ion-progress-bar
进度条告知用户正在进行的进程的状态，例如加载应用、提交表单或保存更新。进度条有两种类型：determinate 和 indeterminate。
¥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.
确定性
¥Determinate
确定是默认类型。当操作的百分比已知时应使用它。进度通过设置 value 属性来表示。这可用于显示轨道从 0% 增加到 100% 的进度。
¥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.
缓冲
¥Buffer
如果设置了 buffer 属性，缓冲流将显示动画圆圈以指示活动。buffer 属性的值也将由有多少可见轨道来表示。如果 buffer 的值小于 value 属性，则不会有可见轨道。如果 buffer 等于 1 则缓冲流将被隐藏。
¥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.
不确定性
¥Indeterminate
当未知过程需要多长时间时，应使用不确定类型。进度条并不与 value 绑定，而是沿着轨道不断滑动，直到过程完成。
¥The indeterminate type should be used when it is unknown how long the process will take. The progress bar is not tied to the value, instead it continually slides along the track until the process is complete.
