Question

我已经获得了一个工作链接而没有尝试访问它的参数：

//home.ts
import { Component } from '@angular/core';

import { NavController } from 'ionic-angular';

import {FishPage} from '../fish';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
  providers: [FishPage]
})
export class HomePage {
  constructor(public navCtrl: NavController, private goFish: FishPage,) {
       this.goFish = FishPage;
  }

  playPoker(){
    this.navCtrl.push(FishPage, {
        drag: 'ichabod'
    });
  }

}

该链接有效，直到我将代码添加到FishPage以访问传入的信息。这是FishPage：

import { Component } from '@angular/core';
import { NavController, NavParams } from 'ionic-angular';

@Component({
  templateUrl: 'fish.html'
})
export class FishPage {
  constructor(public navCtrl: NavController, public navParams: NavParams) {
    let param = this.navParams.get('drag');
  }
}

由于某种原因，代码返回此错误：

[14:18:36]错误：src / pages / home / home.ts（16,4）：错误TS2322：类型 'typeof FishPage'不能分配给'FishPage'类型。属性 'typeof FishPage'
类型中缺少'navCtrl'

离子2导航不适用于争论
