无admob的interstitial close event ionic3

Question

使用Admob-free plugin。

如何触发间隙关闭事件，

//this is the code found for javscript
document.addEventListener('admob.interstitial.events.CLOSE', function (event) {
    console.log(event)
    admob.interstitial.prepare()
})
//i want this code  in ionic3 

有人可以帮助如何在typescript/ ionic3中做到这一点吗？

document.addEventListener在typescript中显示错误

Answer 1

import {Component, Renderer} from '@angular/core';    
constructor(renderer: Renderer) {

            renderer.listenGlobal('document', 'admob.interstitial.events.CLOSE', (event) => {
                console.log(event);
            });

        }

你可以这样做

最好的方法就是像下面这样，但是不要忘记在构造函数中注册AdmobFree

constructor(
    private admobFree: AdMobFree,
    public platform: Platform
) {

    // Handle interstitial's close event
    this.admobFree.on('admob.interstitial.events.CLOSE').subscribe(() => {
       // handle interstitial close
    });
}
