There are some classic examples, such as "_I'm querying the database and showing the info in HTML and it doesn't work_". If the problem is in the database (maybe in the query, or in how you're processing the results), the HTML part is irrelevant: just print the data to show how wrong it is, and how t... (more) |

I don't get it, `javax.mail` doesn't use Bouncy Castle (BC). Perhaps the `mdnCreator.createMDNData()` method creates an object that uses BC to generate mime data? As you didn't provide the code for `createMDNData`, I've made a simple test:

I've made a test in Python 3, and python-dotenv worked fine:
```python

from dotenv import load_dotenv
load_dotenv()
# both os.environ and os.getenv worked
print(os.environ["MY_ID"], os.environ["TOKEN"])

Instead of `form id="#prcf_form"`, it should be `form id="prcf_form"`. The `#` is used only in the selector, it indicates that you're searching for an id. But in the HTML, there should be no `#` (more) |

The answer below is basically doing what I suggested (using `fetch` and `FormData` to send the data via POST).
As you didn't say if it worked, I assumed it didn't work and therefore there might be some missing details (because based on what I could understand, that code should work) (more) |

In the PHP file you're getting `$_POST['email']`, which means that it's getting the email sent by the client (if the backend will get another email that the client side can't know, then where/how it will be done?). Well, it seems that there is a *lot* of missing information, please edit the question ... (more) |

@#36363 "send data" means making a http request, using fetch with POST method (there's an example in the [docs](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch#supplying_request_options)).

Not sure if that's what you need, but if I understood correctly, it'd be something like this:

form.addEventListener('submit', function(e) {
e.preventDefault(); // don't submit the form

@#36363 Could you add a link to the website, so we can at least check the HTML and try to see what the problem is? Because your code *should* work.

Maybe - and that's a *wild guess* - the JavaScript code is running before the HTML is loaded, and it can't find the input field. Check if the `script` tag is before the form and change it to be after. Or add an event listener to run after the page is loaded:

@#36363 I've made a simple test:

@#53305 To add a little bit more pedantry, the filter predicate doesn't have to be exactly a boolean, because in Python [any object can be tested for truth value](https://docs.python.org/3/library/stdtypes.html#truth-value-testing). Which means I can do this:

@#54649 For quick performance tests you can use the [`timeit` module](https://docs.python.org/3/library/timeit.html). I've made [a simple example](https://ideone.com/xjEhaR), and creating the function inside the loop was about 50%~60% slower. (more) |

| Comment | Post #284806 |
You're creating the function inside the loop, so for every iteration a new function is created. But that's not needed at all, creating it just once outside the loop is enough.
Not sure how much it'll improve performance, but it certainly won't make it worse (more) |

Whether is cheap or not, it depends. If you think it is, then go for it :-)

If you're just looking for a shorter way to write the left-to-right mark character, there isn't.

If that's a good idea, it depends on what you need.

Complementing the comment above, when you set the value of something, you're replacing the old value by the new one, which is the same as changing the value.

`open` accepts only one URL. You'll probably have to add a callback after the first request is finished:
