在我下面的html代码中:

<div class="collapse navbar-collapse" id="b-menu-1">
                    <ul class="nav navbar-nav navbar-right">


                        <li><a href="/accounts/login/">Sign In</a></li>
                        <li><a href="/accounts/signup/">Sign Up</a></li>


                        {% if request.user.is_authenticated or logged_in %}
                        <li class="dropdown">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown">
                                <span class="glyphicon glyphicon-user"></span><b class="caret"></b></a>

                            <ul class="dropdown-menu">
                                <li><a href="/accounts/manageAccount/">Manage Account</a></li>
                                <li><a href="/accounts/createProfile/">create profile</a></li>
                                <li><a href="/accounts/viewProfile/">view profile</a></li>
                                <li><a href="/accounts/editProfile/">edit profile</a></li>  
                                <li><a href="/accounts/logout/" id="logout">Log out</a></li>
                            </ul>
                        </li>


                        <li data-toggle="modal" data-target="#my-modal-box" class="active">
                            <a href="#"><span class="glyphicon glyphicon-search"> Search</a></li>
                    </ul>
                </div> 

我想选择登出按钮,它实际上出现在我的导航栏的一个选择器中。

我尝试通过名称、ID等方式获取这个元素,但都没有成功。

elem2 = self.driver.find_element_by_id("logout")
elem2.send_keys(Keys.RETURN)

我在登出的链接中明确添加了ID,但还是无法抓取到这个元素。有什么建议可以让我获取到登出元素吗?

我遇到了下面的异常:

NoSuchElementException: Message: u'Unable to locate element: {"method":"id","selector":"logout"}' ; Stacktrace:

这个内容来自于 Selenium / Firefox: 命令 ".click()" 对找到的元素不起作用

def javascript_manual_click(driver, element_id):
    we = driver.find_element_by_id(element_id)
    driver.execute_script("arguments[0].click();", we)

javascript_manual_click("logout")

你有没有试过使用UI支持中的Select(类selenium.webdriver.support.select.Select(webelement))?

我对Python不太了解,所以我的例子是用Java写的:

    WebElement dropDownMenu = webDriver.findElement(By.xpath("//ul[@class='dropdown-menu']");
    Select logout = new Select(dropDownMenu);
    logout.selectByVisibleText("Log out");
