Usage

1. Initialize the plugin by referencing the necessary files:

You can also include the stylesheet separately if desired:

<script src="sweetalert2.min.js"></script>
<link rel="stylesheet" href="sweetalert2.min.css">

Or

// ES6 Modules or TypeScript
import Swal from 'sweetalert2'

// CommonJS
const Swal = require('sweetalert2')

It's possible to import JS and CSS separately, e.g. if you need to customize styles:

import Swal from 'sweetalert2/dist/sweetalert2.js'

import 'sweetalert2/src/sweetalert2.scss'

2. Call the sweetAlert2-function after the page has loaded

Swal.fire({
  title: 'Error!',
  text: 'Do you want to continue',
  icon: 'error',
  confirmButtonText: 'Cool'
})

You can easily reuse configuration by creating your own Swal with Swal.mixin({ ...options }):

Declarative templates and declarative triggering

There's also the declarative way to define a popup, via the <template> tag. This is handy when you want to define popup on server side (SSR).

Supported template elements:

<swal-title>...</swal-title>
<swal-html>...</swal-html>
<swal-footer>...</swal-footer>

<swal-param name="..." value="..." />
<swal-function-param name="..." value="..." />

<swal-button type="..." color="..." aria-label="...">...</swal-button>
<swal-image src="..." width="..." height="..." alt="..." />
<swal-icon type="..." color="...">...</swal-icon>
<swal-input type="..." label="..." placeholder="..." value="..." />
<swal-input-option value="...">...</swal-input-option>

And you can even trigger SweetAlert2 popups declaratively! Use the bindClickHandler() method for that:

Handling Buttons (Confirm, Deny, Cancel)

When the user clicks a button, the Promise returned by Swal.fire() will be resolved with the SweetAlertResult object:

Key Description
isConfirmed The "Confirm" button was clicked, the value will contain the result
isDenied The "Deny" button was clicked, the value will be false.
Alternatively, if there's an input in a popup, you can use returnInputValueOnDeny: true to return the input's value.
isDismissed The "Cancel" button was clicked, the dismiss will be Swal.DismissReason.cancel
value The value from the popup, possible values:
  • true for simple confirmed dialogs
  • false for denied popups
  • any value for popups with inputs
dismiss The dismissal reason, see the Handling Dismissals section for details

Handling Dismissals

When an alert is dismissed by the user, the Promise returned by Swal.fire() will be resolved with an object { isDismissed: true, dismiss: reason } documenting the reason it was dismissed:

Reason Description Related configuration

Swal.DismissReason.backdrop

The user clicked the backdrop. allowOutsideClick

Swal.DismissReason.cancel

The user clicked the cancel button. showCancelButton

Swal.DismissReason.close

The user clicked the close button. showCloseButton

Swal.DismissReason.esc

The user clicked the Esc key. allowEscapeKey

Swal.DismissReason.timer

The timer ran out, and the alert closed automatically. timer

If a popup is dismissed by Swal.close(), the Promise will be resolved with an object { isDismissed: true } (dismiss will be undefined).

    '<input id="swal-input1" class="swal2-input">' +
    '<input id="swal-input2" class="swal2-input">',

      document.getElementById('swal-input2').value
    ]
  }
})

if (formValues) {
  Swal.fire(JSON.stringify(formValues))
}
