| 我们知道 [props 是只读的](/docs/components-and-props.html#props-are-read-only)。当 `temperature` 存在于 `TemperatureInput` 组件的 state 中时，组件只能通过调用 `this.setState()` 去修改它。然而现在，`temperature` 是由父组件传入的 prop，`TemperatureInput` 组件便失去了对它的控制权。 | ||

| In React, this is usually solved by making a component "controlled". Just like the DOM `<input>` accepts both a `value` and an `onChange` prop, so can the custom `TemperatureInput` accept both `temperature` and `onTemperatureChange` props from its parent `Calculator`. | ||
| 在 React 中，这个问题通常是通过让组件“受控”来解决的。与 DOM 中的 `<input>` 接受 `value` 和 `onChange` 一样，自定义的 `TemperatureInput` 组件接受 `temperature` 和 `onTemperatureChange` 这两个来自父组件 `Calculator` 的 props。 |
