Ionic Components

Ionic组件

Navigation

导航

typescript
import { NavController } from '@ionic/angular';

constructor(private navCtrl: NavController) {}

navigateForward() {
  this.navCtrl.navigateForward('/details');
}

navigateBack() {
  this.navCtrl.back();
}
typescript
import { NavController } from '@ionic/angular';

constructor(private navCtrl: NavController) {}

navigateForward() {
  this.navCtrl.navigateForward('/details');
}

navigateBack() {
  this.navCtrl.back();
}

UI Components

UI组件

  • Use 
    ion-header
    , 
    ion-content
    , 
    ion-footer
    for page structure
  • Leverage 
    ion-list
    , 
    ion-item
    for lists
  • Use 
    ion-button
    , 
    ion-fab
    for actions
  • Apply 
    ion-modal
    , 
    ion-popover
    for overlays
  • 使用
    ion-header
    、
    ion-content
    、
    ion-footer
    构建页面结构
  • 利用
    ion-list
    、
    ion-item
    创建列表
  • 使用
    ion-button
    、
    ion-fab
    实现操作按钮
  • 应用
    ion-modal
    、
    ion-popover
    实现浮层效果

Styling

样式

  • Use SCSS for component-specific styles
  • Leverage Ionic CSS variables for theming
  • Apply platform-specific styling when needed
  • Use responsive utilities for different screen sizes
scss
:host {
  --ion-background-color: var(--ion-color-light);
}

.custom-card {
  --background: var(--ion-color-primary-tint);
}
  • 使用SCSS编写组件专属样式
  • 利用Ionic CSS变量实现主题定制
  • 必要时应用平台专属样式
  • 使用响应式工具适配不同屏幕尺寸
scss
:host {
  --ion-background-color: var(--ion-color-light);
}

.custom-card {
  --background: var(--ion-color-primary-tint);
}
