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

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{

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 (

Select the C ++ language instead of the C preprocessing, but you need to use the pre-processor to understand the debugging code; 2. Declare all shared external symbols in t

Second-close-up observation (2) Using evaluate/modify (for evaluation/modification) The last way to display the value of a variable or code block is the evaluate/modify (Evaluate/Modify) window. This window can be opened like a patrol, and the evaluate/modify (Evaluate/Modify) window will pop up when you right-click on the line of code you want to evaluate/modify (evaluate/modify) and select "Debug|evaluate/modify". This window is used to evaluate a
