Question

我已经浏览了ng2-smart表，我已经创建了文档中提到的用于实现列单元格功能的列我已经按照以下链接 https://github.com/akveo/ng2-smart-table/blob/master/src/app/pages/examples/custom-edit-view/basic-example-button-view.component.ts

但我无法捕捉其他组件中ButtonViewComponent中提到的事件。

import { Component, OnInit, Input, Output, EventEmitter } from '@angular/core';
import { ViewCell } from 'ng2-smart-table';
import {Routes, RouterModule, Router} from '@angular/router';
import {Observable} from "rxjs";
@Component({
    selector: 'button-view',
    template: `
    <a (click)="onClick()">{{ renderValue }}</a>
  `,
})
export class ButtonViewComponent implements ViewCell, OnInit {
    renderValue: string;

    @Input() value: string | number = '';
    @Input() rowData: any='Hello';

    @Output() save: EventEmitter<any> = new EventEmitter();
    @Output() sendInformationTOANI: EventEmitter<any> = new EventEmitter();

    ngOnInit() {
        this.renderValue = this.value.toString().toUpperCase();
    }
    constructor(private router: Router){

    }
    onClick() {
        this.save.emit(this.rowData);
        console.log('emit data');
// Here i want to catch this event in other component!!
    }


}

@注意：我尝试过使用@Input和@Output，但仍然无法捕获事件在此先感谢!!

假设您已在Parent Component中声明了列，则可以使用 onComponentInitFunction（）函数访问子组件的事件。例如

{
  title: "Actions",
  type: "custom",
  renderComponent: ButtonViewComponent,
  onComponentInitFunction :(instance) => {
    instance.save.subscribe(row => {
     //now you can access value from child component here
  });
 }
};
