Redirecting to a Page in Oracle APEX Using JavaScript

Creating dynamic and interactive web applications often involves the need to redirect users to different pages based on their actions. In Oracle APEX, this can be achieved using JavaScript to pop up a new page while passing parameters seamlessly. In this guide, we will explore how to effectively handle such redirections using JavaScript code within the Oracle APEX environment.

The Problem

You might find yourself trying to open a new page in Oracle APEX and need to pass some ID values (like MERCHANT_ID) into the parameters of that new page. Below is an example of an initial attempt to create a JavaScript function that manages this redirect:

While this is a typical way to handle redirections, it might not work as expected, leaving users confused about how to properly include ID values in the URL. Let’s break down how to solve this issue.

The Solution: Using a Custom JavaScript Function

To redirect appropriately while ensuring that the necessary parameters are passed along, you can define a custom JavaScript function. Here is a step-by-step approach:

Step 1: Define the JavaScript Function

Firstly, we will create a JavaScript function that constructs the URL for the redirection and opens it in a new window. This can be done in the Page's HTML Header section:

In this code:

We define a function called openPopup().

Set the url variable that holds the redirection link with the required parameters.

Use window.open() to create a new window that displays this URL with specified dimensions and settings.

Step 2: Create a Clickable Link

To allow users to invoke this function, you will need to create a link that calls openPopup(). You can add a Text Field item on your page and input the following code in its Post Text setting:

This snippet creates a clickable link labeled “Popup”. When users click it, the openPopup() function is triggered, and the configured page opens up in a new window.

Step 3: Testing Your Implementation

Once you've implemented the above code on your Oracle APEX application, it's crucial to test its functionality:

Click the “Popup” link and ensure that a new window opens.

Check that the correct parameters, like MERCHANT_ID, are passed and displayed on the newly opened page.

Conclusion

By following these steps, you’ll be equipped to create an interactive experience for your users in Oracle APEX. Redirecting to a new page using JavaScript while passing along essential parameters not only enhances user interaction but also streamlines your application’s functionality.
