Controlgroup Description: My understanding of the directive is to bind the Controller group in the HTML template, and then operate these corresponding modules inside the component class, to see the code below, a look at it.Our root app Componentimport {Component, View, Control, Controlgroup, ControlArray, validators, Core_directives, Form_directives} from ' Angular2/angular2 ' @Component ({selector: ' My-app ',}) @View ({Template: ' 　　Angular

Property Binding is the Bind property not attribute!Import {Component, Input, Output, eventemitter} from ' Angular2/core '; @Component ({selector:' Hero-item ', Styles: ['. Active {color:red} '], Template: 'class.active]= "IsSelected"[Attr.aria -label]= "Hero.name"(click)= "Selecthero (Hero)" >{{Hero.name}} `})//Export Class heroitem{label= "This is a super hero"; IsSelected=false; @Input () hero; @Output () Changed=NewEventemitter (); Constructor () {} Selecthero (Hero) { This. Changed.em

TypeScript is used heavily as we build to our application, but TypeScript isn ' t required. If you want to Inject a Service without using TypeScript, you'll need to understand the decorator @Inject .Import {Component, View, Inject} from "Angular2/angular2"; Import {Todoservice} from"./todoservice"; @Component ({selector:' Todo-input '})//Define a ref by using XXX-YYY//Reference a ref by using XXXYYY@View ({Template: ' `}) Export class todoinput{ todoservice; Constructor (//Public Todoserv

When creating a service, need to inject the sercive into the bootstrap ():Import {bootstrap, Component, View} from "Angular2/angular2""./todoinput"; "./todoservice" ; @Component ({ selector:' app '}) @View ({ directives: [Todoinput], Template: ' '}) class app{}Bootstrap (APP, [Todoservice]) ;Todoservice.jsExport class todoservice{ = []; Addtodo (value:any):void { this. Todos.push (value); }}Inputtodo.js:Import {Component, View} from "Angular2/angular2"; Imp

RxJS allows combine streams in various ways. This lesson shows do you have a click stream and combine it with a store stream to use a value from the store inside a Reducer.The logic is when we click the Recall button, it'll reset all the people's time to the current time.First, bind the click event to recall$:"recall$.next ()">RecallNew Subject ();We get the latest time from the time Stroe:Constructor (store:store) { This. Time = store.Select('Clock'); This. People = store.Select('people'); Obs

Showing how can expose properties on your controllers to access them using #refs inside of your template.// letterselect.ts ' angular2/angular2 '; @Component ({ ' letter-select '}) @View ({ directives: [Ngfor,form _directives], Template: ' for = "#letter of letters" >{{letter}} '}) Export class Letterselect { = [' E ', ' s ', ' W ']; Selectedletter = ' E '; Constructor () { }}Todolist.tsImport {Component, View, Ngfor, form_directives} from ' Angular2/angular2 ';

Angular's core MVVM, here's a look at the MV (data to view).Execute the above code, we use settimeout delay two seconds to update the data (M), our view (V) has not changed.The data actually changed , but our view (V) didn't refresh in time because the native settimeout didn't have the ability to refresh.Angular provides us with a settimeout service, $timeout, the need to introduce the service in AAA!We bind a click event to an element with ID AAA and change the name value to hi when a click occ

({directives: [Form_directives, Ngif], Template: 'Div> H2>Demo Form:skuH2> Ngform is attched to the form, and #f = "form" form was also come from Ngform - form[Ng-form-model]= "MyForm"(Submit)= "OnSubmit (myform.value)"> Divclass= "Form-group"[Class.has-error]= "!sku.valid sku.touched"> label for= "Skuinput">Skulabel> inputtype= "text"class= "Form-control"ID= "Skuinput"placeholder= "SKU"[Ng-form-control]= "myform.controls[' sku ')">

In this lesson, we discuss how and if to use factory providers, to enable dependencies that shouldn ' t is available to an Gular ' s DI.If you have the This service:class Loggerprovider { Constructor (Enabled:boolean) { if(enabled) { Console.log ( " Logger is enabled " ) } }}which requires you provide Param in constructor function.If you just the it like normal provider:@Component ({ 'todos', providers: [Todoservice, Loggerprovider], Template: ' ... ' })It w

While you had multiple streams flowing into your scan operator, you'll need to map each stream to the specific values you Need to update your state the This is the want. This lesson covers using the "map operator to determine" What the "click" and "Interval should do" is updated.Import {Component} from 'Angular2/core'; import {bootstrap} from 'Angular2/platform/browser'; import {Observable} from 'rxjs/observable'; Import'Rxjs/add/observable/interval'; Import'Rxjs/add/observable/merge'; Import'Rx

Angular Learning (2): Controller definition summary, angularcontroller The above section summarizes the ng-view application, and separates the O M background into two interfaces for logical Controller processing. This article will summarize the knowledge used by the Controller in the project: $ Scope: scope object, which only represents the current Controller object. All objects in this scope are declared

1. Introduction of ANGULAR2 predefined types　　Import {Component,View,Bootstrap} from "Angular2/angular2" ;2. Implement a ANGULAR2 component　　@Component({selector:"Ez-app"})//location rendered to using the CSS selector via the Selector property 　　@View({template:' } ')//view, specify the rendered template through the Templates property 　　Class Ezapp{} 3. Rendering components to the DOMbootstrap(ezapp); The above equivalent,Class Ezapp {}Ezapp.an

Async Pipe:The asynce pipe receive a Promise or Observable as input and subscribes to the input, evetually emitting the value (s) Cha Nges arrive.In the demo, the logic was fom the list component, we ask service to get Heros by calling Start War APIs, on the service SID E, we only return an array of heros with Observalbe type: Getheros () { returnthis. _http. Get('http://swapi.co/api/people') Res.json (). Results) . Catch (this. handleError); class hero{

Http://www.alliedjeep.com/2547.htmAngularJS Code (users.js)var Users = angular.module (' Users ', []);Users.controller (' userlist ', function ($scope, $http) {$scope. start = 0;$scope. showlimit = 10;$scope. Count = 0;/* Default Users List */$http. Get (' welcome/get_users ' + '/' + $scope. Start + '/' + $scope. Showlimit). Success (function (data) {$scope. Users = data;});/* Count Users */$http. Get (' Welcome/count_users '). Success (function (data) {$scope. Count = data;});/* Pagination */$s

Showing How to set up a Pipe, takes multiple updating inputs for multiple Component sources.Import {Component, View, Ngfor, form_directives} from ' Angular2/angular2 '; import {Todoservice} from'./todoservice '; import {Todoitemrender} from'./todoitemrender '; import {StartsWith} from'./startswith '; import {Simplesearch} from'./simplesearch '; import {letterselect} from'./letterselect '; import {Todosearch} from'./todosearch '; @Component ({selector:' Todo-list '}) @View ({pipes: [StartsWith, S

Besides @Input (), we can also use properties on the @Component, to pass the data.Import {Component, View, Ngfor, Input} from ' Angular2/angular2 '; @Component ({selector:' Reddit-article '}) @View ({directives: [], Template: ' `}) Export class Redditarticle {@Input () article:article; Voteup () { This. Article.voteup (); return false; } votedown () { This. Article.votedown (); return false; }}Works the same as:Import {Component, View, Ngfor, Input} from ' Angular2/angular2 '; @Component (

write providers for other types of storage areas. The provider is the main integration point of the Sync Framework. Shows the Sync Framework's advanced architecture. Synchronization always happens between two copies (or "nodes") shown in the figure, but the synchronization community (or "Topology") can be in any shape, such as a central radiation, a pair, and so on. Except for some exceptions, each participant can synchronize on a
