I'm attempting to apply a class conditionally to an element, but I'm struggling with the correct syntax.
I've experimented with the code below, but it's not functioning as expected:
ng-class="{foo: bar === "true"}"
The value of bar is boolean.
Additionally, the element already has a class attribute. Will adding foo append it to the existing list of classes?
A suggestion would be to avoid using double quotes in your evaluation, as it may prematurely close your ng-class attribute. Instead, consider using single quotes when checking a string value. If 'bar' is a boolean value in your scenario, there is no need for any quotes:
ng-class="{foo: bar === true}"
This is the same as:
ng-class="{foo: bar}"
For strings, you can use:
ng-class="{foo: bar === 'your_string'}"
If your element already has a class attribute, 'foo' will be added to the existing list.
ng-class="{'highlighted': isActive}
