how not to make unnecessary values in the field So nothing happens. You know, you know, there's no entry in the field.
js
```
var input = document.getElementById('place'),
       reg = "/^[\d]+$/g";
    input.value = input.value.replace(reg, '');
```

Your code should look like:
```
var input = document.getElementById('place'),
input.value = input.value.replace(/[^\d]/g, '');
```
So mean, we're removing all the numbers.

To date, a solution has been found: mainweb.Document.GetElementById("double_your_btc_stake").SetAttribute("value", "0.000002"); HtmlDocument doc = mainweb.Document; HtmlElement head = doc.GetElementsByTagName("head")[0]; HtmlElement s = doc.CreateElement("script"); s.SetAttribute("text", "function keyEvent() { $(document.getElementById('double_your_btc_stake')).keydown(); }"); head.AppendChild(s); mainweb.Document.InvokeScript("keyEvent");

To answer your question: [:ascii:] works. You may have some characters in your text that you do not recognize as non-ASCII, yet they're there. They can be something like a non-breakable space, for instance, or any other Unicode space character. It is not strange to have non-breakable spaces ( ) in texts that you copy-and-paste from a web page, yet you don't notice they're there. Here is an example to show: WITH t(t) AS ( VALUES ( 'Сталинская правозащитница: мать Меленкова бабушка Настя' ), ( 'Дневник НКВДиста Шабалина: Знает ли Москва положение на фронте?' ), ( 'Бег по городу и поездка на осле: как в средневековье наказывали прелюбодеев' ), ( 'Как комиссар Крекшин в 1740-е чуть не отменил историю России' ), ( 'Have you heard of Saint Death? Don’t pray to her.' ), ( 'Архаїчна українська мова: перевага чи недолік?' ), ( 'Гренада не их' ), ( 'China’s marriage rate is plummeting because women are choosing autonomy over ' ) ) SELECT t, regexp_replace(t, '([^[:ascii:]])', '[\1]', 'g') AS t_marked FROM t WHERE t ~ '[^[:ascii:]]' ; That's what you get: t | t_marked -------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Сталинская правозащитница: мать Меленкова бабушка Настя | [С][т][а][л][и][н][с][к][а][я] [п][р][а][в][о][з][а][щ][и][т][н][и][ц][а]: [м][а][т][ь] [М][е][л][е][н][к][о][в][а] [б][а][б][у][ш][к][а] [Н][а][с][т][я] Дневник НКВДиста Шабалина: Знает ли Москва положение на фронте? | [Д][н][е][в][н][и][к] [Н][К][В][Д][и][с][т][а] [Ш][а][б][а][л][и][н][а]: [З][н][а][е][т] [л][и] [М][о][с][к][в][а] [п][о][л][о][ж][е][н][и][е] [н][а] [ф][р][о][н][т][е]?

a.m. - Readingstd::fstream f("файл"); int number; while (f >> number) { // добавьте в массив vector.push_back(number); } But here's the condition "without the C-style, please and without the vectors." Because we're gonna have to set up a dynamic body. And it's either a malloc (net water) or a new + index (and it's actually a stale, though not a sec).So, use the vector, it's good with++ style. Or show me how you see a dynamic set of s++ style and I'll finish the answer.

Galera, after exploring a little more and analyzing the suggestions I arrived in the following solution.<script type="text/javascript"> $(document).ready(function () { var $body = $('body'); var $pageSidebar = $('.page-sidebar'); var $pageContainer = $('.page-container'); $body.scroll(function (event) { if ($pageContainer.offset().top > 0) { $pageSidebar.css("top", $pageContainer.offset().top + "px"); } else { $pageSidebar.css("top", "0px"); } }); }); </script> I gave up the use of scrollTop() because it was presenting a very unstable behavior which is not good for application.

So I understand you want to do, you should set the field of the board as identity. This makes you not have to insert it, the database engine will only calculate it.This is part of the table definition (You should add it with an alter table, or drop the table and create it again, always exporting the data) and takes two parameters: seed e increase, being seed the initial value and increase being the value for which it will be added, and is used as follows:IDENTITY [ (seed , increment) ] I'close the documentation to you: https://docs.microsoft.com/en-us/sql/t-sql/statements/create-table-transact-sql-identity-property?view=sql-server-ver15 All you have to take into account is that under certain circumstances, such as failed inserts for example, identity will increase even if no data has been inserted, so you will have a numerical leap.If the latter is a problem, the simplest thing before inserting is to bring the last data and insert the corresponding one, blocking the table.And I add a simple example, where the field begins in 1 and increases from 1:create table Sedes ( id bigint not null primary key identity (1,1), nombre varchar(100) not null, idLocalidad bigint not null foreign key (idLocalidad) references Localidades(id), direccion varchar(100) not null, telefono int null check (telefono > 0), mail varchar(100) null, unique (idLocalidad, direccion) ); Reviewing your update, I understand that the best way to move forward, as you require that the customer ID necessarily increase consecutively without jumps (Identity would not serve you), I think the best way to move forward would be by means of a instead of insert trigger on your table, to get the right ID, where you would replace the id you are inserting by which you calculate the lastcreate trigger TR_GetLastID on TablaDondeLoNecesites after insert as begin declare @codCliente bigint select @codCliente = max(inserted.codCliente) from inserted insert into TablaDondeLoNecesites (codCliente + 1, demásDatos...) end GO

