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>
</div>
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.
