我想在angular2项目中使用角度材料
autocomplete组件.我在模板中添加了以下内容.
<md-input-container>
<input mdInput placeholder="Category" [mdAutocomplete]="auto" [formControl]="stateCtrl">
</md-input-container>
<md-autocomplete #auto="mdAutocomplete">
<md-option *ngFor="let state of filteredStates | async" [value]="state">
{{ state }}
</md-option>
</md-autocomplete>
以下是我的组件.
import {Component,OnInit} from "@angular/core";
import {ActivatedRoute,Router} from "@angular/router";
import {FormControl} from "@angular/forms";
@Component({
templateUrl: './edit_item.component.html',styleUrls: ['./edit_item.component.scss']
})
export class EditItemComponent implements OnInit {
stateCtrl: FormControl;
states = [....some data....];
constructor(private route: ActivatedRoute,private router: Router) {
this.stateCtrl = new FormControl();
this.filteredStates = this.stateCtrl.valueChanges.startWith(null).map(name => this.filterStates(name));
}
ngOnInit(): void {
}
filterStates(val: string) {
return val ? this.states.filter((s) => new RegExp(val,'gi').test(s)) : this.states;
}
}
我收到以下错误.看起来没有找到formControl指令.
Can’t bind to ‘formControl’ since it isn’t a known property of ‘input’
这是什么问题？
使用formControl时,必须将ReactiveFormsModule导入导入数组.
例：
import {FormsModule,ReactiveFormsModule} from '@angular/forms';
@NgModule({
imports: [
BrowserModule,FormsModule,ReactiveFormsModule,MaterialModule,],...
})
export class AppModule {}
