ion-toolbar

Các thanh công cụ được đặt bên trên hoặc bên dưới nội dung. Khi một thanh công cụ được đặt trong một thanh công cụ, <ion-header>nó sẽ xuất hiện cố định ở đầu nội dung và khi nó ở trong một thanh công cụ, nó sẽ xuất hiện cố định ở cuối nội dung <ion-footer>. Nội dung toàn màn hình sẽ cuộn sau thanh công cụ trong đầu trang hoặc chân trang. Khi được đặt trong một <ion-content>, các thanh công cụ sẽ cuộn theo nội dung.

Buttons

Các nút được đặt trong thanh công cụ phải được đặt bên trong phần tử <ion-buttons>. Phần tử <ion-buttons> có thể được định vị bên trong thanh công cụ bằng cách sử dụng một vị trí được đặt tên. Biểu đồ dưới đây có mô tả về từng vị trí.

Collapsible Large Titles

Ionic cung cấp một cách để tạo tiêu đề có thể thu gọn tồn tại trên các ứng dụng iOS gốc. Để có được thiết lập này ion-title, bạn cần phải định cấu hình các phần tử ion-header và (tùy chọn) của bạn ion-buttons.

<template>
  <ion-header :translucent="true">
    <ion-toolbar>
      <ion-title>Settings</ion-title>
    </ion-toolbar>
  </ion-header>

  <ion-content :fullscreen="true">
    <ion-header collapse="condense">
      <ion-toolbar>
        <ion-title size="large">Settings</ion-title>
      </ion-toolbar>
      <ion-toolbar>
        <ion-searchbar></ion-searchbar>
      </ion-toolbar>
    </ion-header>

    ...

  </ion-content>
</template>

<script>
import { 
  IonContent, 
  IonHeader, 
  IonSearchbar, 
  IonTitle, 
  IonToolbar
} from '@ionic/vue';
import { defineComponent } from 'vue';

export default defineComponent({
  components: {
    IonContent, 
    IonHeader, 
    IonSearchbar, 
    IonTitle, 
    IonToolbar
  }
});
</script>

Trong ví dụ trên, lưu ý rằng có hai yếu tố ion-header. Đầu tiên ion-header đại diện cho trạng thái "thu gọn" của tiêu đề và thứ hai ion-header đại diện cho trạng thái "mở rộng" của tiêu đề . Chú ý rằng cái thứ hai ion-header phải có collapse="condense"và phải tồn tại bên trong ion-content. Ngoài ra, để có được kiểu tiêu đề lớn, ion-title cần phải có size="large".

<template>
  <ion-header :translucent="true">
    <ion-toolbar>
      <ion-buttons :collapse="true" slot="end">
        <ion-button>Click Me</ion-button>
      </ion-buttons>
      <ion-title>Settings</ion-title>
    </ion-toolbar>
  </ion-header>

  <ion-content :fullscreen="true">
    <ion-header collapse="condense">
      <ion-toolbar>
        <ion-buttons :collapse="true" slot="end">

Trong ví dụ này, hãy lưu ý rằng chúng tôi đã thêm hai tập hợp của ion-buttons cả hai với collapseset to true. Khi tiêu đề phụ thu gọn, các nút trong tiêu đề phụ sẽ ẩn và các nút trong tiêu đề chính sẽ hiển thị. Điều này hữu ích để đảm bảo rằng các nút tiêu đề của bạn luôn xuất hiện bên cạnh một phần tử ion-title.

ion-buttons các phần tử chưa được đặt collapse sẽ luôn hiển thị, bất kể trạng thái thu gọn. Khi sử dụng tiêu đề lớn và ion-buttons các phần tử bên trong ion-content, các phần tử ion-buttons phải luôn được đặt trong vị trí end.

Khi sử dụng các tiêu đề lớn có thể thu gọn, nó bắt buộc phải được đặt fullscreen thành true bật ion-content và translucent được đặt thành true chính ion-header.
