How to Render an HTML Template on Button Click in Angular
As a tech professional working with TypeScript and Angular, you may come across the need to dynamically render an HTML template on a button click. In this blog post, we will explore different solutions to achieve this functionality.
Solution 1: Using *ngIf Directive
One way to render an HTML template on button click is by using the *ngIf directive in Angular. By binding the *ngIf directive to a boolean variable, we can control the visibility of the HTML template.
First, let’s create a button in our component’s HTML template:
Next, we can use the *ngIf directive to conditionally render the HTML template:
This is the rendered HTML template
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Now, when the button is clicked, the value of the showTemplate
variable will be toggled, and the HTML template will be rendered or hidden accordingly.
Solution 2: Using ng-template and TemplateRef
Another approach to render an HTML template on button click is by using the ng-template
directive and TemplateRef
in Angular.
First, let’s define our HTML template using the ng-template
directive:
This is the rendered HTML template
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Next, we need to create a reference to the ng-template
using @ViewChild
decorator in our component:
@ViewChild('template') templateRef: TemplateRef;
Then, we can create a method in our component to toggle the visibility of the HTML template:
showTemplate = false;
toggleTemplate() {
this.showTemplate = !this.showTemplate;
}
Finally, we can use the ng-container
directive along with the ngTemplateOutlet
directive to render the HTML template:
Now, when the button is clicked, the HTML template will be rendered or hidden based on the value of the showTemplate
variable.
These are two different solutions to render an HTML template on button click in Angular. Choose the one that best suits your requirements and implement it in your project.
Happy coding!
