AdminLTE 3 is a popular, open-source admin dashboard and control panel theme for web applications. One of its key features is the ability to display toasts, which are notifications or alerts that pop up on the screen.
The purpose of toasts is to provide a quick and efficient way to let users know about events, such as errors or success messages. This is especially important in web applications, where users are often interacting with the app through asynchronous requests that don't require a page refresh.
To use toasts in your AdminLTE 3-powered web application, you'll need to include the required JavaScript and CSS files. You can do this by adding the following code in your HTML file's <head> element:
<!-- REQUIRED SCRIPTS -->
<!-- jQuery -->
<script src="plugins/jquery/jquery.min.js"></script>
<!-- Bootstrap 4 -->
<script src="plugins/bootstrap/js/bootstrap.bundle.min.js"></script>
<!-- AdminLTE App -->
<script src="dist/js/adminlte.min.js"></script>
And the CSS code:
<!-- REQUIRED STYLE -->
<!-- Font Awesome -->
<link rel="stylesheet" href="plugins/fontawesome-free/css/all.min.css">
<!-- Theme style -->
<link rel="stylesheet" href="dist/css/adminlte.min.css">
Once you have included these files, you can start using toasts. To display a toast, you can use the toastr object, which is provided by AdminLTE 3.
Here's an example of how to show a success toast:
toastr.success('Your request has been completed successfully.', 'Success')
And an error toast:
toastr.error("Oops! There was an error processing your request.", 'Error')
You can also customize the appearance and behavior of the toasts by passing options to the toastr function. For example, to set the toasts to appear at the top-right corner of the screen, you can use the following code:
toastr.options = {
positionClass: 'toast-top-right'
}
AdminLTE 3 toasts are a powerful and flexible tool for displaying notifications and alerts in web applications. By including the required JavaScript and CSS files, and using the toastr object, you can quickly and easily add toasts to your web app.
