ons-toast

The Toast or Snackbar component is useful for displaying dismissable information or simple actions at (normally) the bottom of the page. This component does not block user input, allowing the app to continue its flow. For simple toasts, consider ons.notification.toast instead.

Tutorial

Toasts

Toasts are defined using the <ons-toast> tag. In Material Design they are also called Snackbars.

<ons-toast id="dialog-1">
  This is a toast!
</ons-toast>

They can be located inside templates or separated files and be created with ons.createElement as any other dialog.

Toasts are hidden by default and usually attached as direct children of the <body> tag.

Displaying a toast

To display a toast you need to get a reference to the element and execute the show(options) method.

document
  .querySelector('ons-toast')
  .show();

It is hidden with the hide(options) method.

Toasts can be toggled with the toggle(options) method.

Notification

Another way to display toasts is with the ons.notification, which returns a Promise. Unlike the previous version, all the toasts created with this method will be part of a notification queue, being visible only one at a time. The force option disables this feature.

ons.notification.toast('Hello ' + name, { timeout: 2000 }); // Shows from 0s to 2s
ons.notification.toast('Good-bye ' + name, { timeout: 1000 }); // Shows from 2s to 3s

Attributes are added directly to the element. You can do this in HTML or JS.

HTML: <ons-toast someAttribute="true" anotherAttribute><ons-toast>
JS: document.querySelector('ons-toast').setAttribute('someAttribute', 'true')

Name Type Description
animation String
default
The animation used when showing and hiding the toast. Can be either "default", "ascend" (Android), "lift" (iOS), "fall", "fade" or "none". Optional.
animation-options Expression Specify the animation’s duration, timing and delay with an object literal. E.g. {duration: 0.2, delay: 1, timing: 'ease-in'}. Optional.
visible Boolean Whether the toast is visible or not. Optional.

Properties are accessed on the element through JS, and should be get and set directly. For example: document.querySelector('ons-toast').animationOptions.

Name Description
animationOptions Specify the animation’s duration, timing and delay with an object literal. E.g. {duration: 0.2, delay: 1, timing: 'ease-in'}.
onDeviceBackButton Back-button handler.
visible Whether the element is visible or not.

To use these events, add event listeners to the elements as you would for native events, like click. For example: document.querySelector('ons-toast').addEventListener('preshow', function() { ... }).

Some Onsen UI components have overlapping event names. For example, ons-carousel and ons-navigator both emit postchange events. Stop overlapping events from propagating to avoid conflicts: document.querySelector('ons-carousel').on('postchange', e => e.stopPropagation()).

Name Description
preshow Fired just before the toast is displayed.
postshow Fired just after the toast is displayed.
prehide Fired just before the toast is hidden.
posthide Fired just after the toast is hidden.
preshow

Parameters

event.cancel Function Execute to stop the toast from showing.
