WebDriverWait显示等待及隐式等待

selenium学习笔记：

WebDriverWait：显式等待，针对某个元素进行等待，结合expected_conditions 使用，expected_conditions下挂条件众多，主要有以下几种：

EC.frame_to_be_available_and_switch_to_it(locator)   #判断frame是否可以切换到当前定位地点

EC.text_to_be_present_in_element_value() #判断指定元素的属性值中是否包含了预期的字符串，返回布尔值

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")
#判断是否找到element，并返回元素
element = WebDriverWait(driver,5,1).until(EC.presence_of_element_located((By.ID,"kw")))
element.send_keys("selenium")

#判断title是否是设定值，返回布尔值
re= WebDriverWait(driver,10).until(EC.title_is("百度一下，你就知道"))
print(re)

# 判断元素是否可见，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:隐式等待

#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)#隐式等待
input_=driver.find_element_by_id("kwss")
input_.send_keys("selenium")
driver.quit()
