Alert widget

Overview

The Magento alert widget implements a modal pop-up window with a confirmation button. It extends the Magento modal widget.

The alert widget source is <Magento_Ui_module_dir>/view/base/web/js/modal/alert.js

The widget can be used for implementing alert windows for both Admin and storefront . The design patterns for the pop-up modal windows in the Admin are described in the Magento Admin Pattern Library, the Slide-out Panels, Modal Windows, and Overlays topic.

Initialize the alert widget

The alert widget can be initialized with or without binding to a certain element.

Example1: initialization on an element

$('#init_element').alert({
    title: 'Warning',
    content: 'Warning content',
    actions: {
        always: function(){}
    }
});

Example2: standalone initialization

require([
    'Magento_Ui/js/modal/alert'
], function(alert) { // Variable that represents the `alert` function
 
    alert({
        title: 'Some title',
        content: 'Some content',
        actions: {
            always: function(){}
        }
    });
 
});

For details about how to initialize a widget in a.phtml template, refer to the JavaScript initialization topic.
