使用Angular 2,我从服务接收
JSON数据.像这样的东西：
{
"customerName": "foo","customerAddress": "123 Somewhere","products":
[
{
"productName": "bar","productNumber": 123
},{
"productName": "baz","productNumber": 456
}
]
}
在我的组件中,我订阅了服务以获取填充customerData.
private _getData() {
this._myService
.getData()
.subscribe(
customerData => this.customerData = customerData,error => this.errorMessage = error
);
}
此代码正常工作.
在JSON转储中,有两个数据“分组”,即客户数据和产品数据,后者在数组中.理想情况下,我想分别填充产品数据.像这样的东西：
.subscribe(
customerData => this.customerData = customerData,productData => this.productData = customerData.products
error => this.errorMessage = error
);
这是可能的,如果是这样,我将如何编码订阅？
解决方法
你可以写订阅
subscribe(
customerData =>
{
this.customerData = customerData;
this.productData =customerData.products;
},error => this.errorMessage = error
);
要么
subscribe(
function(customerData)
{
this.customerData = customerData;
this.productData =customerData.products;
},error => this.errorMessage = error
);
