-* `componentInstance`: An instance of the [`Component`](/reference/react/Component) subclass. For example, `this` inside a class component.

-#### Returns {/*returns*/}
+#### 返回值 {/*returns*/}
 
-`findDOMNode` returns the first closest browser DOM node within the given `componentInstance`. When a component renders to `null`, or renders `false`, `findDOMNode` returns `null`. When a component renders to a string, `findDOMNode` returns a text DOM node containing that value.
+`findDOMNode` 方法返回与给定的 `componentInstance` 中最接近的浏览器 DOM 节点。当组件渲染为 `null` 或 `false` 时，`findDOMNode` 返回 `null`。当组件渲染为字符串时，`findDOMNode` 返回一个包含该值的文本 DOM 节点。
 
-#### Caveats {/*caveats*/}
+#### 注意 {/*caveats*/}
 
-* A component may return an array or a [Fragment](/reference/react/Fragment) with multiple children. In that case `findDOMNode`, will return the DOM node corresponding to the first non-empty child.
+* 组件可能会返回包含多个子元素的数组或 [Fragment](/reference/react/Fragment)。在这种情况下，`findDOMNode` 会返回第一个非空子节点对应的 DOM 节点。
 
-* `findDOMNode` only works on mounted components (that is, components that have been placed in the DOM). If you try to call this on a component that has not been mounted yet (like calling `findDOMNode()` in `render()` on a component that has yet to be created), an exception will be thrown.
+* `findDOMNode` 只对已经挂载到 DOM 上的组件有效。如果你尝试在一个还未挂载的组件上调用 `findDOMNode()`（比如在一个还未创建的组件的 `render()` 方法中调用 `findDOMNode()`），会抛出异常。
 
-* `findDOMNode` only returns the result at the time of your call. If a child component renders a different node later, there is no way for you to be notified of this change.
+* `findDOMNode` 只会返回调用时的结果，你无法得知组件是否在之后渲染了不同的节点。
 
-* `findDOMNode` accepts a class component instance, so it can't be used with function components.
+* `findDOMNode` 接受类组件实例作为参数，而不能用于函数式组件。

-Notice that calling `findDOMNode(this)` inside `AutoselectingInput` still gives you the DOM `<input>`--even though the JSX for this `<input>` is hidden inside the `MyInput` component. This seems convenient for the above example, but it leads to fragile code. Imagine that you wanted to edit `MyInput` later and add a wrapper `<div>` around it. This would break the code of `AutoselectingInput` (which expects to find an `<input>`).
+请注意，即使 `<input>` 被隐藏在 `MyInput` 组件中，在 `AutoselectingInput` 中调用 `findDOMNode(this)` 仍然会返回 `<input>`。这在上面的例子中似乎很方便，但它会导致代码变得非常脆弱。想象一下，如果你以后想编辑 `MyInput` 并使用 `<div>` 包装，但是这将会破坏 `AutoselectingInput` 的代码（因为它期望找到 `<input>`）。
