md-slider是一个Angular指令，用于显示范围组件。 它有两种模式 -
normal - 用户可以在宽范围的值之间滑动。 默认情况下存在此模式。
discrete - 用户可以在所选值之间滑动。 要启用离散模式，请使用mddiscrete和step属性。
属性 (Attributes)
下表列出了md-slider的不同属性的参数和说明。
| Sr.No | 参数和描述 |
|---|---|
| 1 | md-discrete 这决定了是否启用离散模式。 |
| 2 | step 允许用户选择的值之间的距离。 默认情况下，它为1。 |
| 3 | min 允许用户选择的最小值。 默认情况下，它为0。 |
| 4 | max 允许用户选择的最大值。 默认情况下，它是100。 |
例子 (Example)
以下示例显示了md-sidenav的使用以及sidenav组件的用法。
