无法在网页中找到文本字段

Question

我已经创建了代码

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("https://www.moneycontrol.com")
wait = WebDriverWait(driver, 20)
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--ignore-certificate-errors')
driver.get("https://www.moneycontrol.com")

inputElement = WebDriverWait(driver, 30).until(
    EC.visibility_of_element_located((By.XPATH, "    (//input[@id='search_str'])[1]")))
inputElement.send_keys('IOC')
inputElement.submit()

assert driver.title == 'IOC Share Price, IOC Stock Price, Indian Oil Corporation Ltd. Stock Price, Share Price, Live BSE/NSE, Indian Oil Corporation Ltd. Bids Offers. Buy/Sell Indian Oil Corporation Ltd. news & tips, & F&O Quotes, NSE/BSE Forecast News and Live Quotes'

driver.quit()

任何人都可以指导我们如何输入值并按回车键吗？

Answer 1

使用CSS选择器找到它。另外，添加等待：

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

wait = WebDriverWait(driver, 20)
wait.until(EC.element_to_be_clickable(
                (By.CSS_SELECTOR, '#form_topsearch>.txtsrchbox.FL')))
inputElement = driver.find_element_by_css_selector("#form_topsearch>.txtsrchbox.FL")
inputElement.send_keys("some input")

如果以上代码不起作用，请在 inputElement.send_keys() 之前添加 inputElement.click()。问题是 Selenium 不认为您的 search_str id 是唯一的。

此外，我认为您不需要在您的情况下使用 inputElement.submit()。搜索字段看起来不像一个表单。来自 Selenium 源代码：

def submit(self):
    """Submits a form."""
    if self._w3c:
        form = self.find_element(By.XPATH, "./ancestor-or-self::form")
        self._parent.execute_script(
            "var e = arguments[0].ownerDocument.createEvent('Event');"
            "e.initEvent('submit', true, true);"
            "if (arguments[0].dispatchEvent(e)) { arguments[0].submit() }", form)
    else:
        self._execute(Command.SUBMIT_ELEMENT)

Answer 2

这里已经有可行的解决方案，但是 Chrome:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait

options = Options()
options.add_argument('--ignore-certificate-errors')

driver = webdriver.Chrome(options=options)
driver.get("https://www.moneycontrol.com")

inputElement = WebDriverWait(driver, 30).until(
    EC.visibility_of_element_located((By.XPATH, "(//input[@id='search_str'])[1]")))
inputElement.send_keys('IOC')
inputElement.submit()

assert driver.title == 'IOC Share Price, IOC Stock Price, Indian Oil Corporation Ltd. Stock Price, Share Price, Live BSE/NSE, Indian Oil Corporation Ltd. Bids Offers. Buy/Sell Indian Oil Corporation Ltd. news & tips, & F&O Quotes, NSE/BSE Forecast News and Live Quotes'

driver.quit()

是否需要 Firefox？

Answer 3

options = Options()
options.add_argument('--ignore-certificate-errors')
options.page_load_strategy = 'eager'    
driver = webdriver.Chrome(ChromeDriverManager().install(),options=options)
wait = WebDriverWait(driver, 20)
driver.get("https://www.moneycontrol.com")
inputElement=wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#form_topsearch>.txtsrchbox.FL'))) 
inputElement.send_keys('IOC',Keys.ENTER)

您可以使用页面加载策略来停止长页面加载以单击输入，然后将 Keys.ENTER 发送到输入标签。当前使用

进入页面

information you’re about to submit is not secure Because this form is being submitted using a connection that’s not secure, your information will be visible to others.

然后使用

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#proceed-button'))).click()

哪个应该产生

导入

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
