中收到此错误：
Uncaught TypeError: $.post is not a function
未捕获的类型错误：$.post 不是函数
for this piece of code:
对于这段代码：
<script type="text/javascript">
$('#cl_submit').click(function() { //#cl_submit is a button
$('#cl_stage1msg').html('Processing...');
$.post("process/cookie.php", $("#cl").serialize(), function(response) { //#cl is a form
$('#cl_stage1msg').html(response);
});
return false;
});
</script> <!-- popup included -->
I just couldn't find anything wrong in this. Why is this not working, any clues?
我只是找不到任何错误。为什么这不起作用，任何线索？
However, $('#cl_stage1msg').html('Processing...');is working fine.
但是，$('#cl_stage1msg').html('Processing...');工作正常。
Seems like only the post function is not getting recognised.
似乎只有 post 功能没有得到认可。

You are using the slim versionof jQuery, which doesn't have AJAX(in your case the $.post()function).
您正在使用jQuery的精简版，它没有 AJAX（在您的情况下是$.post()函数）。
Use the non-slim build, available here http://jquery.com/download/, such as:
使用non-slim build，可在http://jquery.com/download/ 处获得，例如：
https://code.jquery.com/jquery-3.3.1.min.js
https://code.jquery.com/jquery-3.3.1.min.js
From jQuery 3.0 release post:
Slim build
[...] Sometimes you don't need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests.[...] Along with the regular version of jQuery that includes the ajax and effects modules, we're releasing a “slim” version [...], it excludes ajax, effects, and currently deprecated code.

[...] 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。[...] 连同包含 ajax 和效果模块的 jQuery 常规版本，我们正在发布一个“slim”版本 [...]，它不包括 ajax、效果和当前已弃用的代码。

If you use jquery slim version then this problem will occur. use minified or uncompressed version of jquery js file
如果使用 jquery slim 版本，则会出现此问题。使用缩小或未压缩版本的 jquery js 文件
