javascript Correct use for angular-translate in controllers

We encourage everyone to have a look at our documentation website. If you think the documentation is not correct or should be optimized please file an issue. The asynchronous nature of the loading causes the problem.

• Angular JS provides users with the framework to create web applications.
• This is my preferred way since I don’t have to handle promises this way.
• Most of the time, we are getting support questions of invalid configurations.

Some familiarity with setting up an Angular project. While Angular has some built-in i18n functionality, ngx-translate is a third-party package that offers some functionality that might be better suited for your use case.

Using Translation Files

Integrate our Website Translator with angularjs translateJS to create great multilingual web applications. Covering all aspects of angular-translate fills a whole tutorial itself. See the angular-translate tutorial on ng-newsletter for a great introduction to the module.

You can also set the key of the translation as the content of the element. Using the service, there are two methods to get your translations. With that setup, you have three ways to access the translations. Which one you use at any given time will be up to your needs and preferences. Before you can access these translations in your application, you have to initialize some properties in the TranslateService.

You can write your own loader, or import an existing one. For example you can use the TranslateHttpLoader that will load translations from files using HttpClient. Creating the translation loader in this way expects you to have a file in your project under an /assets/i18n/ folder, called .json, where is the language of the file you are using for translations. For English, this file may be en.json, for example. Angular JS provides users with the framework to create web applications.

Test out Translate.com today to find out easy cultivating a global web presence can truly be. Translation data, unlike other dynamic data on the page, must, of course, show up immediately to the user. Since version 2.8.0 there is also $translate.onReady(), which returns a promise that is resolved as soon as translations are ready. The point of translations is that they can change on user preferences or even on user action. So you need, in general, to load them dynamically. At least if the number of strings to translate is important, and / or if you have lot of translations.

When developing large https://forexhero.info/JS applications for a wide audience, internationalization of these apps becomes more and more important. Once you’ve decided which loader to use, you have to setup the TranslateModule to use it. This document shows you how to get the project, run all provided tests and generate a production ready build.

The output of the filter can be directly set to a scope variable. The second time I go to the page, all is well and the translated version is shown. For every application view, there is a dedicated controller. In the controllers below, I set the value to be shown as the page title.

The unit tests are available with npm test which is actually a shortcut for grunt test. It performs tests under the current primary target version of AngularJS. Use npm run-script test-scopes for testing other scoped versions as well.

If your loader is synchronous, just use Observable.of to create an observable from your static value. You can also define your translations manually with setTranslation. I am doing registration page and my app contains English and Arabic pages. I am storing English and Arabic words in JSON files. Most of the time, we are getting support questions of invalid configurations.

If you don’t know in-context editing yet, have a look at our demo. AngularJS is an awesome Javascript framework to build single-page applications with Javascript. We’re huge fans of the framework that was developed and is maintained by the Google team.

With Angular JS, users are able to use HTML as the template language, as well as extend your HTML’s syntax for clear app components. With Angular’s data binding and dependency injection, users are able to minimize the amount of code otherwise required. You can setup a provider for the MissingTranslationHandler in the bootstrap of your application , or in the providers property of a component. It will be called when the requested translation is not available. The only required method is handle where you can do whatever you want. If this method returns a value or an observable , then this will be used.

I assume the issue has to do with the fact that maybe the translation file is not yet loaded when the controller is assigning the value to $scope.pageTitle. The parameter for all of these is the language you want to pull translations from – these should match the names of the JSON files that define the translations for those languages. The translation file is a JSON object of key-value pairs, where the key describes the text that is translated, and the value is the actual text in the language specified by the file. Probably the most common way to load translations is to include your translation files as assets and load them via the TranslateHttpLoader, which is available in a separate npm package. If you’re using an old version of Angular and ngx-translate requires a newer version then you should consider upgrading your application to use the newer angular 2 version. There is always a reason when I upgrade the minimum dependencies of the library.

@Bombinosh I’d say use filter method if you know translations are loaded. Personally I would even recommend not loading translations dynamically if you don’t have to. It’s a mandatory part of your application, so you better don’t want the user to be waiting for it. You can use the translate pipe much like you’d use any other pipe in Angular. The input into the pipe is the key of the translation you need. The optional parameter is an object which defines any interpolation strings that the translation is expecting.

• Why $translate.instant() and not just async $translate()?
• For example you can use the TranslateHttpLoader that will load translations from files using HttpClient.
• With Angular JS, users are able to use HTML as the template language, as well as extend your HTML’s syntax for clear app components.

First, translate.addLangs([]) tells the service which languages are available to use for translations. If you want to write your own loader, you need to create a class that implements TranslateLoader. The only required method is getTranslation that must return an Observable.
