我正在尝试在 Angular2 中进行最简单的两种方式绑定。我想在我的组件和它的模板之间共享一个变量。
我的模板是:
<textarea [(ngModel)]="currentQuery"></textarea>
我的组件是:
import { Component } from '@angular/core';
import { ViewChild } from '@angular/core';
import { OnInit } from '@angular/core';
@Component({
moduleId: module.id,
selector: 'vs-home',
templateUrl: 'home.component.html'
})
export class HomeComponent {
private currentQuery: string = '';
}
根据文档,这应该可以,但我得到:
Error: Uncaught (in promise): Error: Template parse errors:
Can't bind to 'ngModel' since it isn't a known property of 'textarea'. ("
<div class="query-bar-container">
<textarea [ERROR ->][(ngModel)]="currentQuery"></textarea>
<!-- <button type="button" class="btn btn-default" (click"): HomeComponent@2:15
