The cli will add the component to the same folder as the module. Also, make sure that the dialog component is declared in the dialog module instead of the app module. We will learn how to create dynamic components and attach them to the DOM or use them in other components. AngularJS provides built-in services on top of XHR as well as various other backends using third party libraries. Promises further simplify your code by handling asynchronous return of data. HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications. AngularJS lets you extend HTML vocabulary for your application.
Let us change the locale by using in the provider in AppModule. However, binding to the style property looks slightly different from other property bindings. This is because the style property is an object itself, with the CSS properties as its properties. Therefore, we also need to specify the actual CSS property to style. Now, let us look at how to dynamically change inline styles in Angular. We often need to change these values while the application is running based on some interaction or some logic. For example, highlight products on sale by changing the background colour of the elements that display those products.
In a complex application, there may be many modules, each with its own distinct i18n data. A naive approach, such as loading and providing i18n data all at once, should therefore be avoided. The package being installed will provide all the supporting features to make the implementation of internationalization easier. It provides a predefined set of constants to define your locale and also some standard methods to format the text like date and time.
Internationalization Of Angularjs Applications
We create the most advanced marketplace solution integrated with AI to power your online store. Making statements based on opinion; back them up with references or personal experience. Once step 4 is complete, we need to have the drop-down with the list of languages to select from.
Most of the languages around the world are written from left to right. However, even today there are several languages that are written and read right to left. This necessitates that the internationalization process supports the facility to display the characters in either of these directions. Simple to use Angular.js service & filter to be able to switch locale dynamically, with no need to do a full page refresh. When I change the locale $localeChangeSuccess event is broadcated from $rootScope and this event is never catched by the code (I’ve added an alert). But unfortunately, my problem is using datepicker popup, and I’m not so familiar with source code about ui.bootstrap. That’s what’s exactly the directive I was searching for, I’m not sure but I think it’s lighter that the ng-show/ng-hide way, at least we don’t have useless DOM elements.
Element was never hidden in the first place, so it was supposed to show by default. I tried taking out .show() and the app was still running fine. I used another approach with keeping logic in Software configuration management the controller… I used an ng-include with its src that is bound to a property in the controller. First, I get the appropriate template and add it to the DOM via element.html() and then show().
Run Application
We are passing in the injector we requested in the constructor. This enables the dynamic component to make use of dependency Scrum (software development) injection itself. Because this is the default configuration now, we are using AOT for this tutorial exclusively.
- APIs may not be able to handle strings with variables or strings that rely on message format.
- The service tmhDynamicLocale provides has one method set to change the locale.
- Before building the application, we need to configure the application to utilize the files that we have created.

Best practice is to create a directory where every content that needs localization is located e.g. ./locale. Now copy your generated file into the new folder and include the locale information into the filename. For example, messages.en.xlfif the content is English ormessages.de.xlfif it’s German content. First, we will take a closer look at the built-in tools of Angular. We will show you how to set up your Angular localization and how to actually translate content.
Template Expression Context
Ngx-translate can’t export your content automatically. But there is a plugin that can extract every translatable content and save it as JSON or Gettext pot files. Here, you have to tell the app what the default language should be. The default language will be used in cases where no translation in the target language exists.
Where this approach would fall apart is if you had a LOT of variations you needed to account for. What would happen if you had 40 different content types you needed to render? That would very quickly become unmanageable and we are back to the jQuery DOM spaghetti problem of yesteryear. Software construction What if you needed to dynamically compose a single DOM structure from multiple templates depending on rules set forth by business logic. The DOM would not be an appropriate place to make those decisions. But just wanted to share another way of going about changing views on the fly.

Instead of creating a new directive, however, I opted for a more simple approach using ng-switch . I’m not sure what the performance difference is, but I prefer ng-switch because it keeps all HTML within the template. AngularJS is a super powerful framework for building great applications but I love it when I figure out ways to bring the fashion to the functionality. The attributei18nwill take care of the localization of this content.
This is done quite similar to how we dynamically created the DialogComponent. Except that we now don’t want to place our component inside the HTML-Body but in a certain place in our DialogComponent.

Angular Localization And Internationalization
Just like ngStyle, we can apply styling directly to the host element. Again, inline styling is not a recommended way to write styles, but sometimes it’s needed.
For instance, use a specific template if the user is logged in or not and another template based on the user’s status and so on. Also, dynamic locale in angularjs you will discover how to provide objects to these dynamic components using dependency injection and custom angular injectors.
