Selenium: mouse, keyboard events

Mouse events

1. The method click(), which simulates the "left click" of the mouse in Selenium, was introduced earlier. This method alone is not enough.Current Web products provide richer mouse interaction methods
⑴ ⑴ For example, functions such as right-click, double-click, hover, drag, etc.
⑵ Similarly, Selenium also provides corresponding methods to simulate these miceAction

2. In WebDriver, these methods of mouse operation are encapsulated in the ActionChains class.
⑴The first letter of the class name ActionChains needs to be capitalized

3. The mouse method under the ActionChains class needs to instantiate an ActionChains object before use, and finally use the perfrom() method to submit the action
⑴ ⑴Use the ActionChains object to call the mouse method under it

Perform action

1. Method name: perfrom()

2. The reason why this method should be introduced first is because the function of this method is to execute all the actions stored in ActionChains, which can be understood as the submission action for the entire operation
⑴ ⑴ That is to say : All mouse methods in the ActionChains class need to be submitted through this method

3. When the ActionChains class method (mouse operation method) is called, it will not be executed immediately, but all operations will be stored in a queue. When the perform() method is called, the operations in the queue will be executed sequentially
⑴ can be understood as the submission of mouse events

4. This method is used in combination with other mouse methods, so it will be demonstrated in the following examples

Left mouse click
