  • [Angular 2] Template property syntax

    This lesson covers using the [input] syntax to change an element property such as “hidden” or “content-editable”. Using properties eliminates the need for Angular 1’s old directives such as ng-show and ng-hide as you’re now able to directly access any property on your element.

     todoService.ts
    export class TodoModel{
        status: string = "started";
        constructor(
            public title: string = ""
        ){}
    
        toggle(): void{
            if(this.status === "started") this.status = "completed";
            else this.status = "started";
        }
    }

    todoList.ts

    import {Component, View, NgFor} from 'angular2/angular2';
    import {TodoService} from './todoService';
    
    @Component({
        selector: 'todo-list'
    })
    @View({
        directives: [NgFor],
        template: `
              <div>
                  <div *ng-for="#todo of todoService.todos">
                      <span [content-editable]="todo.status === 'started'">{{todo.title}}</span>
                      <button (click)="todo.toggle()">Toggle</button>
                  </div>
              </div>
        `
    })
    
    export class TodoList{
        constructor(
            public todoService:TodoService
        ){
    
        }
    }
