HarmonyOS window.findWindow("test")问题

这个test是窗口名字，即Configuration中的name是自行定义的，参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-window-V5#windowfindwindow9

示例参考：

import { window } from '@kit.ArkUI';
import { BusinessError } from '@kit.BasicServicesKit';

let windowClass: window.Window | null = null;
// 方式一：创建子窗口。
let config: window.Configuration = { name: "subWindow", windowType: window.WindowType.TYPE_APP };
window.createWindow(config, (err: BusinessError, data) => {
  let errCode: number = err.code;
  if (errCode) {
    console.error('Failed to create the subWindow. Cause: ' + JSON.stringify(err));
    return;
  }
  console.info('Succeeded in creating subWindow. Data: ' + JSON.stringify(data));
  windowClass = data;
});
// 方式二：查找得到子窗口。
try {
  windowClass = window.findWindow('subWindow');
} catch (exception) {
  console.error('Failed to find the Window. Cause: ' + JSON.stringify(exception));
}
