這是完全一樣的問題: Localization/Internationalization for Polymer 1.0本地化內的JavaScript
聚合物已下降爲支持i18n(顯然)和已經轉移到使用format.js其應用,本地化行爲的組成部分。到目前爲止,所有示例都使用數據綁定。但我需要通過JavaScript的setAttribute方法設置元素的屬性。我該如何實現這一點?
<dom-module id="pgarena-login">
<template>
<style is="custom-style" include="pgarena-login-styles"></style>
<style>
</style>
<form is="iron-form" method="post" action$="{{action}}" id="login">
<h2>Login</h2>
<paper-input label="Username" required tabindex="0" name="UserName"></paper-input>
<paper-input label="Password" type="password" required tabindex="0" name="Password"></paper-input>
<!-- Anti Forgery Token -->
<content></content>
<paper-button onclick="_submit(event)">Login</paper-button>
</form>
</template>
<script>
function _submit(event) {
Polymer.dom(event).localTarget.parentElement.submit();
}
(function() {
'use strict';
Polymer({
is: 'pgarena-login',
behaviors: [
Polymer.AppLocalizeBehavior
],
ready: function() {
var $this = this;
this.$.login.addEventListener('iron-form-error', function (event) {
console.log(event);
if (event.detail.request.xhr.status === 400) {
Array.prototype.slice.call(Polymer.dom(this.root).querySelectorAll('paper-input'))
.forEach(function(element) {
element.setAttribute("invalid", true);
//Problematic Line here=> element.setAttribute("error-message", $this.localize("Login_Fail_UsernameInvalid"));
});
}
});
this.$.login.addEventListener('iron-form-response', function (event) {
console.log('chapewn');
console.log(event);
console.log(event.detail);
});
},
properties : {
action : {
type: String
}
},
attached: function() {
this.loadResources(this.resolveUrl('../locales.json'));
},
});
})();
</script>
</dom-module>
我還沒有能夠破解它。我嘗試了一切,但仍不知道如何訪問它。 –
