You are using the **slim version** of jQuery, which **doesn&#39;t include the Ajax methods** (in your case `$.post()`).

Use the **non-slim build**, available here http://jquery.com/download/, such as:

`https://code.jquery.com/jquery-3.5.1.min.js`

------

From [jQuery 3.0 release post](https://blog.jquery.com/2016/06/09/jquery-3-0-final-released/):

&gt; Slim build
&gt; 
&gt; [...] Sometimes you
&gt; don’t need ajax, or you prefer to use one of the many standalone
&gt; libraries that focus on ajax requests.[...] Along with the regular version of jQuery that includes the
&gt; ajax and effects modules, we’re releasing a “slim” version [...], it excludes ajax, effects, and
&gt; currently deprecated code.

If you use jquery slim version then this problem will occur. use minified or uncompressed version of jquery js file  

The Python built-in function `any(iterable)` can help to quickly check if any `bool(element)` is `True` in a iterable type.

    &gt;&gt;&gt; l = [None, False, 0]
    &gt;&gt;&gt; any(l)
    False
    &gt;&gt;&gt; l = [None, 1, 0]
    &gt;&gt;&gt; any(l)
    True

But is there an elegant way or function in Python that could achieve the opposite effect of `any(iterable)`? That is, if any `bool(element) is False` then return `True`, like the following example:

    &gt;&gt;&gt; l = [True, False, True]
    &gt;&gt;&gt; any_false(l)
    &gt;&gt;&gt; True


Opposite of any() function

Using `java -XX:+PrintFlagsFinal` I found the `TieredCompilation` flag, and I read about it a bit online.

Yet, I still don&#39;t know _exactly_ what happens when setting it to `false`.

I know that the compilation system supports 5 execution levels, basically splitted into interpreter, C1 and C2:

 *  level 0 - interpreter
 *  level 1 - C1 with full optimization (no profiling)
 *  level 2 - C1 with invocation and backedge counters
 *  level 3 - C1 with full profiling (level 2 + MDO)
 *  level 4 - C2

Two questions:

(1) By setting `-XX:-TieredCompilation`, are some of this levels just disabled? If yes, which?

(2) Is there some flag to decide whether to disable C1 or C2, or to not compile at all?

What exactly does -XX:-TieredCompilation do?

I am getting this error in Console:

&gt;Uncaught TypeError: $.post is not a function

for this piece of code:

&lt;script type=&quot;text/javascript&quot; src=&quot;https://code.jquery.com/jquery-3.1.0.slim.min.js&quot;&gt;&lt;/script&gt;
	&lt;script type=&quot;text/javascript&quot;&gt;

				$(&#39;#cl_stage1msg&#39;).html(response);
			});
			return false;

	&lt;/script&gt; &lt;!-- popup included --&gt;

I just couldn&#39;t find anything wrong in this. Why is this not working, any clues?

However, `$(&#39;#cl_stage1msg&#39;).html(&#39;Processing...&#39;);` is working fine.

Seems like only the post function is not getting recognised.

I have an action making a `POST` request to the server in order to update a user&#39;s password, but I&#39;m unable to handle the error in the chained catch block.



    return axios({
      method: &#39;post&#39;,
      data: {
        password: currentPassword,
        new_password: newPassword
      },
      url: `path/to/endpoint`
    })
    .then(response =&gt; {
      dispatch(PasswordUpdateSuccess(response))
    })
    .catch(error =&gt; {
      console.log(&#39;ERROR&#39;, error)
      switch (error.type) {
        case &#39;password_invalid&#39;:

Have I unknowingly made a mistake somewhere? Because I&#39;m handling other errors from different request fine, but can&#39;t seem to work this one out.

Let&#39;s say I have two arrays,

    var PlayerOne = [&#39;B&#39;, &#39;C&#39;, &#39;A&#39;, &#39;D&#39;];
    var PlayerTwo = [&#39;D&#39;, &#39;C&#39;];

What is the best way to check if arrayTwo is subset of arrayOne using javascript?

