在python selenium中选择元素

我试图用python硒登录到网页。我发现了一个元素，它被启用，但是当我尝试send_keys（）给它时，我得到一个错误。最主要的（我认为）在错误输出在python selenium中选择元素

selenium.common.exceptions.ElementNotVisibleException: Message: Element is not currently visible and so may not be interacted with

我的代码是

from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 
import contextlib 

with contextlib.closing(webdriver.Firefox()) as driver: 
    driver.get('http://www.etoro.com/au') 
    elem = driver.find_element_by_class_name('inputUsername') 
    print 'enabled:', elem.is_enabled() 
    print 'selected:', elem.is_selected() 
    elem.send_keys('myusername')

，输出是

enabled: True 
selected: False 
Traceback (most recent call last): 
    File "3_trying_again.py", line 10, in <module> 
elem.send_keys('ianafterglow')

所以，我需要做什么？

试试这个ELEM =驱动程序。 find_element_by_class_name（'inputUsername'） action = webdriver.ActionChains（driver） action.click（elm）.perform（）; – 2014-12-02 08:20:48

在action.click（elem）.perform（）行上出现错误selenium.common.exceptions.ElementNotVisibleException：消息：元素当前不可见，因此可能不会与 – user2472657 2014-12-03 06:01:06

为了让用户名字段是可见的，你需要移动光标到登录链接：

.... 

driver.get('http://www.etoro.com/au') 
action = webdriver.ActionChains(driver) 
action.move_to_element(driver.find_element_by_xpath(
    './/a[@class="top-link"]/span[text()="Login"]' 
)) 
action.perform() 
# TODO Need to wait until the `inputUsername` field is visible 
elem = driver.find_element_by_class_name('inputUsername') 
...

交互''.// a [ @learn =“top_link”]/span [text（）=“Login”]'with selenium.common.exceptions.NoSuchElementException：Message：Unable to locate element：{“method”：“xpath”，“selector”：“ .// a [@class = \“top_link \”]/span [text（）= \“Login \”]“} – user2472657 2014-12-03 06:06:03

@ user2472657，我无法重现您的问题。代码工作没有错误。仅供参考，下面是我运行的确切代码：http://codepad.org/DfdPxwNG – falsetru 2014-12-03 06:12:26

问题是顶部链接中的下划线与连字符。多么尴尬！谢谢。 – user2472657 2014-12-04 01:43:10

您可以使用明确的等待：

from selenium.webdriver.common.by import By 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 

element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CLASSNAME, "inputUsername")) 
)

建议的修复代码成功运行，但程序以与selenium.common.exceptions.ElementNotVisibleException中的elem.send_keys（'myusername'）行最初相同的方式失败：消息：元素当前不可见，因此可能不是与之交互 – user2472657 2014-12-03 06:09:02

我知道，这个问题就解决了，我被困在类似的问题和相同的错误
我已经修复它只是让我的脚本睡2秒，然后恢复它只是连接速度问题

... 
time.sleep(2) 
...

不要忘了导入时间模块

import time

的愿望，以帮助大家在今后的：d

我有类似的问题，硒无法集中精力，打开登录模式。相反，它将重点放在下一个要素上。这是我用的定位：

elem = browser.find_element_by_xpath("//nav[2]/ul/li[3]/a").click()

我只是改变[3] [2]，它是能够找到的元素并打开模式：

elem = browser.find_element_by_xpath("//nav[2]/ul/li[2]/a").click()
