我想選擇頻道在下拉框使用selenimum webdriver（Python）的網頁。下面HTML給出：如何使用硒webdriver從下拉框中選擇

我有以下Python代碼：

driver.find_element_by_css_selector("#WLS_menu > span").click() 
    Select(driver.find_element_by_name("w_channel")).select_by_visible_text("12") 
    driver.find_element_by_name("Apply").click()

我收到以下錯誤：

File "netgear", line 23, in test_netge Select(driver.find_element_by_name("w_channel")).select_by_visible_text("12") 
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response 
     raise exception_class(message, screen, stacktrace) 
NoSuchElementException: Message: Unable to locate element: {"method":"name","selector":"w_channel"}

我失去了我的代碼的東西嗎？

是請使用XPath嘗試

driver.find_element_by_xpath("//*[@id='setting_2G']/table/tbody/tr[5]/td[2]/select").send_keys("12")

UPDATE

所以你必須切換到幀，則（請注意，我是一個java的傢伙，所以下面的答案是在java中的這種情況下， python將其更新爲python）

WebDriver driver = new FirefoxDriver(); 
driver.get("‪C:\\Users\\rajnish\\Desktop\\mytest.html"); 
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS); 
driver.switchTo().frame("page"); 
driver.findElement(By.xpath("//*[@id='setting_2G']/table/tbody/tr[5]/td[2]/select")).sendKeys("12");

從錯誤它看起來，它無法找到元素a首先使用名稱「w_channel」。 –

嗨耶謝謝，我已經更新了我的答案，請看看現在它是否工作 –

不工作。它引發此錯誤： NoSuchElementException：消息：無法找到元素：{「method」：「xpath」，「selector」：「// * [@ id ='setting_2G']/table/tbody/tr [5]/td [2]/select「} –
