I am trying to get the result return by the subscriber function to another function. But when I console it there is only an empty array
I tried including it the ngOnInit function of the component but that also failed.
ngOnInit() {
var id="5d943564ca97f725c8e6b8fa";
this.cartService.getCartById(id).subscribe(res => {
console.log(res['product']);
this.cartItems=res['product'];
console.log(this.cartItems+"cartItems");
this.cartService.changeCartItems(res['product']) ;
}, err => {
console.log(err);
});
But i get
Array [ {…} ]
[object Object]cartItems
[object Object]changeCartItem
If you concatenate anything with string (cartItems
in your case) - that "anything" will be converted to string
So, either remove concatenation in console.log call or do
console.log(JSON.stringify(this.cartItems) + "cartItems");
