Python+selenium notes (14) Mouse and keyboard events

(i) Preface

Webdriver Advanced Application API allows us to simulate simple to complex keyboard and mouse events, such as drag-and-drop operations, shortcut key combinations, long presses, and right-click Actions, all by using the Actionchains class in the Webdriver Python API.

called The Actionchains class method is not executed immediately, but all operations are stored in a queue, and when the Perform () method is called, the operations in the queue execute sequentially

(ii) some important methods related to keyboard and mouse events

Method	Simple description
Click (on_element=none)	Click Element On_element: Refers to the element being clicked, if the parameter is none, the current mouse position is clicked
Click_and_hold (On_element=none)	Hold down the left mouse button on the element On_element: Refers to the element to hold down the left mouse button, and if the parameter is none, the current mouse position is clicked.
Double_click (On_element=none)	Double-click an element On_element: Whenever you double-click an element, if the parameter is none, click the current mouse position
Drag_and_drop (source, target)	Mouse drag Source: The element that the mouse drags Target: Mouse-released destination element
Key_down (value, Element=none)	Press and hold a key without releasing it for modifier keys (CTRL, ALT, and shift) Vakue: Refers to the key to hold, the value is defined in the Keys class element: The target element that is triggered by the key and, if none, is triggered at the current focus position.
Key_up (value, Element=none)	Release modifier keys Vakue: Refers to the key to hold, the value is defined in the Keys class element: The target element that is triggered by the key and, if none, is triggered at the current focus position.
Move_to_element (to_element)	Moves the mouse to the center of the specified element To_element: Specifying elements
Perform ()	Commit a saved action
Release (On_element=none)	Release mouse On_element: The element that is released by the mouse
Send_keys (Keys_to_send)	Keyboard action on the current focus element Keys_to_send: Input value of keyboard
Send_keys_to_element (element, Keys_to_send)	Keyboard action on the specified element Element: Specifying elements Keys_to_send: Input value of keyboard
