[英]Can't bind data from web api to select option in Angular
我试图将一些数据绑定到 Angular 6 中的一个选择选项,我为此使用了 *NgFor:Json 数据结构如下:
{
"addresses":[
{
"address":"xxxxxxx",
"address_line1":"None",
"address_line2":"None",
"address_line3":"",
"billing":false,
"id":79,
"name":"xxxxx",
"phone_number":null,
"postal_code":"xxxxx",
"town":"xxxxx"
},
]
}
因此,要将其绑定到我正在执行的选择选项中:
<option value="null" disabled="true" [selected]="true">Select your option</option>
<option *ngFor="let item of address" [value]="item">
{{item.address}}
</option>
获取数据的ts文件:
customerAddress = [];
private getCustomerAddress() {
this.service.getCustomerAddress(this.customer_id).subscribe((data) => {
console.log('Result - ', data);
console.log('Customer address data is received');
this.customerAddress = data;
})
}
与此相关的服务:
getCustomerAddress(customerId): Observable<any> {
return this.http.get<any>(this.customerAddressApiUrl + "/" + customerId)
.pipe(
catchError(this.handleError)
);
}
选择选项中没有显示数据? 但是console.log 中的数据很好。
这是正确的做法:
<option *ngFor="let item of customerAddress.addresses" [value]="item">
{{item.address}}
</option>
您正在浏览的数组的名称是customerAddress
而不是adresses
