Displaying multiple lines in an alert box using Angular 8

Question

Displaying multiple lines in an alert box using Angular 8

I need assistance in displaying an alert message when the user selects a checkbox. We have a shared alert service component that is being utilized by every module.

My current code snippet is as follows:

     if(this.checkboxvalue)
      {
        this.alertservice.error('Hello again! This is how we add line breaks to an alert box!')
      }

The desired format for the alert message is:

Hello again! This is how we add
line breaks to an alert box!

However, the message is currently displayed in a single line.

I have attempted using \n, \\n ,<br\> without success.

If anyone can provide guidance on achieving the desired formatting, it would be greatly appreciated.

Thank you in advance :)

Ensure you are using <br/> instead of <br\>:

alert = "Hey there! Remember to use<br/>for line breaks in your message!"

This approach resolved the issue for me. Feel free to reach out if you require a stackblitz demonstration.

It appears that the way you are trying to display your error in the template is like this:

{myError}

However, Angular automatically filters the content of {myError} for security purposes. You can learn more about this behavior here: https://angular.io/guide/security#sanitization-and-security-contexts
