+
+获取浏览器操作的徽章文本颜色。
+
+> [!NOTE]
+> 该 API 在 Manifest V3 或更高版本中可用。
+
+在 Firefox 中，除非使用 {{WebExtAPIRef("action.setBadgeTextColor()")}} 明确设置了徽章文本颜色，否则徽章文本颜色会自动设置为黑色或白色，以最大程度与指定的徽章背景颜色形成对比。例如，如果将徽章背景颜色设置为白色，则默认的徽章文本颜色将设置为黑色，反之亦然。
+
+其他的浏览器总是使用白色作为文本颜色。
+
+这是一个返回 [`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise) 的异步函数。
+
+## 语法
+
+```js-nolint
+browser.action.getBadgeTextColor(
+  details // 对象
+)
+```
+
+### 参数
+
+- `details`
+
+  - : `object`。
+
+    - `tabId` {{optional_inline}}
+      - : `integer`，指定要获取徽标文本颜色的标签页。
+    - `windowId` {{optional_inline}}
+      - : `integer`，指定要获取徽标文本颜色的窗口。
+
+<!---->
+
+- 若同时指定了 `windowId` 和 `tabId`，则函数出错。
+- 若同时未指定 `windowId` 和 `tabId`，则返回全局徽标的文本颜色。
+
+### 返回值
+
+以 {{WebExtAPIRef('action.ColorArray')}} 形式兑现获取到的颜色的 [`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise)。
+
+## 示例
+
+输出徽标的文本颜色：
+
+```js
+function onGot(color) {
+  console.log(color);
+}
+
+function onFailure(error) {
+  console.log(error);
+}
+
+browser.action.getBadgeTextColor({}).then(onGot, onFailure);
+```

+> [!NOTE]
+> 该 API 基于 Chromium 的 [`chrome.action`](https://developer.chrome.com/docs/extensions/reference/action/#method-getBadgeTextColor) API。该文档衍生于 Chromium 代码中的 [`browser_action.json`](https://chromium.googlesource.com/chromium/src/+/master/chrome/common/extensions/api/browser_action.json)。
