Question

以下是测试用例：

#!/usr/bin/env python
from selenium import webdriver
from lxml.cssselect import CSSSelector
import selenium.webdriver.support.ui as ui
import time

def test(urlx):

    br = webdriver.PhantomJS('phantomjs')
    start_time = time.time()
    br.get(url)
    restaurant_url_sel = u'.restaurants a'
    ta_restaurant_button = br.find_element_by_css_selector(restaurant_url_sel)

    print str(ta_restaurant_button.text)

    elapsed_time = time.time() - start_time
    print("---|||||||||||||||||||||||||| %s seconds |||||||||||||||||||||||||||||||---" % elapsed_time)
    print br.page_source


url = 'http://www.tripadvisor.com/Tourism-g150812-Playa_del_Carmen_Yucatan_Peninsula-Vacations.html'
test(url)

追溯：

Traceback (most recent call last):
  File "scrapeall_destination.py", line 20, in <module>
get_restaurants(url)
  File "/Users/pablocastelo/Desktop/tripadvisor/get_restaurants.py", line 67, in get_restaurants

  raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotVisibleException: Message: {"errorMessage":"Element is not currently visible and may not be manipulated",

您可以看到的输出（我只包含页面源的相关部分）确实显示元素在那里，发生了什么？测试在Ubuntu上运行没有问题。

Answer 1

Wait表示元素 to be visible ：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


def test(urlx):
    br = webdriver.PhantomJS('phantomjs')
    br.get(urlx)

    ta_restaurant_button = WebDriverWait(br, 10).until(
        EC.visibility_of_element_located((By.CSS_SELECTOR, '.restaurants a'))
    )


url = 'http://www.tripadvisor.com/Tourism-g150812-Playa_del_Carmen_Yucatan_Peninsula-Vacations.html'
test(url)

Answer 2

你可以试试这个：

browser = webdriver.PhantomJS()
browser.set_window_size(1124, 850) # set browser size.
browser.get("http\:example.com") # Load page

解决方案是我们需要在执行browser.get（＆＃34;＆＃34;）之前设置虚假的浏览器大小。请参阅github
