有两个关键问题帮助我解决了这一问题：
- 不要使用我之前为您提供帮助的自定义等待
- 将第
window.document.body.scrollTop
一个设置为0，然后document.body.scrollHeight
连续设置为
工作代码：
results = []while len(results) < 200: results = driver.find_elements_by_css_selector("div.flightbox") print len(results) # scroll driver.execute_script("arguments[0].scrollIntoView();", results[0]) driver.execute_script("window.document.body.scrollTop = 0;") driver.execute_script("window.document.body.scrollTop = document.body.scrollHeight;") driver.execute_script("arguments[0].scrollIntoView();", results[-1])版本2 （无限循环，如果滚动条上没有任何内容，则停止）：
results = []while True: try: wait.until(wait_for_more_than_n_elements((By.CSS_SELECTOR, "div.flightbox"), len(results))) except TimeoutException: break results = self.driver.find_elements_by_css_selector("div.flightbox") print len(results) # scroll for _ in xrange(5): try: self.driver.execute_script(""" arguments[0].scrollIntoView(); window.document.body.scrollTop = 0; window.document.body.scrollTop = document.body.scrollHeight; arguments[1].scrollIntoView(); """, results[0], results[-1]) except StaleElementReferenceException: break # here it means more results were loadedprint "DONE. Result count: %d" % len(results)请注意，我已在
wait_for_more_than_n_elements预期条件下更改了比较。替换为：
return count >= self.count
与：
return count > self.count
版本3 （从页眉滚动到页脚多次）：
header = wait.until(EC.visibility_of_element_located((By.TAG_NAME, 'header')))footer = wait.until(EC.visibility_of_element_located((By.TAG_NAME, 'footer')))results = []while True: try: wait.until(wait_for_more_than_n_elements((By.CSS_SELECTOR, "div.flightbox"), len(results))) except TimeoutException: break results = self.driver.find_elements_by_css_selector("div.flightbox") print len(results) # scroll for _ in xrange(5): self.driver.execute_script(""" arguments[0].scrollIntoView(); arguments[1].scrollIntoView(); """, header, footer) sleep(1)
