本节重点: ActionChains 类 context_click() 右击 double_click() 双击 drag_and_drop() 拖动
测试的产品中有一个操作是右键点击文件列表会弹出一个快捷菜单,可以方便的选择快捷菜单中的选择对文件进行操作(删除、移动、重命名),之前学习元素的点击非常简单: driver.find_element_by_id(“xxx”).click() 那么鼠标的双击、右击、拖动等是否也是这样的写法呢?例如右击: driver.find_element_by_id(“xxx”).context_click() 经过运行脚本得到了下面的错误提示: AttributeError: 'WebElement' object has no attribute 'context_click' 提示右点方法不属于webelement 对象,通过查找文档,发现属于ActionChains 类,但文档中没有具体写法。这里要感谢 北京-QC-rabbit 的指点,其实整个python+selenium 学习过程都要感谢 北京-QC-rabbit 的指点。
下面介绍鼠标右键的用法,以快播私有云为例: ![]() ![]() 这里需要注意的是,在使用ActionChains 类之前,要先将包引入。
右击的操作会了,下面的其它方法比葫芦画瓢也能写出来。 鼠标双击的写法: #定位到要双击的元素 qqq =driver.find_element_by_xpath("xxx") #对定位到的元素执行鼠标双击操作 ActionChains(driver).double_click(qqq).perform()
鼠标拖放操作的写法: ![]() ![]()
ActionChains 类不仅仅是只包含了上面的三个方法,下面将方法列出: class ActionChains(driver) driver:The WebDriver instance which performs user actions. Generate user actions. All actions are stored in the ActionChains object. Call perform() to fire stored actions.
– perform() Performs all stored actions.
– click(on_element=None) Clicks an element. on_element:The element to click. If None, clicks on current mouse position.
– click_and_hold(on_element) Holds down the left mouse button on an element. on_element:The element to mouse down. If None, clicks on current mouse position.
– context_click(on_element) Performs a context-click (right click) on an element. on_element:The element to context-click. If None, clicks on current mouse position.
– double_click(on_element) Double-clicks an element. on_element:The element to double-click. If None, clicks on current mouse position.
– drag_and_drop(source, target) Holds down the left mouse button on the source element, then moves to the target element and releases the mouse button. source:The element to mouse down. target: The element to mouse up.
– key_down(key, element=None) Sends a key press only, without releasing it. Should only be used with modifier keys (Control, Alt andShift). key:The modifier key to send. Values are defined in Keys class. element:The element to send keys. If None, sends a key to current focused element. – key_up(key, element=None) Releases a modifier key. key:The modifier key to send. Values are defined in Keys class. element:The element to send keys. If None, sends a key to current focused element.
– move_by_offset(xoffset, yoffset) Moving the mouse to an offset from current mouse position. xoffset:X offset to move to.yoffset:Y offset to move to.
– move_to_element(to_element) Moving the mouse to the middle of an element. to_element: The element to move to.
– move_to_element_with_offset(to_element, xoffset, yoffset) Move the mouse by an offset of the specificed element. Offsets are relative to the top-left corner of the element. to_element: The element to move to.xoffset:X offset to move to.yoffset:Y offset to move to.
– release(on_element) Releasing a held mouse button. on_element:The element to mouse up.
– send_keys(*keys_to_send) Sends keys to current focused element. keys_to_send:The keys to send.
– send_keys_to_element(self, element,*keys_to_send): Sends keys to an element. element:The element to send keys.keys_to_send:The keys to send. |
