this.formGroup = this.formBuilder.group({
images: this.fb.array([])
});
I add new element in this way:
this.images.push(new FormControl(new ImageCreateForm(this.imageResponse.id)));
get images(): FormArray {
return <FormArray>this.formGroup.controls.images;
}
My classes:
export class ImageCreateForm {
id: number;
constructor(id: number) {
this.id = id;
}
}
export class ImageResponse {
id: number;
url: string;
}
When I added images, then my {{ formGroup.value | json }}
is:
"images": [
{
"id": 501
},
{
"id": 502
},
{
"id": 503
}
]
I want to remove images (for example only image with id=502
) from formGroup
before when I send my form POST request. Is it possible?
I tried use reset
method, but this remove all elements:
this.images.reset({"id":image.id});
. Where image
it is a ImageResponse
object.
Result: {"images": [ null, null, null ]}
, but I want:
"images": [
{
"id": 501
},
{
"id": 503
}
]
