[Selenium][Notes]Day2:八种元素定位方式

与name有关的有三种:

• name:使用name属性值来定位
• class name:使用cass属性值来定位
• tag_name:使用标记名称来定位

与Iink相关的有两种:

• link text:使用超级链接的全部文本来定位
• partitial_link_text:使用超级链接的部分文本来定位

与id有关:

• id:使用id属性值来定位

全能:

• xpath:使用 xpath表达式来定位
• css selector:使用css表达式来定位

语法格式: find_element_by_xxx

Code:
