Selenium Python如何等待select中的選項被填充？

Question

示例：要等待

<select id="myselect"></select> 

與

<option value="123">One-two-three</option> 

我怎麼能做到這一點在Python來填充？

Answer 1

您可以使用presence_of_element_located和explicit waiting用CSS選擇器來定位元素：

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.common.exceptions import TimeoutException 

try: 
    element = WebDriverWait(driver, 10).until(
     EC.presence_of_element_located((By.CSS_SELECTOR, "option[value='123']")) 
    ) 
    print("Option loaded") 
except TimeoutException: 
    print("Time exceeded!")
