A Guide to Dynamic href Links in HTML

Have you ever faced a situation where you needed a link that points to a dynamically generated URL? Perhaps you have an invisible HTML <a> tag created by a script, and your task is to redirect users based on that href value when they click on a different, visible link. Unfortunately, you can't use <script> tags or external JS files.

In this guide, we’ll explore how to solve this problem using a clever approach with JavaScript directly embedded in your HTML.

Understanding the Problem

Imagine this scenario:

There's a hidden <a> tag on your page that has a specific href you need to access.

A user interacts with a visible link, and you want to redirect them to that href.

The hidden tag might look something like this:

And your visible link might be:

Since you cannot use script tags or external JavaScript files, how do you make the redirection happen?

Solution: Using the onclick Event

Step 1: Embed JavaScript in the Anchor Tag

To achieve the required functionality without external scripts, we will use the onclick event handler directly on the visible <a> tag. This allows us to access the hidden <a> tag and grab its href value when the user clicks the visible link.

Step 2: Write the Code

Here’s how you can implement this solution:

Explanation of the Code:

Hidden Link: The hidden anchor tag where the dynamic URL is stored.

Visible Link: The visible link that users will click on.

onclick Event: This is a JavaScript function executed when the user clicks on the visible link. Inside the function:

We call .getAttribute('href') to get the href value of the hidden link.

Benefits of This Approach

No External Dependencies: This method does not rely on external JavaScript files or <script> tags, making it lightweight and simple to implement.

Easy Customization: You can easily modify the action associated with the onclick event to suit your specific requirements.

Conclusion

In this post, we explored how to dynamically redirect users to a URL stored in a hidden <a> tag using JavaScript within an HTML element. This solution is particularly useful in environments where adding external scripts is not feasible.

By embedding the JavaScript directly in the onclick event of the visible link, you achieve effective redirection while keeping your code clean and efficient.
