javascript - 在搜索框中输入文本，然后选择使用 Selenium 和 Python 自动完成

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“ super 联赛”选项，它运行得非常好。虽然输入此文本时，它会作为预定义选项出现在框中，但我无法根据需要选择并单击它...如果您正在浏览网页，则可以单击“英超联赛”选项，然后它加载新页面。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

正如您尝试通过classname标识搜索框一样，如下所示:

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地标识搜索框。

要在搜索框中输入一些文本，您必须通过占位符设置为输入团队或比赛来识别搜索框独特的 CSS 或 XPATH 如下:

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

最后，要在文本为 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
