Contents

Progress bars inform users about the status of ongoing processes, such as loading an app, submitting a form, or saving updates. There are two types of progress bars: determinate and indeterminate.

Progress Type

Determinate

Determinate is the default type. It should be used when the percentage of an operation is known. The progress is represented by setting the value property. This can be used to show the progress increasing from 0 to 100% of the track.

If the buffer property is set, a buffer stream will show with animated circles to indicate activity. The value of the buffer property will also be represented by how much visible track there is. If the value of buffer is less than the value property, there will be no visible track. If buffer is equal to 1 then the buffer stream will be hidden.

Indeterminate

実行中の操作を表します。操作にかかる時間を示す必要はありません。

reversed="true"を指定した場合、ロード前状態を表すための表示となります。

Usage

<!-- Default Progressbar -->
<ion-progress-bar></ion-progress-bar>

<!-- Default Progressbar with 50 percent -->
<ion-progress-bar value="0.5"></ion-progress-bar>

<!-- Colorize Progressbar -->
