Framework7 - 进度条
描述
进度条可用于向用户显示资产的加载或任务的进度。您可以使用progressbar类指定进度条。当用户不知道请求的加载过程需要多长时间时，可以使用progressbar-infinite类。
进度条 JavaScript API
进度条可以与 JavaScript API 一起使用，通过以下方法指定show、hide和Progress属性 -
| 序列号 | 方法 | 描述及参数 |
|---|---|---|
| 1 | myApp.setProgressbar（容器、进度、速度） | 它设置任务进度的进度条。
|
| 2 | myApp.hideProgressbar（容器） | 它隐藏了进度条。
|
| 3 | myApp.showProgressbar（容器、进度、颜色） | 它显示进度条。
|
例子
以下示例显示动画确定和不确定进度条以指示 Framework7 中的活动 -

输出
让我们执行以下步骤来看看上面给出的代码是如何工作的 -
将上面给定的 HTML 代码保存为服务器根文件夹中的Progress_bar.html文件。
以 http://localhost/progress_bar.html 打开此 HTML 文件，输出显示如下。
该示例显示进度条，指示操作完成该过程所需的时间，并显示不同类型的进度条来指示活动。
