Question

我用python和selenium编写了代码。它会点击show-more-results按钮一次。我已经使用了WebDriverWait，因此它允许页面加载但没有用。

for j in range(100):
    driver.find_element_by_xpath('.//div[@id="show-more-results"]').click()
    WebDriverWait(driver, 50).until(lambda driver : driver.find_element_by_xpath('.//div[@id="show-more-results"]'))

显示以下错误

Traceback (most recent call last):
  File "python23.py", line 20, in <module>
    driver.find_element_by_xpath('.//div[@id="show-more-results"]').click()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webelement.py", line 60, in click
    self._execute(Command.CLICK_ELEMENT)

从最后一个回答开始，我修改了脚本。你必须找到自己的条件来打破循环，我会找到最后一页中的一些元素，当你到达它时会中断。

import time
driver = webdriver.Firefox()
driver.get("http://www.flipkart.com/mobiles/pr?   p%5B%5D=sort%3Dfeatured&sid=tyy%2C4io&ref=659eb948-c365-492c-99ef-59bd9f0427c6")
time.sleep(3)
driver.maximize_window() # maximize window to see  elements
for i in range(4):
    print "Scrolling"
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);") # scroll to bottom of page
    time.sleep(4)
while True:  #
    try:
        print "Scrolling to bottom of page" # need to sroll to make show-more-results visible
        driver.execute_script("window.scrollTo(0, document.body.scrollHeight);") # scroll to bottom of page
        time.sleep(2)#   wait until you get to bottom of page to avoid "element not visible"
        print "Clicking show more results"
        driver.find_element_by_xpath('//*[@id="show-more-results"]').click()
        # click load more  button, needs to be done until you reach the end.
        time.sleep(10) # adjust sleep to suit your connection
    except Exception as e:
        print "This happened ",e
        print "Trying again"
        continue
elem=[]
elem=driver.find_elements_by_xpath('.//div[@class="pu-title fk-font-13"]')
for e in elem:
   print e.text

这是一个快速草案，你必须修改它，但应该让你更接近你想要做的事情。特别是如果您为网络断开连接，您希望打破该异常。

WebDriverWait（selenium）无效
