How should one go about properly implementing the ng2 sequence to refresh a component display based on a dropdown selection?

How can I properly refresh a component's display in ng2 based on dropdown selection? Within my application, there is a users.component and a users.service responsible for searching for users based on a provided request object.

Within the users component html template, we have a Region dropdown. When a site user selects a region from the dropdown, the component should display a list of users belonging to that selected region.

What is the correct method for passing the request object to the users.service? The users.service should not create the request object but rather accept it. In traditional JavaScript, I would typically bind to the click event of the dropdown to call a function like refreshDisplay(), which then retrieves the selected value, constructs a request object, and initiates an AJAX call using the request object.

Answer №1

When working with traditional JavaScript, I typically bind to the click event of a dropdown in order to trigger a refreshDisplay() function. This function retrieves the selected value, constructs a request object, and then initiates an ajax call with that request object.

With Angular, you'll follow a similar approach, but instead of directly handling browser events, you'll leverage Angular's abstraction:

<select (change)="someMethod()">
...options
</select>
