以下是翻译好的内容：
使用“Select”类与下拉菜单交互时，可以使用多种方法来打印[tag:drop-down-menu]中_option_元素的文本。此外，要与所有<option>标签交互，需要使用getOptions()方法。例如，要从[tag:facebook]登录页面https://www.facebook.com/中的“Day”、“Month”和“Year”option元素中打印文本，您需要使用WebDriverWait来等待elementToBeClickable()，并且您可以使用以下定位策略。
使用“id”属性从“Day”下拉菜单获取选项：
WebElement dayElement = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.id("day")));
Select selectDay = new Select(dayElement);
List<WebElement> dayList = selectDay.getOptions();
for (int i=0; i<dayList.size(); i++)
System.out.println(dayList.get(i).getText());
使用[tag:xpath]和[tag:java-8]的stream()和map()从“Month”下拉菜单获取选项：
Select selectMonth = new Select(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//select[@id='month']"))));
List<String> myMonths = selectMonth.getOptions().stream().map(element -> element.getText()).collect(Collectors.toList());
System.out.println(myMonths);
控制台输出：
[Month, Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sept, Oct, Nov, Dec]
使用[tag:css_selectors]和[tag:java-8]的stream()和map()一行代码从“Month”下拉菜单获取选项：
System.out.println(new Select(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("select#year")))).getOptions().stream().map(element -> element.getText()).collect(Collectors.toList()));
控制台输出：
[Year, 2020, 2019, 2018, 2017, 2016, ..., 1907, 1906, 1905]
英文:
There are multiple approaches to print the texts from the option elements of a [tag:drop-down-menu]. Ideally while interacting with a [tag:html-selct] you need to use the Select Class. Further to interact with all the <option> tags you need to use getOptions() method. As an example to print the texts from the Day, Month and Year option elements within [tag:facebook] landing page https://www.facebook.com/ you you need to use WebDriverWait for the elementToBeClickable() and you can use the following Locator Strategies.
Options from Day Dropdown using id attribute:
WebElement dayElement = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.id("day")));
Select selectDay = new Select(dayElement);
List<WebElement> dayList = selectDay.getOptions();
for (int i=0; i<dayList.size(); i++)
System.out.println(dayList.get(i).getText());
Options from Month Dropdown using [tag:xpath] and [tag:java-8] stream() and map():
Select selectMonth = new Select(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//select[@id='month']"))));
List<String> myMonths = selectMonth.getOptions().stream().map(element->element.getText()).collect(Collectors.toList());
System.out.println(myMonths);
Console Output:
[Month, Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sept, Oct, Nov, Dec]
Options from Month Dropdown using [tag:css_selectors] and [tag:java-8] stream() and map() in a single line of code:
System.out.println(new Select(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("select#year")))).getOptions().stream().map(element->element.getText()).collect(Collectors.toList()));
Console Output:
[Year, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 1996, 1995, 1994, 1993, 1992, 1991, 1990, 1989, 1988, 1987, 1986, 1985, 1984, 1983, 1982, 1981, 1980, 1979, 1978, 1977, 1976, 1975, 1974, 1973, 1972, 1971, 1970, 1969, 1968, 1967, 1966, 1965, 1964, 1963, 1962, 1961, 1960, 1959, 1958, 1957, 1956, 1955, 1954, 1953, 1952, 1951, 1950, 1949, 1948, 1947, 1946, 1945, 1944, 1943, 1942, 1941, 1940, 1939, 1938, 1937, 1936, 1935, 1934, 1933, 1932, 1931, 1930, 1929, 1928, 1927, 1926, 1925, 1924, 1923, 1922, 1921, 1920, 1919, 1918, 1917, 1916, 1915, 1914, 1913, 1912, 1911, 1910, 1909, 1908, 1907, 1906, 1905]

这种方法可能会帮助您理解如何从下拉菜单中获取所有可选选项。
driver.navigate().to("https://the-internet.herokuapp.com/");
WebDriverWait wait = new WebDriverWait(driver, 10, 100);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//a[@href='/dropdown']"))).click();
WebElement element = driver.findElement(By.xpath("//select[@id='dropdown']"));
Select select = new Select(element);
List<WebElement> allOptions = select.getOptions();
allOptions.forEach(value -> { System.out.println(value.getText()); });
