元素当前不可见，因此可能无法与Selenium下拉Box Python交互。
元素当前不可见，因此可能无法与Selenium下拉Box Python交互。
提问于 2016-01-24 17:57:54
我需要浏览我网页上的所有页面。在所有这些页面的左上角都有一个下拉框，其中有所有可用的城市。我想访问每一页，通过选择这个下拉框中的每一个位置。下拉框有一个滚动条，当我想选择它下面的选项时，它会给出异常消息：
Message: Element is not currently visible and so may not be interacted with

get_city_list(basic_url)我也试过用滚动条，试着向下移动，但仍然没有效果。我只能滚动这个下拉框顶部的页面：

the_file.write('\n')对于火狐，代码存在于元素'Gdańsk‘处，并带有一条消息:ń，这意味着它不会在我的组合框中找到每个元素。
对于Chrome和Windows，它存在于‘Bielskoła’，因此，这意味着它并不能在我的组合框中找到所有元素。..。
我怎样才能解决这个问题？

我试过用java，它的工作非常好。我请求看看循环主要是因为这里我可以选择一个一个的选项。我只是使用了Thread.sleep，因为我知道我们也可以使用等待。为了与我刚才附加到StringBuffer中的问题类似，我知道我们可以在java中添加到任何收集器中。我并没有像我说的那样被严格地跟踪到接受年龄等方面。
public class Dog {
private WebDriver driver;
private String baseUrl;
private StringBuffer verificationErrors = new StringBuffer();
@BeforeClass()
public void setUp() throws Exception {
// driver = new FirefoxDriver();
System.setProperty("webdriver.chrome.driver", "E:\\selenium_setups\\chromedriver_win32\\chromedriver.exe");
driver=new ChromeDriver();
driver.manage().window().maximize();
baseUrl = "http://example.com/";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
@Test
public void testStackoverflowIssue() throws Exception {
driver.get(baseUrl);
driver.findElement(By.cssSelector(".btn.btn-success")).click();
driver.get("http://example.com/ogloszenia-kobiet.html");
List<WebElement> options=driver.findElements(By.xpath(".//*[@id='select_city']/li/form/div/div/ul/li"));
for(int i=1; i<=options.size(); i++){
driver.findElement(By.xpath("(//button[@type='button'])[4]")).click();
driver.findElement(By.xpath("//ul[@id='select_city']/li/form/div/div/ul/li["+i+"]")).click();
driver.findElement(By.cssSelector("button.btn.btn-success")).click();
Thread.sleep(5000);
verificationErrors.append(driver.getCurrentUrl());
System.out.println(driver.getCurrentUrl() +" >>> iteration " +i);
driver.navigate().to("http://example.com/ogloszenia-kobiet.html");
Thread.sleep(5000);
}
}}
我希望这将有助于您在python中选择下拉值。
