Question

import { Component } from '@angular/core';

import { GridOptions, RowNode } from 'ag-grid/main';
import { ICellRendererAngularComp } from 'ag-grid-angular';


@Component({
    selector: 'qrp-drop-down-selector',
    template: `
    <input type="checkbox" [checked]="params.value" style="margin-top: -6px;" (change)="params.setValue($event.target.checked ? true : null)">
    `
})
export class QrpDropdownEditorComponent implements ICellRendererAngularComp {
    private params: any;

    agInit(params: any): void {
        this.params = params;
    }
}

我创造了这种组件。但是当我把复选框错误 self.context.params.setValue不是一个函数我到底错了什么？

Angular正在使用setValue（）方法查找对象。它找不到它。尝试这样的事情：

@Component({
    selector: 'qrp-drop-down-selector',
    template: `
    <input type="checkbox" [checked]="params.value" style="margin-top: -6px;" (change)="setValue($event.target.checked ? true : null)">
    `
})
export class QrpDropdownEditorComponent implements ICellRendererAngularComp {
    private params: any;

    agInit(params: any): void {
        this.params = params;
    }

    setValue(val: boolean) {
       this.params = val;
    }
}

Angular 2复选框params.setValue不是函数错误？
