# 元素属性定位(3种)
driver.find_element_by_id(‘id’)
driver.find_element_by_name('name')
driver.find_element_by_class_name('class_name')
# 超链接定位(2种)
driver.find_element_by_link_text('link_text')
driver.find_element_by_partial_link_text('partial_link_text')
# 元素标签,元素路径,CSS选择器
driver.find_element_by_tag_name('tag_name')
driver.find_element_by_xpath('xpath')
driver.find_element_by_css_selector('css_selector')
但我们看下源码:
D:\Program Files\Python27\Lib\site-packages\selenium\webdriver\remote\webdriver.py
可以看到,上面那些定位方式,实际上都是调用的driver.find_element(by, value)
我们继续看下find_element()的源码,大部分方法最终全是通过By.CSS_SELECTOR来实现的查找
D:\Program Files\Python27\Lib\site-packages\selenium\webdriver\common\by.py
继续看源码,可以看到下面8种
ID = “id”
XPATH = “xpath”
LINK_TEXT = “link text”
PARTIAL_LINK_TEXT = “partial link text”
NAME = “name”
TAG_NAME = “tag name”
CLASS_NAME = “class name”
CSS_SELECTOR = “css selector”
所以我们以后就都只用find_element()就好了,因为最终实际上也都是调用的这个方法。
简单封装一下,以后就记住find_element()一个方法即可。

以后调用,先定义元素botton,在用例中查找时,调用方法即可
botton="id,su"
get_element(botton) # 页面上id为su的元素
