可以执行任何js
语法：driver.execute_script("js")
注意：Python代码和HTML代码保存在同一路径
案例：通过执行js，选中、取消选中、全选复选框。之后执行js判断是否全部选中，全选弹出“测试成功”，否则弹出“测试失败”
Python代码
#coding=utf-8
from selenium import webdriver
import time,os
file_path = os.path.abspath('checkbox.html')
print file_path
driver = webdriver.Chrome()
driver.get(file_path)
#通过执行js,选中复选框
driver.execute_script('var chk =document.getElementById("c1"); chk.checked="checked"')
print driver.find_element_by_id("c1").is_selected()
time.sleep(3)
#通过执行js,取消选中复选框
driver.execute_script('var chk =document.getElementById("c1"); chk.checked=""')
print driver.find_element_by_id("c1").is_selected()
time.sleep(3)
#通过执行js,全选所有复选框,执行的js可以定义函数，通过调用函数全选
driver.execute_script('var checkboxs=document.getElementsByTagName("input");
for (var i=0;i<checkboxs.length;i++)
{ var e=checkboxs[i];
if(e.type=="checkbox")
{e.checked="checked";
}
};')
time.sleep(3)
#判断是否全选，全选弹出“测试成功”，未全选弹出“测试失败”
driver.execute_script('function checkall()
{ var result=true;
var checkboxs=document.getElementsByTagName("input");
for (var i=0;i<checkboxs.length;i++)
{ var e=checkboxs[i];
if (e.type=="checkbox")
{if (!e.checked)
{ result=false;
continue;
}
}
}
if(result)
{ alert("测试成功");
}
else
{ alert("测试失败");
}
}
checkall()')
