Question

我尝试使用python selenium登录网页。我找到了一个元素并且它已启用，但是当我尝试send_keys（）时它会出错。错误输出中的主要内容（我认为）是

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

enabled: True
selected: False
Traceback (most recent call last):

那么，我需要做什么？

Answer 1

要使用户名字段可见，您需要将光标移动到登录链接：

....

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')
...

Answer 2

您可以使用显式等待：

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"))
)

...

Answer 3

我知道这个问题已经解决了，我陷入了类似的问题和同样的错误我修复它只是让我的脚本睡眠2秒然后恢复它只是连接速度问题

php -i | grep '\.ini'

不要忘记导入时间模块

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

希望将来帮助任何人：D

Answer 4

我有类似的问题，selenium无法关注并打开登录模式。相反，它专注于下一个元素。这是我使用的定位器：

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

我刚用[2]改变了[3]，它能够找到元素并打开模态：

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

在python selenium中选择元素
