我有一个python脚本，它几乎可以工作，但有一个问题我无法解决。我的循环正在工作，但仅适用于第一行图像。由于某些原因，web元素在3个图像之后变得过时。我确信有3个以上的html元素与我的查询相匹配！我正在使用此脚本将元素带入视图driver.execute_script("arguments[0].scrollIntoView(true);", i)中。任何想法都将不胜感激。

这个特定的网站最初并没有加载所有的图像
因此，当您滚动到第二行中的图像时，仅会加载这些图像。这导致web元素发生变化，使得图片的初始列表downloadimg不再相关，在Selenium术语中是Stale elements
要使代码正常工作，您需要在每次滚动后再次获得downloadimg列表，如下所示：
downloadimg = WebDriverWait(driver,50).until(EC.presence_of_all_elements_located((By.XPATH, "//img[contains(@class,'new-grid-img')]")))
for i in downloadimg:
# bring the webelement into the viewport
driver.execute_script("arguments[0].scrollIntoView(true);", i)
downloadimg = driver.find_element_by_css_selector('img.new-grid-img')
time.sleep(2)
# determine element's location; the +190 and -100 is to make the mouse show ON the element rather than at it's border
location = i.location
size = i.size
x = location['x']+190
y = location['y']-100
# move to the element
pyautogui.moveTo((int(x), int(y)), duration=2)
time.sleep(2)
# right click
actions.context_click(i).perform()
# move to open in new browser tab
pyautogui.move(0, -25, duration=1)
time.sleep(1)
pyautogui.click()
# move to the new browser tab and click
pyautogui.moveTo(480, 50, duration=2)
pyautogui.click()
# give time to the img to load
time.sleep(4)
# move to the image and click
pyautogui.moveTo(780, 550, duration=2)
pyautogui.click()
# actions.context_click(i).perform()
# right click and mobe to save img as and then click
pyautogui.rightClick()
pyautogui.move(20, 200, duration=2)
pyautogui.click()
time.sleep(2)
# press enter in the dialog box to actually save the img to download folder
pyautogui.press('enter')
time.sleep(2)
# close the tab and go back to the beginning of the loop
pyautogui.hotkey('command', 'w')
您应该从代码中删除多余的driver.quit()以及
