注：driver为一个WebDriver的实例,xpath为一个元素的xpath字符串，在本文中一律采用xpath的方式定位元素
1、鼠标右键点击操作：
Actions action = new Actions(driver) ;
action.contextClick(driver.findElement(By.xpath(xpath))) ;
2、鼠标左键双击操作：
Actions action = new Actions(driver) ;
action.doubleClick(driver.findElement(By.xpath(xpath))) ;
3、鼠标左键按下操作：
Actions action = new Actions(driver) ;
action.clickAndHold(driver.findElement(By.xpath(xpath))) ;
4、鼠标左键抬起操作：
Actions action = new Actions(driver) ;
action.release(driver.findElement(By.xpath(xpath))) ;
5、鼠标移动到元素上操作：
Actions action = new Actions(driver) ;
action.moveToElement(driver.findElement(By.xpath(xpath))) ;
6、组合的鼠标操作（将目标元素拖拽到指定的元素上）：
Actions action = new Actions(driver) ;
action.dragAndDrop(driver.findElement(By.xpath(xpath)),driver.findElement(By.xpath(xpath))) ;
7、组合的鼠标操作（将目标元素拖拽到指定的区域里）：
Actions action = new Actions(driver) ;
action.dragAndDrop(driver.findElement(By.xpath(xpath)),xOffset,yOffset) ;
8、键盘的按下操作：
Actions action = new Actions(driver) ;
action.keyDown(driver.findElement(getBy()),key) ;注：key 为一个Keys的实例，实例化一个F1的按键则为Keys.F1
9、按钮松开操作：
Actions action = new Actions(driver) ;
action.keyUp(driver.findElement(getBy()),key) ;
