可访问性

(WAI-ARIA: https://www.w3.org/TR/wai-aria-practices/#slider)

The component handles most of the work necessary to make it accessible. However, you need to make sure that:

  • Each thumb has a user-friendly label (aria-label, aria-labelledby or getAriaLabel prop).
  • Each thumb has a user-friendly text for its current value. 除非数值的含义显而易见。 你可以通过getAriaValueText 或者 aria-valuetext 更改提示气泡的名称。
