Stop implementation setInterval

irl

$(setInterval (function() { 
    if ( $("#online_counter").html() == 1) {
        $("wrapper").hide();
    }
    if ( $("#online_counter").html() == 2) {
        window.location.replace(document.location.href);
        $("wrapper").show();
    }
}, 3000 ));

Distinguished, can jQuery stop performance setIntervalwhen condition 2 is fulfilled?

Mystic

Second condition bodyif ( $("#online_counter").html() == 2) { Reloads the page, which already suggests a bad code and approach. Set a variable ID interval and clean it up:

$(function() {
  let id = setInterval(function() { // setInterval возвращает уникальный ID вида: 3681
    if ($("#online_counter").html() == 1) {
      $("wrapper").hide();
    }
    if ($("#online_counter").html() == 2) {
      clearInterval(id); // Функция уничтожения интервала по ID
      $("wrapper").show();
    }
  }, 3000)
});

Has a if checking if the message is equal ERROR, but there is no action if it is different from that. You can put a window.location.href='pagina que deseja'. You won't be able to redirect with that code. if ( LoginController.getInstance().authenticateUser( request, response ) ) { response.sendRedirect( "home.jsp" ); } Instead do response.getWriter().println( "home.jsp" );And in javascript: if ( $.trim( msg ) === "ERROR" ) { loginErrorAlert(); $( '#userLogin' ).val( "" ); $( '#userPassword' ).val( "" ); $( '#userLogin' ).focus(); }elseif($.trim( msg ) === "home.jsp") { window.location.href= $.trim( msg ); } A better solution would be to use the http response codes, and if that was wrong it would return a 403 for example. And with that you would add a function error{ //código }, shortly after success in javascript

You are told that you probably have two options to follow this class and perform all of its functions (but it is unlikely that there is no virtual destructator and that there is a private section that should not have intrephes).Therefore, it is likely that the exercise of functions should be simply written.template<class T> class Stack { public: Stack(); ~Stack(); Stack( const Stack& ); Stack& operator=( const Stack& ); size_t Count() const; void Push( const T& item); T Рор(); // throws an exception if stack is empty private: std::vector<T> m_data; }; and beyondsize_t Stack::Count() const { return m_data.size(); } void Stack::Push( const T& item) { m_data.push_back(item); } And so on. ♪ ♪

It's not right to make a request.The request is not made on the client. (There's a danger of injecting the request.) (what if you simply replace the meaning fullsqlcondition ♪ drop Database)For the server, shape parameters (names of selected inputs: textboxes, cheekboxes, radio ....). The following server calls and returns the client response.UPDExample https://stackoverflow.com/questions/21164884/ajax-post-and-get-checkbox-value .ajax( { type: 'POST', url: '/ajax/checkbox.php', data: { foton : $('input:checkbox:checked').val()}, success: function(data) { $('#message').html(data); } } );

I believe your example problem is in ng-options, try to replace with:ng-options="item as item.value for item in itens" Next I have an example that works in a more simplified scenario that you can base yourself:<div ng-app> <script> function MyController($scope) { $scope.colors = [ { name: 'black', shade: 'dark' }, { name: 'white', shade: 'light' }, { name: 'red', shade: 'dark' }, { name: 'blue', shade: 'dark' }, { name: 'yellow', shade: 'light' } ]; } </script> <div ng-controller="MyController"> <select ng-model="selectedItem" ng-options="color as color.name for color in colors" class="form-control"> </select> </div> </div>

In Unity there is no possibility of avoiding the implementation of the consequent calls to https://docs.unity3d.com/ScriptReference/MonoBehaviour.Update.html even if the counter is finished, so you must maintain a variable to know whether the counter is active or a value of the counter to determine that the counter is inactive.One solution could be with a variable that stores the status of "active accountant" and another could be establishing a reserved value for when the counter is inactive (e.g. value -1).Variable statususing UnityEngine; using System.Collections; public class CuentaAtras : MonoBehaviour { public int tiempo; public bool habilitado; // Use this for initialization void Start() { /* Marcamos el contador como habilitado */ habilitado = true; } // Update is called once per frame void Update() { /* Comprobamos si el contador está habilitado */ if (habilitado == true) { if (tiempo > 0) { tiempo = tiempo - 1; Debug.Log(tiempo); } else { Debug.Log("Se acabo el tiempo"); /* Marcamos el contador como deshabilitado */ habilitado = false; } } } } Special value for final statususing UnityEngine; using System.Collections; public class CuentaAtras : MonoBehaviour { public int tiempo; // Use this for initialization void Start() { } // Update is called once per frame void Update() { /* Comprobamos si el contador sigue activo */ if (tiempo != -1) { if (tiempo > 0) { tiempo = tiempo - 1; Debug.Log(tiempo); } else { Debug.Log("Se acabo el tiempo"); /* Marcamos el tiempo como finalizado */ tiempo = -1; } } } }

