如何在python selenium中单击按钮后在网页上找到元素
提问于 2021-11-22 15:01:57
我是一个新的Python程序员。最近，我开始从事自动化/刮擦工作。目前，我被困在一种情况下，一个页面出现在按钮后，我无法找到该页面上的元素。
from selenium import webdriver
from selenium.webdriver.support.ui import Select
import time
driver = webdriver.Chrome(r"/Users/prateep/Downloads/chromedriver")
driver.get("https://example.com")
driver.maximize_window()
time.sleep(10)
button = driver.find_element_by_class_name("a-IRR-buttons")
button.click()
time.sleep(5)
driver.find_element("P52_NAME").send_keys("Test!!!")
selectStatus = Select(driver.find_element("P52_ASSESSMENT_STATUS_ID"))
selectStatus.select_by_value("O - Open")
driver.close()输出：-
driver.find_element_by_name("P52_NAME").send_keys("Test!!!")
Traceback (most recent call last):

问题在这条线上
driver.find_element("P52_NAME").send_keys("Test!!!")你使用find_element是错误的。
让我们看看在find_element内部有什么
def find_element(self, by=By.ID, value=None):
"""
Find an element given a By strategy and locator. Prefer the find_element_by_* methods when
possible.
:Usage:
element = driver.find_element(By.ID, 'foo')
:rtype: WebElement
"""
if self.w3c:
if by == By.ID:
by = By.CSS_SELECTOR
value = '[id="%s"]' % value
elif by == By.TAG_NAME:
by = By.CSS_SELECTOR
elif by == By.CLASS_NAME:
by = By.CSS_SELECTOR
value = ".%s" % value
elif by == By.NAME:
by = By.CSS_SELECTOR
value = '[name="%s"]' % value
return self.execute(Command.FIND_ELEMENT, {
'using': by,
'value': value})['value']正如你所看到的，我们必须用它
By.IDBy.CLASS_NAMEBy.TAG_NAMEBy.LINK_TEXTBy.PARTIAL_LINK_TEXTBy.NAMEBy.CSS_SELECTORBy.XPATH
如果P52_NAME是名称，并且它是唯一的，并且在HTMLDOM中表示所需的元素，那么理想情况下您应该使用
driver.find_element(By.NAME, "P52_NAME").send_keys("Test!!!")请签入dev tools (Google )，如果我们在HTML DOM中有唯一的条目。
检查的步骤：
Press F12 in Chrome ->转到element部分-> do a CTRL + F ->，然后粘贴NAME并查看所需的element是否使用1/1匹配节点得到高亮显示。
更新：
wait = WebDriverWait(driver, 30)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.XPATH, "iframe xpath")))
wait.until(EC.visibility_of_element_located((By.ID, ""))).send_keys("")导入:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
