我有错误的document.registerElement underfined [英] I have error document.registerElement underfined
问题描述
JavaScript运行时错误：对象不支持文件中的属性或方法'registerElement'
JavaScript runtime error: Object doesn't support property or method 'registerElement'
：... bower_components\polymer\polymer.js第11701行
in File: ... bower_components\polymer\polymer.js Line 11701
document.registerElement('polymer-element', {prototype: prototype});
我的凉亭：
{
"name": "Polymer",
"version": "0.0.0",
"main": "main",
"license": "MIT",
"private": true,
"dependencies": {
"polymer": "Polymer/polymer#~0.5.2",
"core-icons": "Polymer/core-icons#~0.5.2",
"core-elements": "Polymer/core-elements#~0.5.2",
"paper-elements": "Polymer/paper-elements#~0.5.2"
}
}
和我的页面：
<!DOCTYPE html>
<html>
<head>
<link rel="import" href="/client/polymer-0.5.2/bower_components/polymer/polymer.html">
</head>
<body>
<!-- render data set -->
<template id="auto-bind-demo" is="auto-binding" repeat="{{quotes}}">
<div on-tap="{{quoteClicked}}">
<h3>{{quote}}</h3>
- <em>{{attribution}}</em>
</div>
</template>
<script>
var t = document.querySelector('#auto-bind-demo');
t.quoteClicked = function() {
alert('Quote clicked!');
};
t.quotes = [{
attribution: 'Plautus',
quote: 'Let deeds match words.'
}, {
attribution: 'Groucho Marx',
quote: 'Time flies like an arrow. Fruit flies like a banana.'
}];
</script>
</body>
</html>
怎么了？我从文档中的示例中获取了这个。 https://www.polymer-project.org/docs/ polymer / databinding-advanced.html #autobinding
What's wrong? I took this from the example in the documentation. Here https://www.polymer-project.org/docs/polymer/databinding-advanced.html#autobinding

推荐答案
目前只有Chrome和其他基于blink的浏览器支持自定义元素。 Firefox支持但不支持defualt。
Currently only Chrome and other blink-based browsers support Custom Elements. Firefox supports but not enabled by defualt.
请参阅 我可以使用 获取完整的支持图表。
See Can I Use for a full supporting chart.
如果您在其他浏览器上使用它，则需要包含网页组件 polyfill （通常是名为 webcomponents.js 的文件）。
If you are using it on other browsers, you need to include a Web Components polyfill (usually a file named webcomponents.js).
