selenium webdriver在带有firefox浏览器的无头Linux上使用python在下拉菜单中选择一个选项

Question

我有以下代码：

#!/usr/bin/env python
from pyvirtualdisplay import Display
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.support.ui import Select
from pyquery import *
# declaration of variables
display = Display(visible=0, size=(800, 600))
display.start()
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
# Initialize
driver = webdriver.Firefox(capabilities=firefox_capabilities)
driver.maximize_window()
driver.implicitly_wait(10)
driver.get('https://sjobs.brassring.com/TGWebHost/searchopenings.aspx?partnerid=25222&siteid=5011')
print driver.title
# below does not work
# driver.find_element_by_xpath(".//*[@id='Question4138__FORMTEXT62']/option[37]").click()
# selectsoptions = driver.find_element_by_id("Question4138__FORMTEXT62")
# for option in selectsoptions .find_elements_by_tag_name('option'):
  # if option.text == 'Calgary':
    # option.select()
    # break
driver.find_element_by_id('ctl00_MainContent_submit1').click()
# call a sub-routine function def (not shown here)
save_rows(driver.find_element_by_id('idSearchresults'))
driver.close()
display.stop()

输出：

“寻找工作-沃尔玛加拿大职业”

问题是，我不知道如何在“加拿大城市”字段中选择“卡尔加里”。我尝试了许多不同的方法，但仍然不起作用。你能帮忙吗？

注意：我可以选择选项，并且我的代码在非headless环境Windows机器中工作，这里是python selenium webdriver选择选项不工作。我现在处理的是无头Ubuntu，因此浏览器并没有在任何物理显示器上真正打开。

提前再次感谢。

测试溶液：

答案是使用PhantomJS无头Webkit浏览器，它将在Windows和Linux上使用完全相同的代码。下面是例子：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from pyquery import *
import json
import csv
import sys
import time

def save_rows(elements):
    rows = elements.find_element_by_id('idSearchresults_dataBody')
    for row in rows.find_elements_by_tag_name('tr'):
        link = row.find_element_by_css_selector('a').get_attribute('href')
        print link

driver = webdriver.PhantomJS(service_args=['--ssl-protocol=any'])
driver.implicitly_wait(10)
driver.get('https://sjobs.brassring.com/TGWebHost/searchopenings.aspx?partnerid=25222&siteid=5011')

text = "Calgary"
currentselection = driver.find_element_by_id("Question4138__FORMTEXT62")
select = Select(currentselection)
select.deselect_by_visible_text("All")
select.select_by_visible_text(text)

driver.find_element_by_id('ctl00_MainContent_submit1').click()

save_rows(driver.find_element_by_id('idSearchresults'))

driver.quit()

在这里，我会给你代码。请检查一下。

# -*- coding: utf-8 -*-

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.Chrome("chromedriver.exe")
driver.get("https://sjobs.brassring.com/TGWebHost/searchopenings.aspx?partnerid=25222&siteid=5011")
ele = driver.find_element_by_xpath("//option[contains(text(),'Calgary  ')]")
print ele
driver.execute_script("arguments[0].scrollIntoView()",ele)
time.sleep(2)
ele.click()
