Question

我正在尝试使用Python和selenium包填写此homepage上的下拉菜单。选择让我使用以下代码

from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.support.select import Select

driver = webdriver.Firefox()
driver.implicitly_wait(5)
driver.get('http://www.tirerack.com/content/tirerack/desktop/en/homepage.html')

button = driver.find_element_by_tag_name('button')
ActionChains(driver).click(button).perform()

select_make = driver.find_element_by_id('vehicle-make')
Select(select_make).select_by_value("BMW")

然而，实际上并没有这样做＆＃34;选择BMW＆＃34;选项。我尝试按照this帖子中解释的方法进行操作。有人能告诉我我做错了吗？

从您链接到已接受答案的问题迭代选项并找到匹配的文本。

select_make = driver.find_element_by_id('vehical-make')
for option in select_make.find_elements_by_tag_name('option'):
    if option.text == 'BMW':
        option.click() # select() in earlier versions of webdriver
        break

在Java中运行我得到的信息是元素不可见，所以我强迫它：

    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.tirerack.com/content/tirerack/desktop/en/homepage.html");
    Thread.sleep(3000);

    driver.findElement(By.tagName("button")).click();

    WebElement select_make = driver.findElement(By.id("vehicle-make"));
    select_make.click();

    JavascriptExecutor js = (JavascriptExecutor) driver;
    String jsDisplay = "document.getElementById(\"vehicle-make\").style.display=\"block\"";
    js.executeScript(jsDisplay, select_make);

    for (WebElement option : select_make.findElements(By.tagName("option"))) {
        System.out.println(option.getText());
        if ("BMW".equals(option.getText())) {
            option.click();
            break;
        }
    }

如果你添加JavascriptExecutor行（在python中），我认为它会起作用。

使用selenium从动态下拉列表中选择选项
