如何从 Ionic 2 中的后退按钮更改标签?

问题描述

附上代码:

<ion-navbar *navbar>
</ion-navbar>

后退按钮已启用.但我需要自定义它(图标或标签).是否可以?在 docs/api 中找不到任何内容.

the back button is enabled. But I need to customize it (the icon or the label). Is it possible? Can't find anything in the docs/api.

推荐答案

您可以在您的 app.html 中设置返回按钮文本，如 ionic 链接 http://ionicframework.com/docs/v2/api/config/Config

you can set back button text in your app.html as mentioned in the ionic link http://ionicframework.com/docs/v2/api/config/Config

@App({
  template: `<ion-nav [root]="root"></ion-nav>`
  config: {
    backButtonText: 'Go Back',
    iconMode: 'ios',
    modalEnter: 'modal-slide-in',
    modalLeave: 'modal-slide-out',
    tabbarPlacement: 'bottom',
    pageTransition: 'ios',
  }
})

ionic 2 beta 8 中的更新

import {ionicBootstrap} from 'ionic-angular';

ionicBootstrap(AppRoot, customProviders, {
  backButtonText: 'Go Back',
  iconMode: 'ios',
  modalEnter: 'modal-slide-in',
  modalLeave: 'modal-slide-out',
  tabbarPlacement: 'bottom',
  pageTransition: 'ios',
});

ionic 2 rc.0 及更高版本以及 ionic 3 中的更新

在 ionic 2 rc.0 及更高版本中，我们需要在导入数组下的 app.module.ts 中包含配置.

In ionic 2 rc.0 and up, we need to include the configs in app.module.ts under imports array.

@NgModule({   
 declarations: [
    MyApp,
    Home   
 ],   
 imports: [
    IonicModule.forRoot(MyApp, {
      tabsPlacement: 'top',
      backButtonText: 'Back'
     })],
 bootstrap: [IonicApp],
 entryComponents: [
    MyApp,
    Home   ],
 providers: [MyService]
})
