如何在selenium中模拟按钮单击？

Question

我目前正在学习硒。我试图模拟从url单击csv文件的按钮“https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries".

我做到了：

Right click the csv icon
Inspect and copy the full xpath

然后我使用了以下代码：

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

driver = webdriver.Chrome()

url = 'https://worldpopulationreview.com/countries/countries-by-gdp'
driver.get(url)

xpath = '/html/body/div[1]/div/div[1]/div[2]/div[2]/div[1]/div/div/div/div[2]/div[1]/a[2]'

btn = driver.find_element_by_xpath(xpath)
btn.click()

# df = pd.read_csv(os.path.expanduser('~/Downloads/data.csv'))
# print(df.head())
# driver.close()

WebDriverException: Message: unknown error: Element <a>...</a> is not clickable at point (1070, 879). Other element would receive the click: <div id="google_ads_iframe_/15184186/worldpopulationreview_adhesion_0__container__" style="border: 0pt none;">...</div>

尝试

我用不同的XPath尝试了多次，但都没有成功。如何模拟这个特定网站的按钮点击

Answer 1

有时候，如果有什么东西挡住了，selenium无法单击元素。在这种情况下，您可以使用javascript。但首先我会等待元素被点击

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

driver = webdriver.Chrome()

url = 'https://worldpopulationreview.com/countries/countries-by-gdp'
driver.get(url)

xpath = '/html/body/div[1]/div/div[1]/div[2]/div[2]/div[1]/div/div/div/div[2]/div[1]/a[2]'

# btn = driver.find_element_by_xpath(xpath)
btn = WebDriverWait(driver, 10).until(
        EC.element_to_be_clickable((By.XPATH, "//a[@download='csvData.csv']")))
driver.execute_script("arguments[0].click();", btn)
# btn.click()

# df = pd.read_csv(os.path.expanduser('~/Downloads/data.csv'))
# print(df.head())
# driver.close()

Answer 2

诱导WebDriverWait（）并等待element_to_be_clickable（）和下面的css选择器

driver.get("https://worldpopulationreview.com/countries/countries-by-gdp")
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,"a[download='csvData.csv']"))).click()

您需要导入以下库

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