Issue
I am trying to run the following sample project :
https://github.com/montyr75/pdcl_first_elements
Its working in Chrome and Firefox but not working in IE 11.
In F12 developer tools console it giving this error :
File: index.bootstrap.initialize.dart.js, Line: 1483, Column: 15
I checked IE 11 on browserstack also, same issue.
I am using Eclipse Mars IDE.
So i tried a new project like below :
Pubspec.yaml
name: polymerdartsample
version: 1.0.0
author: tester
description: Sample web application
environment:
sdk: '>=1.12.0 <2.0.0'
documentation: none
dependencies:
polymer: 1.0.0-rc.15
polymer_elements: 1.0.0-rc.8
web_components: 0.12.2+2
transformers:
- polymer:
entry_points: web/index.html
in index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src='packages/web_components/webcomponents-lite.js'></script>
<link rel="import" href="packages/polymer_elements/roboto.html">
<title>Test Data</title>
</head>
<body unresolved>
<main-app></main-app>
<script type="application/dart" src="index.dart"></script>
<script src="packages/browser/dart.js"></script>
</body>
</html>
in index.dart
library polymerdartsample.web.index;
import 'package:polymerdartsample/main_app.dart';
import 'package:polymer/polymer.dart';
import 'dart:html';
main() async {
await initPolymer();
}
in lib/main_app.html :
<dom-module id="main-app">
<template>
<h3>Hello world</h3>
</template>
</dom-module>
in lib/main_app.dart :
@HtmlImport('main_app.html')
library polymerdartsample.lib.main_app;
import 'package:polymer/polymer.dart';
import 'package:web_components/web_components.dart';
@PolymerRegister('main-app')
class MainApp extends PolymerElement {
MainApp.created() : super.created();
}
When I run this I get the same error in IE 11.
please help…
Solution
Use webcomponentsjs instead of webcomponents-lite.js in your index.html, because IE 11 does not support local dom yet ,but you must also know that webcomponents.js is slower than webcomponents-lite.js
