Angular Material - 进度条



md-progress-circularmd-progress-linear 是 Angular 的进度指示器指令,用于在应用程序中显示加载内容消息。

属性 - md-progress-circular

下表列出了md-progress-circular的不同属性的参数和描述。

序号 参数和描述
1

* md-mode

从两种模式中选择一种:'determinate'(确定性)和 'indeterminate'(不确定性)。如果 md-mode 值设置为未定义或指定为非这两种有效模式之一,则 .ng-hide 将自动作为样式应用于组件;如果未配置,则 md-mode = "indeterminate" 将自动注入为属性。但是,如果也指定了 value = "",则 md-mode = "determinate" 将自动注入。

2

value

在确定性模式下,此数字表示圆形进度的百分比。默认值为 0。

3

md-diameter

这指定了圆形进度的直径。该值可以是百分比(例如“25%”)或像素大小值(例如“48”)。如果此属性不存在,则假定默认值为“48px”。

示例

以下示例显示了md-progress-circular指令的使用以及圆形进度条的使用。
