在搜索框中输入文本，然后从 Auto Complete with Selenium 和 Python 中进行选择

Question

我正在尝试使用 selenium 和 python 在搜索框中输入一些文本。代码如下。如果选择“超级联赛”选项，它运行得非常好。虽然当输入此文本时，它作为预定义选项出现在框中加载一个新页面。我似乎无法复制这个

import time
from selenium import webdriver
from selenium.common.exceptions import NoSuchAttributeException
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select

browser = webdriver.Firefox()
browser.get("http://www.bbc.co.uk/sport/football/scores-fixtures")


try:
    elem = browser.find_element_by_class_name('sp-c-date-picker-timeline__item')
except:
    print('Was not able to find an element with that name.')

time.sleep(5)
elem.click()


try:
    elem2=browser.find_element_by_class_name('sp-c-search__input')
except:
    print('Not able to find an element with that name')

time.sleep(3)

elem2.send_keys('premier league')
time.sleep(2)

#searching for the text works but i can't select it

#elem2.send_keys(Keys.DOWN)
#time.sleep(2)
#elem2.send_keys(Keys.DOWN)
#time.sleep(2)
#elem2.send_keys(Keys.RETURN)
#elem2.submit()

elem2.select_by_visible_text('Premier League')

Answer 1

由于您尝试识别Search Box到classname，识别如下：

elem = browser.find_element_by_class_name('sp-c-date-picker-timeline__item')
#and
elem2=browser.find_element_by_class_name('sp-c-search__input')

这些定位器不能唯一标识Search Box。

对于input some text in a search box，您必须通过唯一的CSS 或XPATH 将占位符设置为Enter a team or competition 来识别Search Box，如下所示：

driver.find_element_by_xpath("//input[@id='sp-c-search__input']").send_keys("premier league")

最后，在文本为 Premier League 的选项上click()，您可以使用以下代码块：

suggestions = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located(By.XPATH,"//input[@id='sp-c-search__input']//following::div[@id='search-results']//ul/li/a/mark"))
for suggestion in suggestions :
    if suggestion.get_attribute("innerHTML").contains("Premier League") :
        suggestion.click()

更新

正如您所看到的错误：

NameError: name 'By' is not defined

确保您已添加以下所有导入：

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
