我正在尝试Google在 https:/中提供的示例代码/www.polymer-project/1.0/start/first-element/intro .
I am trying out sample code provided by Google at www.polymer-project/1.0/start/first-element/intro.
这是我到目前为止所拥有的:
This is what I have so far:
index.html:
index.html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport"> <script src="polygit/components/webcomponentsjs/webcomponents-lite.js"></script> <link href="/my_components/icon-toggle-demo.html" rel="import"> </head> <body> <icon-toggle-demo toggle-icon="star"></icon-toggle-demo> </body> </html>icon-toggle-demo.html:
icon-toggle-demo.html:
<link rel="import" href="polygit/components/polymer/polymer.html"> <link rel="import" href="polygit/components/iron-icons/iron-icons.html"> <link rel="import" href="icon-toggle.html"> <dom-module id="icon-toggle-demo"> <template> <style> :host { font-family: sans-serif; }; </style> <h3>Statically-configured icon-toggles</h3> <icon-toggle toggle-icon="star"></icon-toggle> <icon-toggle toggle-icon="star" pressed></icon-toggle> <h3>Data-bound icon-toggle</h3> <!-- use a computed binding to generate the message --> <div><span>[[message(isFav)]]</span></div> <!-- curly brackets ({{}}} allow two-way binding --> <icon-toggle toggle-icon="favorite" pressed="{{isFav}}"></icon-toggle> </template> <script> Polymer({ is: "icon-toggle-demo", message: function(fav) { if (fav) { return "You really like me!"; } else { return "Do you like me?"; } } }); </script> </dom-module>icon-toggle.html:
icon-toggle.html:
<link rel="import" href="polygit/components/polymer/polymer.html"> <link rel="import" href="polygit/components/iron-icon/iron-icon.html"> <dom-module id="icon-toggle"> <template> <style> /* local DOM styles go here */ :host { display: inline-block; } iron-icon { fill: rgba(0,0,0,0); stroke: currentcolor; } :host([pressed]) iron-icon { fill: currentcolor; } </style> <!-- local DOM goes here --> <!-- <span>Not much here yet.</span> --> <!-- <iron-icon icon="polymer"> --> <iron-icon icon="[[toggleIcon]]"> </iron-icon> </template> <script> Polymer({ is: 'icon-toggle', properties: { toggleIcon: String, pressed: { type: Boolean, value: false, notify: true, reflectToAttribute: true } }, listeners: { 'tap': 'toggle' }, toggle: function() { this.pressed = !this.pressed; } }); </script> </dom-module>代码在chrome中工作正常，但在FF中出现以下错误:
The code works fine in chrome but I get following error in FF:
TypeError: document.registerElement is not a function我已经包含了polyfill.还有其他东西吗?
I have already included the polyfill. Something else missing?
推荐答案您没有做错任何事情. index.html文件中的以下行默认为webcomponents polyfill的最新版本(v1.0.0-rc.1).
You're doing nothing wrong. The following line in your index.html file defaults to the newest version (v1.0.0-rc.1) of the webcomponents polyfill.
<script src="polygit/components/webcomponentsjs/webcomponents-lite.js"></script>当前版本的Firefox中似乎存在一个错误.在Polymer文档此处中链接的Plunker中也可以观察到相同的错误. .希望这将由Polymer团队解决.
There appears to be a bug in the current version for Firefox. The same error can also be observed in the Plunker that is linked in the Polymer docs here. This will hopefully be fixed by the Polymer team.
要立即修复，可以显式使用旧版本.例如.
To fix it for now, you can explicitly use an older version. For example.
<script src="cdn.rawgit/webcomponents/webcomponentsjs/v0.7.24/webcomponents-lite.js"></script>更多推荐
