## zh-CN

属性适用于 `textarea` 节点，并且只有高度会自动变化。另外 `autoSize` 可以设定为一个对象，指定最小行数和最大行数。
> `1.5.0` 后 `autosize` 被废弃，请使用 `autoSize`。

## en-US

`autoSize` prop for a `textarea` type of `Input` makes the height to automatically adjust based on the content. An options object can be provided to `autoSize` to specify the minimum and maximum number of lines the textarea will automatically adjust.
> `autosize` is deprecated after `1.5.0`, please use `autoSize`.
