Navigating without Page Refresh: Resolving Form Button Click Issues
When working with forms in Angular, it's common to encounter unexpected behavior when clicking non-submit buttons within the form. In some cases, the page may refresh, causing undesired consequences. This article explores the reason behind this behavior and provides solutions to prevent unwanted page refreshes.
The issue occurs because form elements are typically designed to submit the entire form when clicked unless explicitly configured otherwise. In Angular, this behavior is triggered by an implicit 'submit' event on button elements without a specified 'type' attribute or when an 'ng-click' event is applied to a button.
Consider the following example:
<form class="form-horizontal"> <button>
When the "Change" button is clicked with the 'ng-click' event, Angular executes the 'showChangePassword()' function, but the default form submission behavior remains intact, causing the page to refresh.
To prevent this behavior, one solution is to assign the 'type' attribute to 'button':
<form class="form-horizontal"> <button>
By specifying 'type="button"', we explicitly indicate that this button should not trigger a form submission. This prevents Angular from initiating the default submit action and allows the custom 'ng-click' event to execute without reloading the page.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
