## <iron-jsonp-library>
Loads specified jsonp library.
See: [Documentation](https://www.webcomponents.org/element/@polymer/iron-jsonp-library),
[Demo](https://www.webcomponents.org/element/@polymer/iron-jsonp-library/demo/demo/index.html).
## 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
Library Loaded: [[loaded]]
```
### In a Polymer 3 element
```js
import {PolymerElement, html} from '@polymer/polymer';
import '@polymer/iron-jsonp-library/iron-jsonp-library.js';
class SampleElement extends PolymerElement {
static get template() {
return html`
Library Loaded: [[loaded]]
`;
}
}
customElements.define('sample-element', SampleElement);
```
