【Python】seleniumで待機する処理

昨日に続きseleniumネタ。

読み込まれるまで待機

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

def chrome():
   options = webdriver.ChromeOptions()
   options.binary_location = "/path/chrome"
  
   driver = webdriver.Chrome(
       executable_path="/path/chromedriver",
       chrome_options=options
   )
   return driver

driver = chrome()

# 最大待ち時間
wait_time = 10
wait = WebDriverWait(driver, wait_time)

# ページのすべての要素が読み込まれるまで待機（タイムアウトは１０秒）
wait.untile(EC.presence_of_all_elements_located)

# IDで指定した要素が読み込まれるまで待機
# ByIDの代わりにBy.CSS_SELECTOR → CSSセレクタ、By.XPATH → XPath
wait.untile(EC.presence_of_element_located((By.ID, "ID名")))

表示されるまで待機

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

def chrome():
   options = webdriver.ChromeOptions()
   options.binary_location = "/path/chrome"
  
   driver = webdriver.Chrome(
       executable_path="/path/chromedriver",
       chrome_options=options
   )
   return driver

driver = chrome()

# 最大待ち時間
wait_time = 10
wait = WebDriverWait(driver, wait_time)

# IDで指定した要素が表示されるまで待機
# ByIDの代わりにBy.CSS_SELECTOR → CSSセレクタ、By.XPATH → XPath
wait.untile(EC.visibility_of_element_located((By.ID, "ID名")))
