问:我怎样才能反映出变化=" _toggle"跨所有元素的功能?
我的代码:
1
<script>
LanguageBehavior = {
behaviors: [
Polymer.AppLocalizeBehavior
],
properties: {
language: {
value: 'sl',
reflectToAttribute: true
},
},
attached: function() {
this.loadResources(this.resolveUrl('/data/locales.json'));
},
_toggle: function() {
this.language = this.$.switch.checked ? 'en' : 'sl';
// This function is the problem?
}
};
</script>

<link rel="import" href="../../bower_components/paper-toggle-button/paper-toggle-button.html">
<link rel="import" href="../../bower_components/app-localize-behavior/app-localize-behavior.html">
<link rel="import" href="behavior.html">
<dom-module id="bazdara-element-1">
<template>
<style>
:host {
display: block;
}
</style>
{{localize('menu_2')}} // THIS CHANGES WITH THE SWITCH
<span title="english"> SI</span>
<paper-toggle-button on-change="_toggle" id="switch"></paper-toggle-button>
<span title="french">EN</span>
</template>
<script>
Polymer({
is: 'bazdara-element-1',
behaviors: [Polymer.AppLocalizeBehavior, LanguageBehavior],
});
</script>
</dom-module>
