python webdriver等待直到css_Selector可见

Question

text = browser.find_element_by_css_selector('.dbaListing.listing.lastListing > td:nth-child(4) > span').text

这就是我想让我的webdriver等待定位/可见的东西。我该怎么做？

Answer 1

使用 Expected Condition

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

wait = WebDriverWait(browser, 10)
element = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".dbaListing.listing.lastListing > td:nth-child(4) > span")))
print(element.text)

Answer 2

将一些等待时间传递给浏览器，直到CSS选择器可见(加载)为止。您还可以隐式传递等待函数或使用

 Wait.until()