Your algorithm to break down on prime factors can be improved.The algorithm used is the one we've all used in high school math classes:If N is pair, it is divided between 2 and the result is pointed out.If N is unstoppable, we try to divide between the next odd prime number (3, 5, 7,...) until we get an exact division and the result is scoredStep 1 or 2 is again applied to the result of the previous division, and it begins again.We must establish a mechanism to store the amount of times our prime factor appears in decomposition.We already have the bricks necessary to build our function.One way we can write the function would be the following:function descomponerEnPrimos(N) { var arr = []; //aqui almacenamos los factores temporalmente var resultado = N;// el primer valor que usaremos es N while(resultado > 1) { // 'resultado' irá variando hasta hacerse 1 for (var i = 2; i<= N; i++) { // vamos realizando pruebas if(resultado % i === 0) { resultado = resultado / i; //actualizamos el valor de resultado arr.push(i); break; // salimos del bucle for } } } var factores = []; // aqui almacenaremos los factores de forma mas legible var factor = arr[0]; // almacenamos el primer valor var cont = 1; // instanciamos la cantidad de veces que aparece el primer elemento if (arr.length > 1) { // si hay más de 1 elemento en el array for(var i = 1; i < arr.length; i++){ if (factor !== arr[i]) { // si el factor cambia, ya no se repite más, podemos almacenarlo factores.push({factor: factor, seRepite: cont}); factor = arr[i]; // establecemos el nuevo factor cont = 0; // inciamos el contador en cero, en la siguiente linea aumentará 1 } cont++; // si el factor se repite, aumentamos el contador, si estaba en cero se aumenta a 1 } factores.push({factor: factor, seRepite: cont}); // almacenamos el último factor encontrado } else { // en caso que N sea primo, solo tiene un factor factores.push({factor: factor, seRepite: cont}); } return factores; } With this function we already have a way to calculate decomposition in prime factors of any positive integer.One way to implement this function to show the result would be:function descomponerEnPrimos(N) { var arr = []; //aqui almacenamos los factores temporalmente var resultado = N;// el primer valor que usaremos es N while(resultado > 1) { // 'resultado' irá variando hasta hacerse 1 for (var i = 2; i<= N; i++) { // vamos realizando pruebas if(resultado % i === 0) { resultado = resultado / i; //actualizamos el valor de resultado arr.push(i); break; // salimos del bucle for } } } var factores = []; // aqui almacenaremos los factores de forma mas legible var factor = arr[0]; // almacenamos el primer valor var cont = 1; // instanciamos la cantidad de veces que aparece if (arr.length > 1) { // si hay más de 1 elemento en el array for(var i = 1; i < arr.length; i++){ if (factor !== arr[i]) { // si el factor cambia, ya no se repite más, podemos almacenarlo factores.push({factor: factor, seRepite: cont}); factor = arr[i]; // establecemos el nuevo factor cont = 0; // inciamos el contador a cero, ya que se aumentará a 1 en la siguiente linea } cont++; // si el factor se repite, aumentamos el contador } factores.push({factor: factor, seRepite: cont}); // almacenamos el último factor encontrado } else { // en caso que N sea primo, solo tiene un factor factores.push({factor: factor, seRepite: cont}); } return factores; } function calcular() { //instanciamos el elemento de salida var salida = document.getElementById('salida'); //capturamos el entero var entero = Number.parseInt(document.getElementById('entero').value); // si el valor no es un numero valido salimos if(Number.isNaN(entero)){return;} // llamamos a la funciona que calcula los factores primos var factoresPrimos = descomponerEnPrimos(entero); // construimos el string del resultado var resultado = entero.toString() + " = "; for(var i = 0; i < factoresPrimos.length; i++) { //usaremos el 'tag' <sup> de HTML resultado += (factoresPrimos[i].factor).toString() + "<sup>" + (factoresPrimos[i].seRepite).toString() + "</sup>" + (i < factoresPrimos.length - 1 ?
