Ionic2 渐变隐藏导航栏|标题栏

废话少说 直接上代码....

//导入需要用到的命名空间 ViewChild,Content
import { Component, ViewChild } from '@angular/core';
import { NavController, ModalController, ToastController, Content } from 'ionic-angular';

@Component({
  selector: 'home',
  templateUrl: 'home.html',
})
export class HomePage {
  @ViewChild(Content) content: Content;  //获取界面Content的实例对象

 //获取滑动的TOP值,并在200px时使标题栏达到透明 onPageScroll(event) { let position = event.target.scrollTop;//取滑动TOP值 this.transrate = 2 - position / 100; document.getElementById("home_title").style.opacity = this.transrate.toString();   // this.content.resize(); console.log(position); }
 //界面初始化时注册界面滑动事件 ngAfterViewInit() { this.content.addScrollListener(this.onPageScroll); } }




//界面代码
给标题栏加个ID即可
<ion-header style="opacity:0" id="home_title">
