md-button是Angular Directive，是一个带有可选墨水波纹的按钮指令（默认情况下启用）。 如果提供了href或ng-href属性，则此指令充当锚元素。
属性 (Attributes)
下表列出了md-button不同属性的参数和说明。
| Sr.No | 参数和描述 |
|---|---|
| 1 | md-no-ink 如果设置为true，则禁用波纹墨水效果。 |
| 2 | ng-disabled 根据表达式启用/禁用。 |
| 3 | md-ripple-size 覆盖默认的纹波大小逻辑。 选项:完整，部分，自动。 |
| 4 | aria-label 为可访问性按钮添加替代文本，对图标按钮很有用。 如果未找到默认文本，则会记录警告。 |
例子 (Example)
以下示例显示了md-button指令的使用以及各种类型的按钮。
