9 Python+Selenium鼠标事件

【环境信息】

python3.6+Selenium3.0.2+Firefox50.0+win7

【ActionChains类鼠标事件的常用方法】

1、右击：context_click()

2、双击：double_click()

3、拖动：drag_and_drop()

4、鼠标悬停在一个元素上：move_to_element()

5、按下鼠标左键在一个元素上：click_and_hold()

【问题】

在调用perform()方法时报错，不知道是不是环境配置问题，调用ActionChains中的click方法或者把perfom中的action方法去掉后不会报错，但是达不到效果。

报错信息：

代码：

    def testRightClick(self):
        self.MousOperate()
        #定位右击的元素,并且多选元素进行右击操作
        elements = self.driver.find_element_by_xpath("//div[@class='list-view']/dd[1]/div[2]/div[2]/div")
        elements = self.driver.find_element_by_xpath("//div[@id='layoutMain']")
        #print(elements.get_attribute('class'))
        time.sleep(2)
        ActionChains(self.driver).context_click(elements).perform()
        time.sleep(5)
