Question

我只想在搜索按钮上搜索公司名称，键入公司名称，然后如果存在，我会尝试打开该公司的链接，但我尝试了很多方法，但总是会遇到问题。 .new抓取网页

我尝试过：

from selenium import webdriver

driver=webdriver.Chrome("C:/Users/RoshanB/Desktop/sentiment1/chromedriver_win32/chromedriver")

driver.get("http://www.careratings.com/brief-rationale.aspx")

但是现在我不知道如何单击“搜索公司名称”，键入公司名称并使用硒打开该公司链接

Answer 1

这应该对您有用，我已尝试使用id locator：

driver.maximize_window()

driver.get("http://www.careratings.com/brief-rationale.aspx")


search_company = driver.find_element_by_id("txtSearchCompany_brief")
search_company.send_keys("Abc India Limited:")

submit_button = driver.find_element_by_id("btn_submit").click()
submit_button.click()

但是，如果公司名称不可用，则必须编写代码。

尝试一下：

from selenium import webdriver
import time
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
from bs4.element import Tag

driver = webdriver.Chrome("C:/Users/RoshanB/Desktop/sentiment1/chromedriver_win32/chromedriver")
driver.get('http://www.careratings.com/brief-rationale.aspx')
time.sleep(4)

companyArray = []

try:
    search = driver.find_element_by_name('txtSearchCompany_brief')
    search.send_keys("Reliance Capital Limited")
    search.send_keys(Keys.RETURN)
    time.sleep(4)
    soup = BeautifulSoup(driver.page_source, 'lxml')
    companies = soup.find("table",class_="table1")

    for tag in companies.findChildren():
        if isinstance(tag, Tag) and tag.name in 'a' and tag.has_attr('href'):
            url_string = "http://www.careratings.com/"+tag['href'].replace (" ","%20")
""" **Open pdf file in new tab browser** """
            open_pdf(url_string)
            companyArray.append(tag.text)

except Exception as e:
    print(e)

driver.quit()
print(companyArray)

如果要取消公司名称，则需要安装 BeautifulSoup 软件包

pip install beautifulsoup4==4.7.1

位置：

txtSearchCompany_brief 是输入的搜索名称

表1 是搜索结果表类

如何单击搜索公司名称按钮，键入公司名称并使用Selenium和Python搜索？
