Методы переадресации JavaScript
В JavaScript window location или объект location используется, чтобы получить информацию о местоположении текущей веб-страницы (документа), а также для его изменения. Ниже приведен список способов, которые могут быть использованы для реализации переадресации JavaScript:
//Устанавливает новое местоположение текущего окна.
window.location = "http://www.example.com";
//Устанавливает новую гиперссылку (URL) для текущего окна.
window.location.href = "http://www.example.com";
// Присваивает новый URL текущему окну.
window.location.assign("http://www.example.com");
//Заменяет положение текущего окна на новое.
window.location.replace("http://www.example.com");
//Задает местоположение самого текущего окна.
self.location = "http://www.example.com";
// Задает положение самого верхнего окна относительно текущего.
top.location = "http://www.example.com";
Хотя приведенные выше строки JavaScript кода выполняют схожую работу, у них есть небольшие отличия. Например, если вы используете перенаправление top.location внутри элемента iframe, то это принудительно перенаправит на главное окно. Еще один момент, о котором стоит помнить: location.replace() заменяет текущий документ, удаляя его из истории и делая его недоступным с помощью кнопки «Назад» в браузере.
Для реализации кроссбраузерности мы рекомендуем использовать следующий код JavaScript windows location:
window.location.href = "http://www.example.com";

JavaScript Redirect: Redirect the Page After an Event or User Action
Sometimes, you may want to send the user to another page after a certain event or action takes place, such as a button click, an option selection, a layout change, a form submission, a file upload, an image drag, a countdown timer expiration or things like that. In such cases, you can either use a condition check or assign an event to an element for performing the redirect. You can use the following two examples to give you a basic idea:
<script>
// Check if the condition is true and then redirect.
if ( ... ) {
window.location.href = "https://www.example.com";
}
</script>
The above code will do the redirection if the condition is true.
<script>
// onclick event is assigned to the #button element.
document.getElementById("button").onclick = function() {
window.location.href = "https://www.example.com";
};
</script>
The above code will do the redirection when the user clicks the #button element.
This is how JavaScript redirect basically works. We hope that the above examples will help you while handling your web page redirects.

Переадресация JavaScript: перенаправление со страницы после события или действия пользователя
Иногда нужно отправить пользователя на другую страницу после определенного события или совершенного действия. В таких случаях можно использовать проверку условия или закрепить за элементом событие для выполнения переадресации. Рассмотрим два следующих примера:
<script>
// Проверяем, верно ли условие, и затем перенаправляем.
if ( ... ) {
window.location.href = "http://www.example.com";
}
</script>
Приведенный выше код JavaScript document location href выполнит перенаправление, если условие верно:
<script>
// событие onclick присвоено элементу #button.
document.getElementById("button").onclick = function() {
window.location.href = "http://www.example.com";
};
</script>
Приведенный выше код выполнит перенаправление, когда пользователь нажмет на элемент #button.
Так работает переадресация в JavaScript. Надеемся, эти примеры помогут вам в организации переадресации веб-страниц.

JavaScript Redirect Methods
You can redirect a web page via JavaScript using a number of methods. We will quickly list them and conclude with the recommended one.
In JavaScript, window.location or simply location object is used to get information about the location of the current web page (document) and also to modify it. The following is a list of possible ways that can be used as a JavaScript redirect:
// Sets the new location of the current window.
window.location = "https://www.example.com";
// Sets the new href (URL) for the current window.
window.location.href = "https://www.example.com";
// Assigns a new URL to the current window.
window.location.assign("https://www.example.com");
// Replaces the location of the current window with the new one.
window.location.replace("https://www.example.com");
// Sets the location of the current window itself.
self.location = "https://www.example.com";
// Sets the location of the topmost window of the current window.
top.location = "https://www.example.com";
Though the above lines of JS code accomplish a similar job in terms of redirection, they have slight differences in their usage. For example, if you use top.location redirect within an iframe, it will force the main window to be redirected. Another point to keep in mind is that location.replace() replaces the current document by moving it from the history, hence making it unavailable via the Back button of the browser.
It is better to know your alternatives but if you want a cross-browser compliant JavaScript redirect script, our recommendation will be to use the following in your projects:
window.location.href = "https://www.example.com";
Simply insert your target URL that you want to redirect to in the above code. You can also check this page to read more about how window.location works. Now, let’s continue with our examples.
