python selenium - webdriver等到css_Selector可见

Question

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

这就是我希望我的webdriver等待定位/可见的内容。 我该怎么做？

Answer 1

使用WebDriverWait with the visibility_of_element_located 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wating时间传递给浏览器，直到CSS选择器可见（加载）。您也可以通过隐式等待函数传递或使用

 Wait.until()
