Adding multiple class using ng-class

Adding Multiple Class Using ng-class: A Complete Guide

👋 Hey tech enthusiasts! Are you struggling with adding multiple classes using ng-class in AngularJS? Don't worry, we've got you covered! In this blog post, we'll address common issues and provide you with easy solutions. Let's dive in! 💪

The Challenge

So, you want to add multiple classes using ng-class in AngularJS? Here's an example of what you're trying to achieve:

<div ng-class="{class1: expressionData1, class2: expressionData2}"></div>

The question is: can we have multiple expressions to add these multiple classes? 🤔

The Solution

Yes, indeed! You can add multiple classes using ng-class by combining multiple expressions. Let's break down the example above to understand how it works.

1. First, you'll notice that ng-class is used as an attribute on the HTML element. This allows you to dynamically add or remove classes based on the expressions.

2. Inside the curly braces, you define the classes and their corresponding expressions. In our example, we have two classes: class1 and class2.

3. The expressions, expressionData1 and expressionData2, determine whether the classes should be applied or not. If an expression evaluates to true or truthy, the associated class will be added. Otherwise, it will be removed.

Examples

Here are a few examples to demonstrate how to add multiple classes using ng-class:

Example 1: Using boolean expressions

<div ng-class="{class1: isActive, class2: isError}"></div>

In this example, the class1 will be added if the isActive expression evaluates to true. Similarly, the class2 will be added if the isError expression evaluates to true.

Example 2: Using function calls

<div ng-class="{class1: isClassActive(), class2: isClassError()}"></div>

In this example, the class1 will be added if the isClassActive() function returns true. The class2 will be added if the isClassError() function returns true.
