<iron-jsonp-library>

Loads specified jsonp library.

See: Documentation, Demo.

Polymer.IronJsonpLibraryBehavior

Polymer.IronJsonpLibraryBehavior loads a jsonp library. Multiple components can request same library, only one copy will load.

Some libraries require a specific global function be defined. If this is the case, specify the callbackName property.

You should use an HTML Import to load library dependencies when possible instead of using this element.

Usage

Installation

npm install --save @polymer/iron-jsonp-library

In an html file

<html>
  <head>
    <script type="module">
      import '@polymer/polymer/lib/elements/dom-bind.js';
      import '@polymer/iron-jsonp-library/iron-jsonp-library.js';
    </script>
  </head>
  <body>
    <dom-bind>
      <template>
        <iron-jsonp-library
            library-url="https://apis.google.com/js/plusone.js?onload=%%callback%%"
            notify-event="api-load"
            library-loaded="{{loaded}}">
        </iron-jsonp-library>
        <span>Library Loaded: [[loaded]]</span>
      </template>
    </dom-bind>
  </body>
</html>

In a Polymer 3 element

import {PolymerElement, html} from '@polymer/polymer';
import '@polymer/iron-jsonp-library/iron-jsonp-library.js';

class SampleElement extends PolymerElement {
  static get template() {
    return html`
      <iron-jsonp-library
            library-url="https://apis.google.com/js/plusone.js?onload=%%callback%%"
            notify-event="api-load"
            library-loaded="{{loaded}}">
        </iron-jsonp-library>
        <span>Library Loaded: [[loaded]]</span>
    `;
  }
}
customElements.define('sample-element', SampleElement);
