使用硒通过ID在Python测试

Question

获得元素在下面我的html代码：

<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> 

我要选择退出按钮，这实际上是出现在我的导航栏中选择。

我试图通过名称，id等获取元素，但没有解决。

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

我明确地在注销的href链接中添加了id，但无法获取该元素。任何建议我怎样才能注销元素

我得到以下异常：

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

Answer 1

从Selenium/Firefox: Command ".click()" doesn't work with a found element

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") 

Answer 2

您是否尝试过使用从UI支持Select（类selenium.webdriver得到这个.support.select.Select（webelement））？

我不知道Python的很好，所以我的例子是在Java中：

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