【问题描述】:
当我们点击父按钮时,我们希望使用父级的子响应式表单数据。目前我们正在使用 viewchild 来获取子组件引用。我们正在获取所有静态数据,但不是表单填充数据...................................................... ..................................................... ......
parent.component.ts
@ViewChild(DetailsComponent) childrenComponent: childrenComponent;
save(){
let model=this.childrenComponent.buildDetailsModel();
/*here api to save model*/
}
children.component.ts
buildDetailsModel(): Details {
var a = {
reportedToId: this.detailsForm.get('reportedTo').value,
reportedOn: this.detailsForm.get('reportedTime').value,
identifiedById: this.detailsForm.get('identifiedBy').value,
identifiedOn: this.detailsForm.get('dateAndTimeIdentified').value,
locationTypeId: this.detailsForm.get('locationType').value,
addressId: this.detailsForm.get('locationAddress').value,
AddressLine: this.detailsForm.get('locationOfAddress').value,
description: this.detailsForm.get('description').value,
PeopleExposed: this.dataSource
};
return a;
}
parent.html
<child></child>
child.html
