JSPM – @polymer/paper-toast@3.0.1

Package Exports

@polymer/paper-toast
@polymer/paper-toast/paper-toast
@polymer/paper-toast/paper-toast.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@polymer/paper-toast) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

<paper-toast>

paper-toast provides a subtle notification toast. Only one paper-toast will be visible on screen.

Use opened to show the toast:

Example:

<paper-toast text="Hello world!" opened></paper-toast>

Also open() or show() can be used to show the toast:

Example:

<paper-button on-click="openToast">Open Toast</paper-button>
<paper-toast id="toast" text="Hello world!"></paper-toast>

...

openToast: function() {
  this.$.toast.open();
}

Set duration to 0, a negative number or Infinity to persist the toast on screen:

Example:

<paper-toast text="Terms and conditions" opened duration="0">
  <a href="#">Show more</a>
</paper-toast>

<paper-toast> is affected by the stacking context of its container. Adding <paper-toast> inside elements that create a new stacking context - e.g. <app-drawer>, <app-layout> or <iron-list> - might result in toasts partially obstructed or clipped. Add <paper-toast> to the top level (<body>) element, outside the structure, e.g.:

  <!-- ... -->
  </app-drawer-layout>
  <paper-toast id="toast"></paper-toast>
</template>

You can then use custom events to communicate with it from within child components, using addEventListener and dispatchEvent.

Styling

The following custom properties and mixins are available for styling:

Custom property	Description	Default
`--paper-toast-background-color`	The paper-toast background-color	`#323232`
`--paper-toast-color`	The paper-toast color	`#f1f1f1`

This element applies the mixin --paper-font-common-base but does not import paper-styles/typography.html. In order to apply the Roboto font to this element, make sure you've imported paper-styles/typography.html.

See: Documentation, Demo.
