在子组件中,我有一个数据表,当我单击该行时,我将获取数据并将其保存在branchToDivision
中,我还有一个按钮,当我按下该按钮时,我可以发送{{ 1}}到父组件。
子组件
branchToDivision
父项
@Output() messageEvent: EventEmitter<BranchDto> = new EventEmitter<BranchDto>();
branchToDivision: BranchDto;
onSelect(record: BranchDto) {
this.branchToDivision = new BranchDto();
this.branchToDivision = record;
console.log(this.branchToDivision);
console.log(this.branchToDivision.brancH_CODE);
}
acceptBranch() {
this.onSelect(this.branchToDivision);
this.messageEvent.emit(this.branchToDivision);
this.branchModalDivision.hide();
}
父HTML
branch: BranchDto;
getBranch(branch: BranchDto): void{
this.branch = branch;
console.log(this.branch);
console.log(this.branch.brancH_CODE);
}
我尝试记录分支属性,但未定义,怎么了?任何想法都对我有帮助。

这是一种将信息从子组件发送到父组件的方法:
parent.component.html:
<div>
<child (getData)="getData($event)"></child>
</div>
在parent.component.ts中:
public getData(value): void {
console.log(value) // welcome to stackoverflow!
}
在child.component.ts中:
import {Output, EventEmitter} from '@angular/core';
@Output() public getUserData = new EventEmitter<string>();
this.getUserData.emit('welcome to stackoverflow!');
我希望我的帮助有效effective
