我有这样的数组:
dataTest = [{name: 'Foo'},{name: 'Bar'}]
我正在显示matIntput中的所有数据。单击时,我将在数组中添加新行并显示空输入。没关系,但是当我将数据更改为新行而将null更改为类似于John之类的内容,然后单击“保存”时,数组中没有任何更改,看起来像这样:
dataTest = [{name: 'Foo'},{name: 'Bar'},{name: null}]
这是我的app.compoent.html:
<mat-dialog-content>
<div class="flex wrap vertical-align" *ngFor="let profile of dataTest; let i = index">
<mat-form-field class="profile-name name">
<input matInput placeholder="Name" value="{{profile.name}}">
</mat-form-field>
<div class="action-group">
<span class="add-button"(click)="add()">ADD</span>
</div>
</div>
</mat-dialog-content>
<mat-dialog-actions align="end">
<button class="background-white" mat-button mat-dialog-close>CANCEL</button>
<button class="background-primary" mat-button [mat-dialog-close]="true" cdkFocusInitial (click)="save(dataTest)">SAVE</button>
</mat-dialog-actions>
这是我的app.compoent.ts:
private add(): void {
const rules: any = {
name: ''
};
this.dataTest.push(rules);
console.log(this.dataTest);
};
private save(dataTest) {
console.log(dataTest)
}
任何帮助或想法,我做错了!

使用ngModel如下:-
{
"error": {
"message": "Callback must be a function"
}
}
如果尚未导入FormsModule,请不要忘记导入它。
