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 

这就是我想让我的webdriver等待被定位/可见。 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

通过一些瓦亭的时间到浏览器，直到CSS选择器是可见的（加载）。你也可以通过隐式等待功能或使用

Wait.until()
