如题：页面需要保持屏幕常亮，有相关的api和示例吗？

Answer 1

请参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-apis-window-0000001820880785\#ZH-CN\_TOPIC\_0000001820880785\_\_setwindowkeepscreenon9

设置屏幕常亮，不熄屏。

获取窗口实例对象后，调用setWindowKeepScreenOn方法可设置屏幕是否常亮。

import { BusinessError } from '@ohos.base';
import window from '@ohos.window';
let isKeepScreenOn: boolean = true;
let windowClass: window.Window = window.findWindow("test");
try {
windowClass.setWindowKeepScreenOn(isKeepScreenOn， (err: BusinessError) => {
const errCode: number = err.code;
if (errCode) {
console.error('Failed to set the screen to be always on. Cause: ' + JSON.stringify(err));
return;
}
console.info('Succeeded in setting the screen to be always on.');
});
} catch (exception) {
console.error('Failed to set the screen to be always on. Cause: ' + JSON.stringify(exception));
}
