This means that the driver would check the readiness of a target element at a 2-second interval. The polling begins again if the previous attempt fails. The wait ends once the target element is available, allowing other testing activities. Python has a polling2 module that is used to wait ...

1.until里面有个lambda函数,这个语法看python文档吧 2.以百度输入框为例 三、元素消失:until_not() 1.判断元素是否消失,是返回Ture,否返回False 备注:此方法未调好,暂时放这 四、参考代码: # coding:utf-8 from selenium import webdriver from selenium.webdriver.support.wait import WebDriverWait ...
Selenium2+python自动化38-显式等待(WebDriverWait) 前言: 在脚本中加入太多的sleep后会影响脚本的执行速度,虽然implicitly_wait()这种方法隐式等待方法一定程度上节省了很多时间。 但是一旦页面上某些js无法加载出来(其实界面元素经出来了),左上角那个图标一直转圈,这时候会一直等待的。

print('Enough of sleeping, I Quit!') Below short screen capture shows the complete program execution. Surprising, there is no easy way to wait for user input with a timeout or default value when empty user input is provided. I hope these useful features come in future Python releases....
