angularjsHow do I use the ng-if directive in AngularJS?

The ng-if directive in AngularJS is used to conditionally render an element based on a boolean expression. It is a better alternative to using the ng-show and ng-hide directives as it completely removes the element from the DOM instead of just hiding it.

Here is an example of how to use the ng-if directive:

<div ng-if="user.isAdmin">
  <h2>Welcome Admin!</h2>

In the example above, the <div> element will only be rendered if the user.isAdmin expression is true.

Code explanation

  • ng-if - This is the directive that is used to conditionally render an element.
  • user.isAdmin - This is the boolean expression that is evaluated to determine if the element should be rendered.
