带有selenium python库的按钮在站点中自动单击时不会执行任何操作

Question

这是在 GUI 中单击按钮后应运行的函数：

def button_event(self):
        drug1 = self.entry1.get()
        drug2 = self.entry2.get()


        chrome_driver_path = "Chrome driver path "

        # Set Chrome options to run in headless mode
        chrome_options = Options()

        # Create a new Chrome browser instance with the headless option
        browser = webdriver.Chrome(executable_path=chrome_driver_path, options=chrome_options)

        # Load the web page
        browser.get('https://go.drugbank.com/drug-interaction-checker')

        # Find the form element by ID
        form = browser.find_element(By.CSS_SELECTOR,'form.name-search-form')

        # Find the input fields and fill them out
        name_input = form.find_element(By.CSS_SELECTOR,'input.select2-search__field')
        name_input.send_keys(drug1)
        time.sleep(2)
        name_input.send_keys(Keys.RETURN)

        name_input.send_keys(drug2)
        time.sleep(2)
        name_input.send_keys(Keys.RETURN)
        time.sleep(2)
        button = form.find_element(By.ID,"search")
        time.sleep(4)
        if button.is_enabled():
            button.click()
            print("button is enabled")
        else :
            description = "Unfound medics in database"
            self.text1.delete("1.0","end")
            self.text1.insert("0.0", description)
            return
        wait = WebDriverWait(browser, 20)
        new_page_loaded = wait.until(EC.url_contains('drug-interaction-checker#results'))
        time.sleep(2)

        try:
            # Find the element 
            browser.find_element(By.CSS_SELECTOR,"h2.no-results")
            description = "No interaction found"
            self.text1.delete("1.0","end")
            self.text1.insert("0.0", description)
            return
        except NoSuchElementException:
            print("results are there")

        # Find the interactions div and extract the description text
        interactions_div = browser.find_element(By.CSS_SELECTOR,'div.interactions-col.description')
        description = interactions_div.find_element(By.TAG_NAME,'p').text
        self.text1.delete("1.0","end")
        self.text1.insert("0.0", description)

这应该打开

drugBank

网站并输入两个药物，然后单击该按钮检查交互，不知怎的，这不起作用，因为即使单击该按钮，即使手动也不会发生任何事情，但是当我自己进入该网站时，一切都发生了向右走。

Answer 1

抱歉，我的业力太低，无法发表评论，但我觉得这可能很有用。目前，当我使用 Firefox Web 浏览器手动单击该按钮时，没有任何反应。您的问题可能是由于手动测试与自动测试时浏览器/chrome 版本不同所致。

Answer 2

我将按钮单击替换为：

browser.execute_script(
    "document.getElementById('drug-interactions').submit();"
)

这样就不需要按钮了，一切都按预期工作。
