WebDriverWait顯示等待及隱式等待

selenium學習筆記：

WebDriverWait：顯式等待，針對某個元素進行等待，結合expected_conditions 使用，expected_conditions下掛條件眾多，主要有以下幾種：

EC.frame_to_be_available_and_switch_to_it(locator)   #判斷frame是否可以切換到當前定位地點

EC.text_to_be_present_in_element_value() #判斷指定元素的屬性值中是否包含了預期的字符串，返回布爾值

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

driver= webdriver.Firefox()
driver.get("https://www.baidu.com/")
locator=(By.ID,"kw")
#判斷是否找到element，並返回元素
element = WebDriverWait(driver,5,1).until(EC.presence_of_element_located((By.ID,"kw")))
element.send_keys("selenium")

#判斷title是否是設定值，返回布爾值
re= WebDriverWait(driver,10).until(EC.title_is("百度一下，你就知道"))
print(re)

# 判斷元素是否可見，返回元素
re1=WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.ID,'su')))
print(re1)

time.sleep(4)
driver.quit()

 

implicitly_wait:隱式等待

#encoding:utf-8
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait

driver=webdriver.Firefox()

driver.get("https://www.baidu.com/")
driver.implicitly_wait(10)#隱式等待
input_=driver.find_element_by_id("kwss")
input_.send_keys("selenium")
driver.quit()
