Selenium WebDriver

下载每个浏览器对应的驱动，并放到PATH变量下，或者通过修改executable_path参数来解决

Firefox驱动

geckodriver 0.24.0 ( 2019-01-28)

The source code of this program is available from
testing/geckodriver in https://hg.mozilla.org/mozilla-central.

Chrome 驱动

下载跟你的浏览器对应的版本

ChromeDriver 74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29})

元素定位

chrome的定位技巧，在console下可以执行两个特别的函数

$x('xpath表达式')
$x('//*[@data-toggle="dropdown" and @class="btn btn-default"]')
$x('//*[text()[contains(., "目录")]]')

$('css表达式')
$('.toc-container .btn.btn-default')
$('.btn.btn-default[data-toggle=dropdown]')

js定位
document.getElementById
document.getElementsByXXX

css定位表达式学习：https://www.w3schools.com/cssref/css_selectors.asp
XPath定位： XPath Syntax
