= "settingscontroller1 as Settings" One way to inject $ scope into the controller: NG-controller = "settingscontroller2" the second choice is more common in the angular community. It is generally used for templates and guides. However, property controllers are directly bound to avoid range. When multiple controllers control elements with the same name, use controller as to make your template more obvious. If you are writing your controller class, it

. You need to use the templateurl attribute. template usage is complicated and will be explained in the next article. If neither template nor templateurl is specified, this command does not modify or replace the content of the command element. for example, angular learning notes (19th)-command to modify dom Let's take a look at the demo: HTML: JS: /* 20.1 command */var dirappmodule = Angular. module ('dir

@ngrx/store builds on the concepts made popular by Redux and supercharges it with the backing of RxJS. The result is a tool and philosophy, that'll transform the the-the-approach state management in your Angular 2 applicatio Ns.

Yesterday we also talked about the way angular introduces complex JSON files, and today we're going to learn one more way, and it's simpler and faster.First we introduce a angular plug-in, and write on the introduction of modules and consoles, in HTML to write the module name and console name.Then create a JSON fileThen we need to introduce this JSON file into the consoleWe then export the data in the JSON

Angular 2 Form form In the Angular2 form form we need to understand the form data binding, data validation, data submission and so on, in the following example is not actually submitted to the background, this part of the content in the future Webapi to practice.

Let's say you want-to-write a simple data-bing app. When your type in a text box, somewhere in the application would show th E result.In Angular 1, you can use Ng-model to finish all those stuff, but Angular 2, the concept behind have changed.index.html -HTML>Head> title>Angular

Two-way binding still exists in Angular 2 and Ng-model makes it simple. The syntax is a combination of the [input] and (output) syntax to represent, the data is being pushed out and pulled I N.Import {Component} from ' Angular2/core './todoservice '; @Component ( {' todo-input ', Template: ' [(Ngmodel)]= "Todomodule"> '}) Export class todoinput{ todomodule:string; Constructor (

This lesson discusses if and how to add dependencies, resolved by Angular ' s DI, to factory providers. The example used in this lesson builts upon the previous lesson on understanding factory providers.For example, the Loggerprovider need-to-use Consoleservice, as-you-put loggerprovider into ' providers ' array, we also Need to provide dependence which refer to Consoleservice, the "Do"providers: [ todoservice, consoleservice, , { = =
