IronFormElementBehavior

IronFormElementBehavior adds a name, value and required properties to a custom element. This element is deprecated, and only exists for back compatibility with Polymer 1.x (where iron-form was a type extension), and it is not something you want to use. No contributions or fixes will be accepted.

See: Documentation.

Usage

Installation

npm install --save @polymer/iron-form-element-behavior

In a Polymer 3 element

import {PolymerElement, html} from '@polymer/polymer';
import {mixinBehaviors} from '@polymer/polymer/lib/legacy/class.js';
import {IronFormElementBehavior} from '@polymer/iron-form-element-behavior/iron-form-element-behavior.js';

class SampleElement extends mixinBehaviors([IronFormElementBehavior], PolymerElement) {
  static get template() {
    return html`
      <style>
        :host {
          display: block;
        }
      </style>
      <input name="[[name]]" value="{{value}}">
    `;
  }
}
customElements.define('sample-element', SampleElement);
