javascript change url with code examples

Javascript has revolutionized the way web development is done. With the help of it, developers can create interactive and dynamic websites that allow users to interact seamlessly with the website. One of the features of Javascript is that it allows developers to change URL without refreshing the page, which can enhance user experience. In this article, I will discuss the various ways in which Javascript can change the URL and provide examples of code snippets to show how it can be done.

The Importance of Changing URL without Refreshing the Page:

Before we delve deep into how Javascript can change URLs, let's understand the significance of this feature. The ability to change URLs dynamically without refreshing the page is essential for web applications that require frequent updates. It allows developers to create a seamless user experience where users can navigate the website without interruption. In addition, changing URLs dynamically enables developers to use back and forward buttons, bookmarks, and the address bar to control the user's browsing experience.

Ways of Changing URLs in Javascript:

There are several ways in which Javascript can change URLs. Here are the most common:

  1. Using the Location Object:

The Location object is a built-in object in Javascript that provides information about the current URL of a page. It allows developers to change the URL of a page using the assign() method. For example, the following code changes the URL to https://www.google.com/:

location.assign("https://www.google.com/");

Alternatively, the following code changes the URL to a relative path:

location.href = "/new-page";
  1. Using the Window Object:

The Window object is a global object in Javascript that represents the current browser window or tab. It provides several methods that allow developers to change the URL, such as the open() method. For example, the following code opens a new window and loads the URL https://www.google.com/:

window.open("https://www.google.com/");
  1. Using the HTML5 History API:

The HTML5 History API provides developers with methods to manipulate the browser history and change the URL without refreshing the page. It includes methods like pushState() and replaceState(). The pushState() method adds a new state to the browser history, whereas the replaceState() method replaces the current state with a new one. For example, the following code changes the URL to /new-page and adds a new state to the browser history:

history.pushState({page: "new-page"}, "New Page", "/new-page");
  1. Using the hash symbol:

The hash symbol (#) is commonly used in URLs to denote a location within a webpage. When the hash symbol is used in a URL, it does not cause the browser to reload the page. Developers can change the URL of a page by modifying the hash symbol using the location.hash property. For example, the following code changes the URL to https://www.example.com/#new-page:

location.hash = "#new-page";

Code Examples:

Here is a collection of code snippets that demonstrate how to change the URL using various methods available in Javascript:

  1. Using location.assign():
<button onclick="changeURL()">Change URL</button>

<script>
function changeURL() {
  var url = "https://www.google.com/";
  location.assign(url);
}
</script>
  1. Using window.open():
<button onclick="openWindow()">Open Window</button>

<script>
function openWindow() {
  var url = "https://www.google.com/";
  var windowName = "Google";
  var windowFeatures = "width=800,height=600";

  window.open(url, windowName, windowFeatures);
}
</script>
  1. Using HTML5 History API:
<button onclick="changeURL()">Change URL</button>

<script>
function changeURL() {
  var stateObj = { page: "new-page" };
  var title = "New Page";
  var url = "/new-page";

  history.pushState(stateObj, title, url);
}
</script>
  1. Using the hash symbol:
<button onclick="changeURL()">Change URL</button>

<script>
function changeURL() {
  var hash = "#new-page";
  location.hash = hash;
}
</script>

Conclusion:

In conclusion, changing URLs without refreshing the page provides a better user experience for web applications. It allows developers to create a seamless browsing experience and enhances the functionality of the website. Javascript provides various methods for changing URLs, such as using the Location and Window objects, the HTML5 History API, and the hash symbol. Developers can choose the method that best suits their needs based on the requirements of the web application.

I can provide more information about the previously discussed topics. Here is some additional information:

  1. Location Object:

The Location object is a built-in object in Javascript that contains information about the current URL that is loaded in the browser window. It includes properties like href, protocol, host, hostname, port, pathname, search, and hash. Developers can use the Location object to change the URL of a page using the assign() method or modify the URL components individually using the corresponding properties.

Here are some examples of using Location object property:

  • accessing the current URL:
console.log(location.href);
// output: https://www.example.com/page/home
  • changing the URL with assign() method:
location.assign("https://www.example.com/page/about");
  • modifying the URL parameters:
location.search = "?page=about";
  1. Window Object:

The Window object is a global object in Javascript that represents the current browser window or tab. It provides several methods that allow developers to interact with the browser window and its content, such as the open() method, close() method, alert() method, and confirm() method. Developers can also use the Window object to change the URL of a page by opening a new window and loading the URL in it using the open() method.

Here are some examples of using the Window object methods:

  • opening a new window:
window.open("https://www.example.com/page/about", "About Page", "width=400,height=400");
  • closing the current window:
window.close();
  • displaying an alert message:
window.alert("Hello world!");
  1. HTML5 History API:

The HTML5 History API provides developers with methods to manipulate the browser history and change the URL without refreshing the page. It includes methods like pushState() and replaceState(). The pushState() method adds a new state to the browser history, whereas the replaceState() method replaces the current state with a new one. Developers can also use the popstate event to detect when the user navigates through the history using the back and forward buttons.

Here are some examples of using the HTML5 History API:

  • adding a new state to the history:
history.pushState({page: "about"}, "About Page", "/page/about");
  • replacing the current state:
history.replaceState({page: "contact"}, "Contact Page", "/page/contact");
  • detecting when the user navigates through the history:
window.addEventListener("popstate", function(e) {
  console.log(e.state);
});
  1. Hash Symbol:

The hash symbol (#) is commonly used in URLs to denote a location within a webpage. When the hash symbol is used in a URL, it does not cause the browser to reload the page. Developers can change the URL of a page by modifying the hash symbol using the location.hash property. The hashchange event can be used to detect when the hash symbol changes.

Here are some examples of using the hash symbol:

  • changing the hash symbol:
location.hash = "#about";
  • detecting when the hash symbol changes:
window.addEventListener("hashchange", function(e) {
  console.log(location.hash);
});

In conclusion, Javascript provides developers with various methods to change the URL of a page without refreshing it. By using these methods, developers can create a more seamless and interactive browsing experience for their users.
