@#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)). And you can use [`FormData`](https://developer.mozilla.org/en-US/docs/Web/API/FormDat... (more) |

@#36363 Then I suggest you to edit the question and add this information there.
But anyway, if you want to execute behavior.php, you'll have to send data to it (which is basically what I described above) (more) |

After the last edit it's still unclear what you mean by "*apply backend behavior*".
Do you have a `form action="URL A"` and want to send all its data to URL B using JavaScript? (more) |

Not sure if that's what you need, but if I understood correctly, it'd be something like this:
```javascript
let form = // get the form somehow (for example, with querySelector)
form.addEventListener('submit', function(e) {
e.preventDefault(); // don't submit the form
fetch('backend.url... (more) |

A: What does a variable followed by parentheses ("ptr()") mean? `void (ptr)()` defines a function pointer. It says that `ptr` is a pointer to a function. But that function must have a `void` return type, and take an arbitrary number of parameters (that's what the empty parentheses defines). Then, `ptr = PrintHello` assigns the `PrintHello` function to th... (more) |

@#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.
Just double checking the basic stuff: what does `document.querySelector("#example")` return? When you run your code, does any error message appear i... (more) |

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:
```javascript
document.addEventLis... (more) |

@#36363 I've made a simple test:
```javascript
var old = document;
document.write('abc');
console.log(old === document); // true
```
Which means that the document didn't change (only its child nodes). Another test to check if child nodes changed:
```javascript
// keep reference to ori... (more) |

@#36363 My understanding is that the document itself is not removed, only its child nodes. But I'll make more tests as soon as I can (more) |

A: document.open() and the DOM tree of the loaded (closed) browser window on which it works At the documetation you linked, if you click on "which will clear the document", it'll go to the documentation for `document.open`, and that page says in the beginning: > All existing nodes are removed from the document. And once removed, you can't retrieve them. Making a test in this pa... (more) |

Code block in comments is highlighted only when viewed in the thread's link Code blocks inside comments are hightlighted only if I'm on the comment's thread page. If I view it on the post itself (after expanding the respective thread), it's not highlighted.

@#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:
```python
values = ['abc', '', []... (more) |

A: Change font-family with JavaScript To do that, you could change the selector from `body` to ``, as the other answer said. By selecting only `body`, it won't change child elements that has defined a more specific rule, and that's why you need to set the style for all of them. But there are some corner cases that I think it's wor... (more) |

@#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) |

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) |

A: Separate digits of a number in groups with different sizes Before we start, I'd like to be a little bit pedantic regarding `00002451018` being a number. When we talk about numeric types/values, the zeroes at the beginning are irrelevant: `2`, `02` and `000002` all refer to the number two. The numeric value is `2`, and only the representation - the way... (more) |
