js代码调用webdrvier怎么处理NoSuchWindowError异常需要先require

('webdriver')，然后使用try-catch语句捕获NoSuchWindowError异常，然后在catch语句中重新启动WebDriver实例。以下是示例代码：

const webdriver = require('webdriver');

let driver = new webdriver.Builder().forBrowser('chrome').build();

try {
  // do something with driver
} catch (err) {
  if (err.name === 'NoSuchWindowError') {
    driver.quit();
    driver = new webdriver.Builder().forBrowser('chrome').build();
    // retry the failed code with the new driver instance
  }
}
