In this guide, we’ll walk through a solution for passing data from a modal component into a submit handler, allowing you to submit form data seamlessly.

The Problem

In your current implementation, when you click to open a modal and fill out a form, you encounter an issue where the submit handler cannot access the form data. This could occur due to the lack of proper data binding between the modal and the parent component.

Requirements:

Establish data binding for form inputs within the modal.

Emit the entered data back to the parent component upon submission.

The Solution

To achieve the desired functionality, you’ll need to follow these key steps:

1. Update Emit Events in the Modal

First, you need to allow your modal component to emit events for both closing the modal and submitting the form. In your modal component, modify the emission of events as follows:

2. Capture Form Data

Next, define a local data model within your modal to hold the form inputs. Bind your form controls to this data model using v-model:

Bind the form controls in your modal template to these properties using the v-model directive:

Repeat this for each form field to ensure they're all wired to formData.

3. Emit the Form Data

Next, create a submit function to emit the form data back to the parent component when the form is submitted. Here's how you do that:

4. Modify the Submit Button

You should connect the submit function to the button in the footer of your modal. You can use the scoped slot pattern to achieve that:

This allows the button to call the submit function when clicked.

5. Handle Submission in the Parent Component

Now, in your parent component where the modal is used, modify the submitHandler function to accept the data from the modal:

Conclusion

With these enhancements, your modal becomes a powerful user interface element capable of dynamic data interaction!

Final Thoughts

Don’t forget to test your implementation thoroughly to ensure everything functions as expected. If you encounter issues, double-check the bindings and event emissions as they are crucial for the data flow in your component architecture.
