根据 app-localize-behavior 的 polymer 文档
Each element that displays content to be localized should add Polymer.AppLocalizeBehavior. All of these elements share a common localization cache, so you only need to load translations once.

也许我错过了什么？

但没有它应该可以工作
最佳答案
根据 Jose A. 和 Jean-Rémi 的想法，这里有一些用于复制/粘贴的示例代码:
<link rel="import" href="../bower_components/polymer/polymer.html">
<link rel="import" href="../bower_components/app-localize-behavior/app-localize-behavior.html">
<script>
MyLocalizeBehaviorImpl = {
properties: {
language: {
value: 'de'
}
},
attached: function() {
this.loadResources(this.resolveUrl('locales.json'));
}
};
MyLocalizeBehavior = [MyLocalizeBehaviorImpl, Polymer.AppLocalizeBehavior];
</script>
在所有自定义组件中包含行为文件并添加行为:
<link rel="import" href="./my-localize-behavior.html">
......
behaviors: [
MyLocalizeBehavior
],
