Angular Material - 进度条小部件
md-progress-circular 和 md-progress-linear 是 Angular 进度指令,用于显示应用程序中的加载内容消息。
属性 - md-progress-circular
下表列出了md-progress-circular不同属性的参数和说明。
Sr.No | 参数和描述 |
---|---|
1 | * md-mode 选择以下两种模式之一:"确定"和"不确定"。 如果 md-mode 值设置为 undefined(未定义)或指定为不是两 (2) 个有效模式中的 1 个,则 .ng-hide 将作为样式自动应用到组件; 如果未配置, md-mode = "infiniteate" 将作为属性自动注入。 但是,如果还指定了 value = "",则将自动注入 md-mode = "definate"。 |
2 | value 在确定模式下,该数字表示循环进度的百分比。 默认情况下,该值为 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
以下示例展示了 md-progress-circular 指令的使用以及圆形进度条的使用。

2 | md-buffer-value 在确定模式下,该数字表示主进度条的百分比。 默认情况下,该值为 0。 |
3 | md-diameter 在 buffer 缓冲模式下,这个数字代表辅助进度条的百分比。 默认情况下,该值为 0。 |
