MDCSnackbarFoundation Class usage

问题:

How do I use MDCSnackbarFoundation ? with MDCSnackbar

This documentation is not clear enough to get an idea. https://github.com/material-components/material-components-web/tree/master/packages/mdc-snackbar#using-the-foundation-class

This is my code and I need to bind MDCSnackbarFoundation for it.

logger = new MDCSnackbar($selector[0]);

Thanks

At first you have to have a Node.js server. And then you have to install a package snackbar for Node.js like follows:

npm install @material/snackbar

Responding to a Snackbar Action

To respond to a snackbar action, assign a function to the optional actionHandler property in the object that gets passed to the show method. If you choose to set this property, you must also set the actionText property.

<div class="mdc-snackbar"
     aria-live="assertive"
     aria-atomic="true"
     aria-hidden="true">
  <div class="mdc-snackbar__text"></div>
  <div class="mdc-snackbar__action-wrapper">
    <button type="button" class="mdc-snackbar__action-button"></button>
  </div>
</div>

import {MDCSnackbar} from '@material/snackbar';
​
const snackbar = new MDCSnackbar(document.querySelector('.mdc-snackbar'));
const dataObj =
{
    message: 'The text message to display.',
    actionText: 'Take action',
    //The function to execute when the action is clicked.
    actionHandler: function()
    {
        console.log('my cool function');
    }
};
​
snackbar.show(dataObj);

Before you start with Node.js I would recommend to read one from two books:

• Learning Node: Moving to the Server-Side
• Node.js Web Development: Server-side development
