Bootstrap Modal Window In Angular Using Typescript

Hello, happy to see you here!  

In this blog, you’ll be learning the basic implementation of modal window/popup in Angular using Typescript.

Angular 2/4 or Typescript are bringing in the true Object Oriented Front-end development. First, we can start with Typescript,

What is Typescript?

Typescript is a programming language that is the syntactical superset of Javascript. Typescript being purely object-oriented and helps us to write clean and scalable javascript. When we are developing complex applications many developers find it difficult to write clean and object-oriented code in JS but with Typescript it becomes easy. Typescript also provides tools like advanced autocompletion, navigation, and refactoring. And angular is also written in Typescript because of the features typescript offers.

In Bootstrap we have so many features that are implemented by default, One such feature is modal popup/ modal windows.

Basic Structure of  Bootstrap Model in Angular

 

Angular 2 or 4 is a component-based framework with typescript, Components are major building blocks of it. A component can be defined as an independent cohesive block of code which has the required logic, view, and data as one unit. When written using TypeScript, a component is a TypeScript class decorated with @Component() decorator.

Now let us implement the above bootstrap modal window code in angular.

 

 

Next the model window code is implemented as the following :

 

ngClass or ngStyle are the built-in directives for angular, using them we will be able to dynamically update the HTML element. Now we have used ngStyle to show & hide the modal window.

 

 Display is a defined variable in angular typescript and by default it is none.

 

Next, For opening the model window, click the open modal() and change the display variable value as block.

 

Same as close the model window,

 

Finally, we have a nice backdrop to add to the CSS component.

 

 

Result :

 

And now the modal popup/ modal window will look like the following :
