What is the current JS solution in Webflow to catch successful form submissions and redirect to a custom link with query parameters?

The current JavaScript solution in Webflow to catch successful form submissions and redirect to a custom link with query parameters is by utilizing the built-in Webflow form submission event and custom code.

To achieve this, follow these steps:

Step 1: Create a form in Webflow
First, you need to create a form using the form element in Webflow. Set up the required form fields and any other related settings.

Step 2: Add a custom code embed
Next, you'll need to add a custom code embed to your Webflow project. Place this embed code within the project settings or on the specific page where the form is located.

Step 3: Include JavaScript code
Inside the custom code embed, you can add JavaScript code that listens for the form submission event and performs the desired actions.

Here's an example of the JavaScript code you can use to catch successful form submissions and redirect to a custom link with query parameters:

```javascript

```

Make sure to replace `'your-form-id'` with the actual ID of your form. Also, modify the `redirectUrl` variable to the desired URL with your own query parameters.

With this code in place, when a user successfully submits the specified form, the JavaScript code will catch the event, construct the custom redirect URL, and perform the redirect with the query parameters.

Remember to test your form thoroughly to ensure that everything works as expected.
