library safe_html;import 'dart:async';import "dart:html";import "package:polymer/polymer.dart";@CustomTag("safe-html")class SafeHtml extends PolymerElement { @published String model; NodeValidator nodeValidator; bool get applyAuthorStyles => true; bool isInitialized = false; SafeHtml.created() : super.created() { nodeValidator = new NodeValidatorBuilder() ..allowTextElements(); } void modelChanded(old) { if(isInitialized) { _addFragment(); } } void _addFragment() { var fragment = new DocumentFragment.html(model, validator: nodeValidator); $["container"].nodes ..clear() ..add(fragment); } @override void attached() { super.attached(); Timer.run(() { _addFragment(); isInitialized = true; }); }}<!DOCTYPE html><polymer-element name="safe-html"> <template> <div id="container"></div> </template> <script type="application/dart" src='safe_html.dart'></script></polymer-element>usage:
<safe-html model="{{someField}}></safe-html>
