问题 I am learning about angular.dart components by trying to make one that will access an existing jquery plugin.

Here is a clip from the documentation: elements.html <polymer-element name="app-globals"> <script> (function() { var values = {}; Polymer({ ready: function() { this.values = values; for (var i = 0; i <

问题 This questions is similar to some other on StackOverflow, but I couldn't find any answer describing applicable to my situation and non-deprecated method (and I'm starting thinking that maybe there is no any good solution for that situation).
