Event registration function On ()

Note: this is used to register events for the element. this in the listening function points to the element of the event registration, and an encapsulated event object is automatically imported to the first parameter of the listening function.

Syntax:H object. on (type, listener)

Parameter description:Type:String, the event type to be registered, without the on prefix. [Required]

Listener:Function, the listener Function to be registered. [Required]

Event object:

Note: The event object will be automatically passed in as the first parameter of the listener function. The event object is not a native time object, but a packaged time object, handling many compatibility issues, currently, the following attributes and methods are supported:

AltKey, ctrlKey, shiftKey, button, clientX, clientY, screenX, screenY, pageX, pageY, layerX, layerY, type, target, currentTarget, which, stopPropagation, preventDefault

The meaning and usage are the same as those of w3c standards.

Event logout Function Off ()

Events used to deregister Elements

Syntax:H object.Off ([Type[,Listener])

Parameter description:Type:String, the event type to be deregistered, without the on prefix. If this parameter is omitted, all types of events of the element are deregistered. [Optional]

Listener:Function, the listener Function to be deregistered. If this parameter is omitted, all listening functions of this type of event will be deregistered. [Optional]

Page event destruction Function H. off ()

Note: You can call this function to cancel all listening functions of all event types of all elements on the page. Simply put, all events of all elements on the page are removed.

Syntax:H. off ()No Parameter

Animation Functions Animate ()

Note: All functions registered on the same element constitute an animation queue. animation execution with no delay always takes precedence over delayed animation execution, A delayed animation is executed only after it is executed. If there are multiple delayed animations, the animation is executed based on the writing order and delayTime values.

Syntax:H object. animate (delay, delayTime, property, begin, change, time[, Type[, OutOrin[, Callback])

Parameter description:Dealy:Boolean: Specifies whether to delay animation execution. This parameter is equivalent to an animation queue. true indicates yes, and false indicates no. The delay indicates that the animation is executed after the previous animation is executed, on the same element, all animation without delay (that is, if this value is false) are executed simultaneously, and the delayed animation is executed after the animation is executed, if there are multiple delayed animations, the delayed animation in the order of writing is executed after the execution of the previous delayed animation is completed. Note: The latency effect only takes effect on the same element. [Required]

DelayTime:Number. value range: 0 ~ 1. specify a time point. When the animation arrives at this time point, the next animation in the queue will be executed. 0 indicates that the next animation will also be executed when the animation starts to be executed, 1 indicates that the next animation will be executed after the animation is executed. 0.5 indicates that the next animation will be executed when half of the animation is executed. If the animation is not delayed, the value is always 1. Note: This value affects the execution of the next animation in the queue and does not affect this animation. [Required]

Property: String: Specifies the animation attribute. Currently, the available attributes include width, height, top, left, right, bottom, opacity, and opacity. The value range is 0 ~ 1. [Required]

Begin: Number, the initial value of the property to be animated. [Required]

Change: Number, the amount to be changed, that is, a relative value. [Required]

Time: Number, which determines the animation time, in milliseconds. Generally, the value 100 is equivalent to about 1 second. [Required]

Type: String, easing type; optional value: "t0 "~ "T7", '"t0" indicates a uniform speed. The default value is "". [Optional]

OutOrin: String, slow in or slow out. The optional values are "o", "I", and "oi", which respectively indicate slow in, slow out, slow in and slow out. The default value is slow out. [Optional]

Callback: Function: the callback Function after the animation is executed [Optional]

 

Drag Function Drag ()

Note: after this method is called, the object has the mouse drag function.

Syntax:H object. drag (handle[, Parent[, Lock])

Parameter description:Handle: H object. This parameter specifies a drag-and-drop handle. It must be in the object to be dragged. If no handle is used, it is set to null. [Required]

Parent: H object, which specifies the parent element to be referenced (or ancestor element) by dragging the element. This element must be set to dynamic positioning. This parameter is generally used only when the drag element is limited to a certain range. [Optional]

Lock: Boolean. You must set the second parameter to use this parameter. "true" indicates that the drag range is restricted. "false" indicates that the drag range is not restricted. The default value is "true. [Optional]

Undrag Function Undrag ()

Note: after this method is called, the object cannot be dragged (provided that the drag () method is called before ).

Syntax:H object. undrag ()No Parameter

Hover ()

Description: This function is used to simulate mouse hover.

Syntax:H object.Hover (FunOver[, FunOut])

Parameter description:FunOver:Function: the Function to be executed when the cursor is over the element [required]

FunOut:Function, the Function to be executed when the mouse removes an element. If this parameter is omitted, the mouse removes the element without any action. [Optional]
