What are the jquery sliding events?

jquery sliding events include: 1. The "slideDown()" element slides down to open, and the height and marginTop value are set for the element during the conversion process; 2. The "slideUp()" element slides up to close, and the element is hidden At the same time, gradually reduce the height and marginTop values; 3. "slideToggle()" switches the state of the element, automatically determines the state and calls the method.

The operating system of this tutorial: Windows 10 system, jQuery3.6.0 version, Dell G3 computer.

jQuery has multiple sliding events, the following are some of them:

1, `slideDown()`

The element slides down to open

```javascript
$(selector).slideDown(speed,callback);
```

2, `slideUp()`

The element slides up to close

```javascript
$(selector).slideUp(speed,callback);
```

3, `slideToggle()`

Toggle the state of the element (on or off)

 ```javascript
 $(selector).slideToggle(speed,callback);
 ```

The form of these event codes is very similar. They all take a jQuery selector as a parameter, followed by an animation speed value and/or a callback function as optional parameters.

All these swipe events have different functions. `slideDown()` slides an element from the hidden state to the displayed state, while `slideUp()` slides the element from the displayed state to the hidden state. `slideToggle()` is more flexible and can toggle elements on or off based on their current state.

In addition, `.slideDown()`, `.slideUp()`, and `.slideToggle()` provide support for the left and right angled transition trigger and completion callback events. You can use the `.stop()` method to stop a running animation. You can customize the callback function and set properties that need to change dynamically.

It will also be different when used in code. The `slideDown()` method gradually converts the target element from the hidden state to the displayed state, and sets the height and marginTop value for the element during the conversion process; while `slideUp ()`, on the contrary, gradually reduces the height and marginTop values ​​​​while the element is hidden, and finally fully hides it. The `slideToggle` method will automatically determine the status and call one of the `slideUp()` or `slideDown()` methods.

Therefore, when using jQuery sliding events, it is necessary to clarify their roles and how to adapt to different pages, animation effects, interaction requirements, etc., in order to choose appropriate sliding events to achieve a better user experience.