The reason: I was trying to sort out the basic logic for a game Tic tac toe, and got stuck in the middle. Here&#39;s my code anyway... Thanks heaps!

    var TicTacToe = {
    
    
      PlayerOne: [&#39;D&#39;,&#39;A&#39;, &#39;B&#39;, &#39;C&#39;],
      PlayerTwo: [],
    
      WinOptions: {
          WinOne: [&#39;A&#39;, &#39;B&#39;, &#39;C&#39;],
          WinTwo: [&#39;A&#39;, &#39;D&#39;, &#39;G&#39;],

          WinSix: [&#39;D&#39;, &#39;E&#39;, &#39;F&#39;],

          WinEight: [&#39;C&#39;, &#39;E&#39;, &#39;G&#39;]
      },
    
      WinTicTacToe: function(){
    
        var WinOptions = this.WinOptions;
        var PlayerOne = this.PlayerOne;
        var PlayerTwo = this.PlayerTwo;
        var Win = [];
    
        for (var key in WinOptions) {
          var EachWinOptions = WinOptions[key];
    
            for (var i = 0; i &lt; EachWinOptions.length; i++) {
              if (PlayerOne.includes(EachWinOptions[i])) {
                (got stuck here...)
              }

            // 
            // if (PlayerOne === WinOptions[key].sort().join()) {
            //   console.log(&quot;PlayerOne has Won!&quot;);
            // }

            //   console.log(&quot;PlayerTwo has Won!&quot;);

I have been studying Node.js recently and came across some material on writing simple Node.js based servers. For example, the following.

    var express = require(&quot;express&quot;),
    http = require(&quot;http&quot;), app;

    // Create our Express-powered HTTP server
    // and have it listen on port 3000
    app = express();
    http.createServer(app).listen(3000);

    // set up our routes
    app.get(&quot;/hello&quot;, function (req, res) {
        res.send(&quot;Hello World!&quot;);
    });

    app.get(&quot;/goodbye&quot;, function (req, res) {
        res.send(&quot;Goodbye World!&quot;);
    });


Now, although I seem to understand what&#39;s going on in the code, I am slightly confused by the terminology. When I hear the term server, I think about stuff like Apache or Nginx. I am used to thinking about them as being like a container that can hold my web applications. How does Node.js server differ from Nginx/Apache server? Isn&#39;t it true that a Node.js based server (i.e. code) can still be placed within something like Nginx to run? So why are both called &quot;servers&quot;?

I&#39;ve created a new Foundation 5 project through bash, with `foundation new my-project`. When I open the index.html file in Chrome an `Uncaught TypeError: a.indexOf is not a function` error is shown in the console, originating in `jquery.min.js:4`.

I created the project following the steps on the foundation site, but I can&#39;t seem to get rid of this error. Foundation and jQuery look like they are included and linked up correctly in the index.html file, and the linked app.js file is including `$(document).foundation();`

Does anyone know what is causing this error? and what a solution might be?

When using `window.onbeforeunload` (or `$(window).on(&quot;beforeonload&quot;)`), is it possible to display a custom message in that popup?

Maybe a small trick that works on major browsers?

By looking at existing answers I have the feeling this was possible in the past using things like `confirm` or `alert` or `event.returnValue`, but now it seems they are not working anymore.

So, how to display a custom message in the beforeunload popup? Is that even/still possible?

I am using hammer for dragging and it is getting choppy when loading other stuff, as this warning message is telling me.

&gt; main thread being busy. Consider marking event handler as &#39;passive&#39; to
&gt; make the page more responsive.

So I tried to add &#39;passive&#39; to the listener like so

    Hammer(element[0]).on(&quot;touchstart&quot;, function(ev) {

      passive: true
    });

but I&#39;m still getting this warning.

Is there any way to disable `strict MIME type checking ` in Chrome.

Actually I&#39;m making a JSONP request on cross domain. Its working fine on Firefox but, while using chrome its giving some error in console.

&gt;Refused to execute script from &#39;https://example.com&#39; because its MIME type (&#39;text/plain&#39;) is not executable, and strict MIME type checking is enabled.

Its working perfectly in Mozilla.. Issue is arising in chrome only

Here are the response Headers of the request..

    Cache-Control:no-cache, no-store
    Connection:Keep-Alive
    Content-Length:29303
    Content-Type:text/plain;charset=ISO-8859-1

    Strict-Transport-Security: max-age=31536000; includeSubDomains
    X-Content-Type-Options:nosniff
