线程“主” org.openqa.selenium.WebDriverException中的异常：未知错误：未定义参数

Question

我想通过JavaScript Executor在Selenium Webdriver中选择日期。

    webDriver.get("https://www.spicejet.com/");
    WebElement date = webDriver.findElement(By.id("ctl00_mainContent_view_date1"));
    String dateVal = "20-10";
    selectDateByJS(webDriver, date, dateVal);
}

public static void selectDateByJS(WebDriver webDriver, WebElement element, String dateVal) {
    JavascriptExecutor js = ((JavascriptExecutor) webDriver);
    js.executeScript("argument[0].setAttribute('value','" + dateVal + "');", element);
}
