How to Pass Parameters to a Destination URL Using JavaScript

When developing web applications, you may need to pass information between pages, especially when a user clicks on an item like a movie. For instance, you might want to redirect users to a movie details page while simultaneously sending along the movie's unique identifier. This is a common requirement in applications and can be easily achieved with JavaScript.

In this guide, we'll explore how to pass parameters to a destination URL using JavaScript effectively. We'll focus on a real-world scenario: directing users from a homepage to a movie details page, along with the movie ID as a URL parameter. Let's get started!

The Problem: Passing a Movie ID

Imagine you have a homepage with a list of movies. Each movie features an anchor tag that, when clicked, should redirect the user to a detailed view of that movie. You want the URL of the destination page to look something like this:

Here, 1234 represents the unique ID for the movie.

The Solution: Adding Parameters to the Anchor Tag

To implement this functionality, you simply need to modify the href property of the anchor tag to include the desired parameter directly. Here’s a step-by-step breakdown of how to do this:

Step 1: Modify the HTML Structure

Start with your existing HTML structure for the movie item as shown below:

Step 2: Update the href Attribute

You need to append the movie ID as a query parameter in the URL. Update the href attribute in the anchor tag as follows:

Step 3: Dynamic Movie IDs

In a real-world scenario, the movie ID should be dynamic. If you're looping through movie data, you might do something like this in your JavaScript code:

And integrate it into the anchor tag dynamically:

Step 4: Retrieving the Movie ID on the Destination Page

Once you have redirected the user to the movie details page, you might want to retrieve the movie ID. You can do this with the following JavaScript code snippet:

Conclusion

Passing parameters to a destination URL using JavaScript is a straightforward process. By modifying the href attribute of anchor tags, you can effectively send necessary data to other pages. This technique is especially useful in scenarios like eCommerce, blogs, or movie websites, where user navigation and data persistence are crucial.

Now, whenever a user clicks on a movie, they’ll be taken to the correct page with the movie ID included. This makes your application more dynamic and improves the user experience. Happy coding!
