我有一个名为“data”的变量,其中包含以下数据:
{
id: 1,
date: "2018-03-13T16:18:03",
date_gmt: "2018-03-13T16:18:03",
guid: {},
modified: "2018-05-03T17:25:36",
modified_gmt: "2018-05-03T17:25:36",
slug: "hello-world",
status: "publish",
type: "post",
title: {
rendered: "Hello world!"
},
...等
在我的app.component.html上,当我使用时,ID显示正常:
[ngModel]="data?.id"
当我尝试显示标题时出现问题。
当我尝试:
[ngModel]="data?.title.rendered"
我得到:[object Object]
但是当我使用时:
value="{{data?.title.rendered}}"
显示标题。
我怎样才能获得
[ngModel]="data?.title.rendered"
显示标题而不是[object Object]
?
答案 0 :(得分:2)
我做了这个stackblitz,
组件中的:
export class AppComponent {
data = {
id: 1,
date: "2018-03-13T16:18:03",
date_gmt: "2018-03-13T16:18:03",
guid: {},
modified: "2018-05-03T17:25:36",
modified_gmt: "2018-05-03T17:25:36",
slug: "hello-world",
status: "publish",
type: "post",
title: {
rendered: "Hello world!"
}
}
myForm:FormGroup;
constructor(private formBuilder: FormBuilder) {
this.myForm = this.formBuilder.group({
"title": ['', Validators.required]
});
}
}
in html:
<form [formGroup]="myForm" >
<input type="text" class="form-control m-input" formControlName="title" name="title" id="title-field" placeholder="Title" [(ngModel)]="data?.title.rendered">
</form>
