查询后发现该方法已经被弃用，需要用find\_element()方法替代，使用方法如下：

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA5p2O5bCP5oGp5oGp5a2Q_size_18_color_FFFFFF_t_70_g_se_x_16][]

driver.find_element(By.ID,"J_goodsList")
    #想查的是id就写By.ID，是class就写CLASS_NAME
    #感觉变动不是很大，也还挺方便

find\_element()方法的源码如下：

def find_element(self, by=By.ID, value=None):
            """
            Find an element given a By strategy and locator.
    
            :Usage:
                ::
    
                    element = element.find_element(By.ID, 'foo')
    
            :rtype: WebElement
            """
            if by == By.ID:
                by = By.CSS_SELECTOR
                value = '[id="%s"]' % value
            elif by == By.TAG_NAME:
                by = By.CSS_SELECTOR
            elif by == By.CLASS_NAME:
                by = By.CSS_SELECTOR
                value = ".%s" % value
            elif by == By.NAME:
                by = By.CSS_SELECTOR
                value = '[name="%s"]' % value
    
            return self._execute(Command.FIND_CHILD_ELEMENT,
                                 {"using": by, "value": value})['value']

最后记得导入这个包：
