Exploring the Use of Enums in AngularJS HTML Tags

One of my challenges involves using an Enum in typescript:

 enum EnumCountries{
     Canada=0,
     USA=1,
     Holland=2
} 

When working in AngularJS, I encountered some difficulties incorporating it into the HTML. For example, this code snippet did not give the desired outcome:

 <div ng-show="model.country==EnumCountries.USA">

I am striving to eliminate the use of "magic numbers" within the HTML.

Answer №1

To implement Enum in HTML, it is important to declare Enum as a variable

For example, in the component.ts file:

enumOptions = EnumOptions;

Then, in the component.html file, you can use:

<div ng-show="model.option == enumOptions.YES">
