How to Prevent Unwanted Page Refreshes When Clicking Buttons in Forms?

Preventing Page Refresh on Button Click in Forms

When using buttons within a form, it's essential to avoid accidental page refreshes that disrupt user flow. This issue can arise when buttons are used to trigger functions without submitting the form.

In the provided code example:

The issue is caused by the default behavior of buttons, which is to submit the form. When the button is clicked, the form is submitted, resulting in a page refresh. To prevent this unwanted refresh, the following modification can be made:

Add type="button" to the Button

By adding type="button", the button's default submit behavior is overridden, and it no longer initiates form submission. Instead, it simply executes the specified getData() function without causing a page refresh.

Why Use type="button"?

By default, buttons within a form have a type of "submit," which means they trigger the form's submission when clicked. The type="button" attribute removes this default behavior and makes the button act as a custom button that calls the desired function without any form submission.
