引言:
Selenium的显性等待,其常用的定位方法介绍,后面持续更细具体用法
示例如下:
python
<input type="text" class="s_ipt" name="wd" id="kw" maxlength="100" autocomplete="off">
ID定位
python
wait.until(EC.visibility_of_element_located((By.ID, 'kw')))
Name定位:
python
wait.until(EC.visibility_of_element_located((By.NAME, 'wd')))
Class定位:
python
wait.until(EC.visibility_of_element_located((By.CLASS_NAME, 's_ipt')))
Tag定位:
python
wait.until(EC.visibility_of_element_located((By.TAG_NAME, 'element_tag')))
Link Text定位:
python
wait.until(EC.visibility_of_element_located((By.LINK_TEXT, 'link_text')))
Partial Link Text定位: Link Text包含定位:
python
wait.until(EC.visibility_of_element_located((By.PARTIAL_LINK_TEXT, 'partial_link_text')))
CSS Selector定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, 'css_selector')))
XPath定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, 'xpath')))
层级定位:
python
parent_element = driver.find_element(By.XPATH, 'parent_xpath')
wait.until(EC.visibility_of_element_located((By.XPATH, 'child_xpath')), parent_element)
多个条件组合定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, 'xpath')) and EC.element_to_be_clickable((By.ID, 'element_id')))
标签属性定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, '//tag[@attribute="value"]')))
元素文本定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, '//*[text()="element_text"]')))
元素属性值包含定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '[attribute*="value"]')))
元素属性值以定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '[attribute^="value"]')))
元素属性值结尾定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '[attribute$="value"]')))
元素文本包含定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, '//*[contains(text(), "element_text")]')))
属性值正则匹配定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, '//*[matches(@attribute, "regex_pattern")]')))
子元素定位:
python
parent_element = driver.find_element(By.XPATH, 'parent_xpath')
wait.until(EC.visibility_of_element_located((By.XPATH, 'child_xpath')), parent_element)
元素索引定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, '(//tag)[index]')))
兄弟元素定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, 'preceding-sibling::tag')))
父元素定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, 'parent::tag')))
祖先元素定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, 'ancestor::tag')))
子元素索引定位:
python
wait.until(EC.visibility_of_element_located((By.XPATH, 'parent_xpath/tag[index]')))
元素属性值不等于定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '[attribute!="value"]')))
元素属性值包含多个定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '[attribute~="value1"][attribute~="value2"]')))
元素属性值开始定位:
python
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '[attribute^="value"]')))
以上是常用selenium的基本定位的方法,后面持续更新具体结合实际操作用法
