How to redirect a web page using JavaScriptīefore looking at the jQuery code, let's first learn how to redirect a web page by using plain JavaScript. JQuery and JavaScript are mostly used for client-side redirection and there are a number of ways to redirect a web page using JavaScript In this tutorial, we'll examine some of the most popular and common ways to redirect a web page using JavaScript and jQuery.
