      selenium键盘按键Keys类及键盘码详解

      每篇文章努力于解决一个问题!python高级、python面试全套、操作系统经典课等可移步文章底部。

        selenium可以操作鼠标,此外它的Keys()类提供了操作键盘的途径,因为键盘上几乎所有按键都可以用Keys()类实现。 之前我们一直用元素的send_keys()方法输入文字,其实该方法也可以输入键盘的按键,按键就是Keys()类所提供。

        学习本文前你可以再回顾下提供键盘按键等交互行为的类ActionChains。其实在selenium之外还有基于python的键盘操作PyKeyboard模块,详情查看PyKeyboard按键操作

      from selenium.webdriver.common.keys import Keys
      

        一些元素对象具备send_keys方法,比如获取一个元素element后,直接调用element.send_keys('xxxx')方法。

        看起来挺简单,其实还是有一些注意事项,比如页面回到顶部或者回到底部的操作最好定位body元素执行按键,经过实测定位到其他元素甚至输入框上也可以实现下拉,但理论上总是感觉不放心(说不定某种情况就报错了),所以最好注意下。下节课我们上代码看一下定位到不同元素页面下拉的效果!此外,send_keys有时候丢失字符,具体解决请查看selenium坑合集

        本节课是理论,下节课是实操。常见的按键如下

      send_keys(Keys.SHIFT) shift键
      send_keys(Keys.CONTROL) ctrl键
      send_keys(Keys.ALT) alt键
      send_keys(Keys.PAGE_UP) PaUp键
      send_keys(Keys.PAGE_DOWN) PaDn键
      send_keys(Keys.UP) 上
      send_keys(Keys.DOWN) 下
      send_keys(Keys.LEFT) 左
      send_keys(Keys.RIGHT) 右
      send_keys(Keys.COMMAND)
      send_keys(Keys.BACK_SPACE) 删除键
      send_keys(Keys.SPACE) 空格键
      send_keys(Keys.TAB) 制表键
      send_keys(Keys.ESCAPE) 回退键
      send_keys(Keys.ENTER) 回车键
      send_keys(Keys.CONTROL,'a') 全选(Ctrl+A)
      send_keys(Keys.CONTROL,'c') 复制(Ctrl+C)
      send_keys(Keys.CONTROL,'x') 剪切(Ctrl+X)
      send_keys(Keys.CONTROL,'v') 粘贴(Ctrl+V)
      send_keys(Keys.F1)  F1键
      send_keys(Keys.F5)  F5键
      ……
      send_keys(Keys.F12) F12键
      

        Set of special keys codes.
