IronScrollTargetBehavior

IronScrollTargetBehavior allows an element to respond to scroll events from a designated scroll target.

Elements that consume this behavior can override the _scrollHandler method to add logic on the scroll event.

See: Documentation, Demo.

Usage

Installation

npm install --save @polymer/iron-scroll-target-behavior

In a Polymer 3 element

import {PolymerElement, html} from '@polymer/polymer';
import {mixinBehaviors} from '@polymer/polymer/lib/legacy/class.js';
import {IronScrollTargetBehavior} from '@polymer/iron-scroll-target-behavior/iron-scroll-target-behavior.js';

class SampleElement extends mixinBehaviors(IronScrollTargetBehavior, PolymerElement) {
  static get template() {
    return html`
      <p>Scrollable content here</p>
    `;
  }

  _scrollHandler() {
    console.log('_scrollHandler', this._scrollTop, this._scrollLeft);
  }
}
customElements.define('sample-element', SampleElement);
