JS Window Location Relative Path
As a web developer, it's important to understand how to work with paths in JavaScript. Sometimes, you may want to get the relative path of the current page, or navigate to a new page using a relative path. This is where the window.location
object comes in handy.
Getting the Relative Path
To get the relative path of the current page, you can use the window.location.pathname
property. This property returns the path of the current page relative to the domain name. For example:
const relativePath = window.location.pathname;
console.log(relativePath); // Output: "/blog/my-post.html"
In the above example, the relativePath
variable will contain the value "/blog/my-post.html"
if the current page is example.com/blog/my-post.html
.
Navigating to a Relative Path
You can also use the window.location
object to navigate to a new page using a relative path. To do this, you can set the href
property of the object to the relative path of the new page. For example:
window.location.href = "/blog/my-post.html";
In the above example, the browser will navigate to the page located at /blog/my-post.html
.
Using Relative Paths with Other Objects
It's worth noting that you can also use relative paths with other objects in JavaScript, such as the XMLHttpRequest
object for making AJAX requests. In this case, you would simply construct the relative path as a string and pass it to the object. For example:
const xhr = new XMLHttpRequest();
xhr.open("GET", "/api/posts");
xhr.send();
In the above example, the AJAX request is being made to the /api/posts
endpoint relative to the domain name.
Overall, understanding how to work with relative paths is an important skill for any web developer. By leveraging the window.location
object and other JavaScript objects, you can easily work with relative paths in your web applications.
