How to Show a Loading Spinner Next to the Clicked Row in Angular

When working on web applications, providing feedback to users through loading spinners helps enhance the user experience, especially when processing data. In this guide, we will address a common scenario – how to display a loading spinner next to the clicked row in an Angular application while avoiding the issue of the spinner appearing on every row.

The Problem

Imagine you have a selection list where users can click on a row to perform an action, like loading data related to that item. However, your spinner is currently displaying on every row whenever any of them are clicked. This can create confusion for users as they may not know which row is being processed.

The Solution

To resolve this issue, we will implement a mechanism that shows the loading spinner only next to the row that the user clicked on. We will achieve this by following these structured steps:

Step 1: Initialize Selected Month

First, we need to create a variable that holds the currently selected month. You can declare a variable called selectedMonth in your component class and initialize it as an empty string:

Step 2: Update the Click Event

Update your existing click event handler to set the selectedMonth to the month when a row is clicked. Here is an example of how to implement this in the selectedDate(month) function:

Step 3: Modify the HTML to Show the Spinner Conditionally

Next, we modify the HTML to ensure that the spinner is only displayed next to the row that matches the selectedMonth. You'll want to use Angular's *ngIf directive for this purpose.

Here’s how you can structure your HTML code:

Summary

By following these steps, we have successfully ensured that the loading spinner displays only next to the row that is clicked by the user, enhancing clarity and user interaction. This method leverages simple Angular features like variables, events, and structural directives to provide an intuitive interface.

Now you can implement this in your Angular project and improve your user experience with a neat loading indicator! If you have further questions, feel free to ask.