The problem is that while the field has no value, the attribute value it will be undefined. If you try to add any value with undefined the result will be NaN.The solution is you consider the zero value when the attribute is not set doing something like var a = id('a').value || 0.function id(el) { return document.getElementById(el); } function calcular(el) { var a = id('a').value || 0; var b = id('b').value || 0; var c = id('c').value || 0; id('d').value = parseInt(a) + parseInt(b) + parseInt(c); }<input type="number" id="a" value="0" name="a" onkeyup="calcular()" onkeydown="calcular()" /> + <input type="number" id="b" value="0" name="b" onkeyup="calcular()" onkeydown="calcular()" /> + <input type="number" id="c" value="0" name="c" onkeyup="calcular()" onkeydown="calcular()" /> = <output id="d">0</output>Other considerations:Define the attribute value as 0 initially, because this helps in user orientation;I'll change the guy from the fields to number to enjoy native basic validations;I changed the result field to <output> to improve the semantics of the document;I added the mathematical operators between the fields to improve reading;

To achieve this goal, you can use this solution:First you must:Create table userSubmitControl with the following fields: idUser and submitStatus;Create a script (s2) to check whether the user has already posted or not. This is technically checking whether the field submitStatus equals fake (false) or truth (true).Create a script to change the field submitStatus for false, if this is true, and this script should run every day at midnight according to the datetime of the bank.Second:When the user submits you must first check through the s2 script if you can or not, if yes, proceed with the submit and then update the field for truth; and, if not, stop the submit and for all.NB: You can use the table information userSubmitControl to control the button.

We use a window method with two indices. Create a structure to store the vocabulary with the cell counters - Python has collections.Counter♪We'll set both indices zero. Moving the right index, for every new element entering the window, updating his counter to the window. CounterLet's check the size. Counter (Number of different elements with a non-zero counter, we call it Distinct) Every step of this phase exists WinLen = right-left+1 good submasses ending in right♪ WinLen to outcome. As soon as Distinct Over K - Wait.Move the left index. For every element that leaves the window, we' cut the counter. As soon as Distinct (through removal of elements with zero counter) K - Wait.Repeat the previous two steps before the end of the list/bassy. Linear algorithm, as both indices move only forward (+ counter costs)

It's a little cozy but it works. And... there's got to be a better way to shut down the event when it's worked... but I don't know that yet. So at least through. return; You can reduce the volume of extra calculations.(function(){ let counter = document.querySelectorAll('.counter'); let limit = 0; // Переменная, чтобы останавливать функцию, когда всё запустится. window.addEventListener('scroll', function(){ if( limit == counter.length ){ return; } for(let i = 0; i < counter.length; i++){ let pos = counter[i].getBoundingClientRect().top; //Позиция блока, считая сверху окна let win = window.innerHeight - 40; // На 40 пикселей меньше, чем высота окна if( pos < win && counter[i].dataset.stop === "0" ){ counter[i].dataset.stop = 1; // Останавливаем перезапуск счета в этом блоке let x = 0; limit++; // Счетчик будет запущен, увеличиваем переменную на 1 let int = setInterval(function(){ // Раз в 60 миллисекунд будет прибавляться 50-я часть нужного числа x = x + Math.ceil( counter[i].dataset.to / 50 ); counter[i].innerText = x; if( x > counter[i].dataset.to ){ //Как только досчитали - стираем интервал. counter[i].innerText = counter[i].dataset.to; clearInterval(int); } }, 60); } } }); })();.counter { width: 200px; margin: 400px 0 200px 0; border: 2px solid orange; font-size: 30px; color: #045acf; text-align: center; }<div class="counter" data-to="26" data-stop="0">0</div> <div class="counter" data-to="1000" data-stop="0">0</div> <div class="counter" data-to="2500000" data-stop="0">0</div>

We'll use 3 array. One will have all the numbers, another will have odd numbers and the last will have pair numbers. By modulus and comparison of residue with 0 We'll know if it's a pair or not. %2==0.Once we have separated our values, we will use the created function average() to get the average.<?php $numbers = [1,2,3,4,5,6,7,8,9,10]; $pares = array(); $impares = array(); foreach($numbers as $number){ if(is_par($number)){ array_push($pares, $number); }else{ array_push($impares, $number); } } if(empty($numbers)){ die("No se pueden obtener datos desde un array vacio."); } echo "Promedio pares: " . average($pares) . " Numeros: " . implode(",", $pares); echo " Total impares: " . count($impares) . " Numeros: " . implode(",", $impares); function is_par($number){ return $number % 2 == 0; } function average($values){ $values = array_filter($values, function($x) { return $x !== ''; }); $average = array_sum($values) / count($values); return $average; }

The task is incorrect. A copy of the Date may not, in general, represent the difference in time between the two dates.The presentation of the date depends on the elbow, therefore it is necessary either to monitor the same logic or to use its own format (see java.text.DateFormat).
