Finding element methods using the Webdriverwait encapsulation

For the selenium native lookup element method to encapsulate, in the timeout period within the specified time loop to find an element on the page

The benefits of this encapsulation:

1. Can effectively improve the search element of the small Lu, to avoid the element has not been loaded on the throw exception

2. Save time relative to Time.sleep and implictly_wait

3. Greatly reduce duplication of code, make use case writing more concise

Code:

#coding: Utf-8

#封装元素方法
From selenium import Webdriver
From Selenium.webdriver.support.ui import webdriverwait
From selenium.common.exceptions Import *
Import time
Class Base ():
def __init__ (self,driver):
Self.driver=driver

#查找元素
def find_element (self,locator): #locator参数是定位方式, such as ("id", "kw"), combine two parameters into one, * number is the two parameters to separate the value
Element=webdriverwait (self.driver,20,0.5). Until (Lambda x:x.find_element (*locator))
return element
#判断元素是否存在
def is_exists (Self,locator):
Try
Webdriverwait (self.driver,20,0.5). Until (Lambda x:x.find_element (*locator))
Return True
Except
Return False
#判断元素是否已经不存在, there is no return true, there is a return false
def element_is_disappeared (self,locator,timeout=30):
Is_disappeared=webdriverwait (self.driver,timeout,1, (elementnotvisibleexception)). Until_not (Lambda X:x.find_ Element (*locator). is_displayed ())
Print is_disappeared

#封装一个send_keys
def send_keys (Self,locator,text):
Self.find_element (Locator). Send_keys (text)

#封装一个click
def click (self,locator):
Self.find_element (Locator). Click ()

#运行主函数
If __name__== ' __main__ ':
Driver=webdriver. Chrome ()
Driver.get ("https://www.baidu.com")
#实例化
Base=base (Driver)
#定位输入框
input_loc= ("id", "kw")
#通过实例调用find_element来发送
Base.send_keys (Input_loc, "Selenium")
#点击按钮
button_loc= ("id", "su")
Base.click (Button_loc)

Time.sleep (3)
Driver.quit ()

* Method can be written according to the actual situation
