元素定位的八種方式
- id : element = driver.find_element_by_id(id)
- name : element = driver.find_element_by_name(name)
- class_name : element = driver.find_element_by_class_name(class_name)
- tag_name : element = driver.find_element_by_tag_name(tag_name)
- link_text : element = driver.find_element_by_link_text(link_text)
- partial_link_text : element = driver.find_element_by_partial_link_text(partial_link_text)
- xpath : element = driver.find_element_by_xpath(xpath)
- css : element = driver.find_element_by_css_selector(css_selector)
- id, name, class: 基於元素的對應屬性去定位
- tag_name: 基於元素的標籤名稱
- link_text, partial_link_text: 基於鏈接文本定位
- xpath: 基於元素路徑定位
- css: 基於元素選擇器定位
元素的基本操作
- element.click() – 單擊元素
- element.send_keys(value) – 模擬輸入
- element.clear() – 清除文本
