Getting the Page URL with JavaScript

Getting the Page URL with JavaScript

In web development, it is often necessary to obtain the page URL for various purposes such as tracking, form validation, or dynamically generating content. JavaScript provides multiple methods to accomplish this task. In this article, we will explore four different methods to get the page URL using JavaScript.

Method 1: Using the window.location object

The window.location object provides access to the current page URL and its various components. One of the simplest ways to obtain the page URL is by using the window.location.href property. This property returns the full URL of the current page.

const pageUrl = window.location.href;
console.log(pageUrl);

Additionally, the window.location object also provides other properties to extract specific parts of the URL. For example, window.location.protocol returns the protocol of the URL (e.g., "http" or "https"), window.location.hostname returns the domain name, window.location.pathname returns the path of the URL, and window.location.search returns the query string.

Method 2: Using the document.URL property

Another way to obtain the page URL is by using the document.URL property. This property returns the full URL of the current page just like window.location.href.

const pageUrl = document.URL;
console.log(pageUrl);

Method 3: Using the location object

The location object is similar to window.location and provides access to the current page URL. To get the page URL, we can use the location.href property.

const pageUrl = location.href;
console.log(pageUrl);

Similarly, the location object also has other properties like location.protocol, location.hostname, location.pathname, and location.search to extract specific parts of the URL.

Method 4: Using the location.href property as a function parameter

In some cases, we may need to pass the page URL as a parameter to a function. We can achieve this by using the location.href property directly as an argument.

function processPageUrl(url) {
  // Perform some actions with the page URL
  console.log(url);
}

processPageUrl(location.href);

By utilizing these different methods, we can easily obtain the page URL in JavaScript for various purposes in web development.

Remember to experiment with these code snippets and incorporate them into your own projects. Understanding how to obtain the page URL is an essential skill that can enhance the functionality and interactivity of your web applications.

Introduction

In web development, it is often necessary to obtain the URL of the current page. This information can be useful for various purposes, such as tracking user behavior, dynamically updating content, or generating links.

JavaScript provides several methods to retrieve the page URL, making it easy to access this information within your code. In this article, we will explore different techniques to obtain the page URL using JavaScript.

Throughout this post, we will provide code snippets demonstrating each method. By following along and experimenting with these examples, you can gain a deeper understanding of how to retrieve the page URL in JavaScript.

Method 1: Using the window.location object

The window.location object provides information about the current URL of the page. It has several properties that can be used to obtain different parts of the URL.

To obtain the current page URL, you can use the window.location.href property. This property returns the complete URL of the page as a string. Here is an example code snippet:

const currentUrl = window.location.href;
console.log(currentUrl);

This will output the current page URL in the console.

In addition to window.location.href, the window.location object also has other properties that can be used to extract specific parts of the URL. For example:

• window.location.protocol returns the protocol of the URL (e.g., "http:", "https:")
• window.location.host returns the host name and port number of the URL
• window.location.pathname returns the path of the URL
• window.location.search returns the query string of the URL
• window.location.hash returns the anchor part of the URL (e.g., "#section1")

Here is an example code snippet that demonstrates how to use these properties:

const protocol = window.location.protocol;
const host = window.location.host;
const path = window.location.pathname;
const queryString = window.location.search;
const anchor = window.location.hash;

console.log(protocol);
console.log(host);
console.log(path);
console.log(queryString);
console.log(anchor);

By using these properties, you can extract specific parts of the URL as needed.

Using the window.location object is a common and straightforward way to obtain the page URL in JavaScript. It provides convenient access to various parts of the URL, allowing you to work with them in your web development projects.

Method 2: Using the document.URL property

The document.URL property is a built-in property of the document object in JavaScript that returns the current URL of the page. It is a string that includes the protocol, domain, and path of the URL.

To obtain the current page URL using document.URL, you can simply access the property:

const currentURL = document.URL;
console.log(currentURL);

This will log the current URL of the page to the console.

One advantage of using document.URL is that it provides the complete URL, including any query parameters or fragments. It is a reliable method for getting the page URL in JavaScript.

Keep in mind that document.URL is a read-only property, so you cannot modify the URL using this property. It can only be used to retrieve the current URL of the page.

Using document.URL is a straightforward and efficient way to obtain the page URL in JavaScript.

Method 3: Using the location object

The location object in JavaScript provides information about the current URL of the web page. It contains various properties that can be used to obtain different parts of the URL.

One of the most commonly used properties of the location object is href. It returns the complete URL of the current page. To get the page URL using location.href, you can use the following code:

const pageURL = location.href;
console.log(pageURL);

This will log the complete URL of the page to the browser's console.

In addition to href, the location object also provides other properties that can be used to extract specific parts of the URL. Some of these properties include:

• protocol: returns the protocol used in the URL (e.g., "http:", "https:", etc.)
• hostname: returns the domain name of the URL (e.g., "example.com")
• pathname: returns the path of the URL (e.g., "/blog")
• search: returns the query string of the URL (e.g., "?id=123")

To extract specific parts of the URL using these properties of the location object, you can use the following code:

const protocol = location.protocol;
const hostname = location.hostname;
const pathname = location.pathname;
const search = location.search;

console.log(protocol);
console.log(hostname);
console.log(pathname);
console.log(search);

This will log each part of the URL to the browser's console separately.

The location object provides a convenient way to obtain the page URL and its individual components in JavaScript. By utilizing its properties, you can easily access and manipulate the URL of the current web page.

Method 4: Using the location.href property as a function parameter

In some cases, you may need to pass the page URL as a parameter to a function. One way to do this is by using the location.href property.

The location.href property returns the complete URL of the current page as a string. By accessing this property and passing it as a parameter to a function, you can easily work with the page URL within the function.

Here's an example of how to pass the page URL as a parameter using location.href:

function processURL(url) {
  // Perform actions with the URL
  console.log("Processing URL:", url);
}

processURL(location.href);

In this code snippet, the processURL() function is declared, which takes a parameter called url. When calling the function, we pass location.href as the argument, which is the complete URL of the current page.

Within the processURL() function, you can perform any desired actions with the URL. In this example, we simply log the URL to the console using console.log().

By utilizing the location.href property as a function parameter, you can easily access and manipulate the page URL within your JavaScript functions. This can be particularly useful when you need to pass the URL to an AJAX request or when working with dynamic content on your webpage.
