How to use Alertify JS?#

To use Alertify JS, you first need to include the library in your HTML file. You can download the library from the official website or include it from a CDN:

<head>
  <!-- Alertify JS -->
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/alertifyjs@1.13.1/dist/css/alertify.min.css" />

// Show an alert dialog
alertify.alert('Hello World!');

// Show a confirm dialog
alertify.confirm('Are you sure?', function(){
  alertify.success('Confirmed!');
}, function(){
  alertify.error('Cancelled!');
});

// Show a prompt dialog
alertify.prompt('Please enter your name:', function(val, ev){
  // The user clicked "OK"
  ev.preventDefault();
  alertify.success('You entered: ' + val);
}, function(ev){
  // The user clicked "Cancel"
  ev.preventDefault();
  alertify.error('Cancelled!');
});

As you can see, Alertify JS provides a simple and intuitive API for creating dialogs in your web applications.

Customizing Alertify JS#

Alertify JS comes with built-in themes and customization options that allow you to customize the look and feel of your dialogs. You can customize the following aspects of the dialogs:

• Text and button colors
• Background colors
• Button labels and icons
• Dialog size
• Animation effects

You can customize Alertify JS by creating your own CSS styles or by using one of the built-in themes. Here is an example of how to use a built-in theme:

<head>
  <!-- Alertify JS -->
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/alertifyjs@1.13.1/dist/css/alertify.min.css" />
  
  <!-- Alertify JS theme -->
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/alertifyjs@1.13.1/dist/css/themes/default.min.css" />
  
  <script src="https://cdn.jsdelivr.net/npm/alertifyjs@1.13.1/dist/alertify.min.js"></script>
</head>

By including the theme CSS file after the main CSS file, you can apply a different theme to your dialogs.
