When making an HTTP request to the backend in my project, I need the ability to sort of "freeze" the screen until the request is complete. Specifically, I want to prevent users from being able to interact with certain elements on the page, such as a button that would normally redirect them to another page. Is there a way to accomplish this in Angular?
One common technique is to create a transparent or semi-transparent overlay div along with a spinner, which can be displayed on top of all other elements to prevent user interactions while requests are being made. This overlay can be easily shown or hidden based on request status. There are many libraries and examples available that demonstrate how to achieve this effect. Below is a CSS snippet that shows an example of how the CSS for the overlay could look:
.overlay {
position: fixed;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
z-index: 10000;
opacity: 0.5;
}
And in the template:
<div class="overlay" *ngIf="requestInProgress">
</div>
