<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.
