Ext. Element class

Element (string/htmlelement element, [Boolean forcenew])
Element Object created by ID or DOM Node

Element. Fly (string/htmlelement El, [String named]): Element
A global shared activity element is created by the ID or DOM node and can be named by named to avoid potential conflicts.

Element. Get (mixed El): Element
Obtain an Ext. Element object from the ID, Dom node, or an existing element.

Addclass (string/array classname): Ext. Element
Add one or more CSS class names to the element

Addclassonclick (string classname): Ext. Element
Add and remove CSS classes for click events

Addclassonfocus (string classname): Ext. Element
Add and remove CSS classes for getting and losing focus

Addclassonover (string classname, [Boolean preventflicker]): Ext. Element
Add and remove CSS classes for the move-in and remove event (this method does not actually use the preventflicker parameter)

Addkeylistener (number/array/Object/string key, function FN, [object scope]): Ext. keymap
Add a key for the object to listen to the key by a value or string or {key: (number or array), shift: (true/false), CTRL: (true/false), alt: (true/false)} these objects or their Arrays

Addkeymap (Object config): Ext. keymap
The function is the same as addkeylistener, but the parameter passing method is different.
El. addkeymap ({key: "AB", CTRL: True, FN: FN, scope: El });
El. addkeylistener ({key: "AB", CTRL: true}, FN, El );
It is equivalent to calling FN after pressing ctral + A or Ctrl + B.

addlistener (string eventname, function FN, [object scope], [object options]): void
defines event listening, eventname: event name, FN: event processing method, scrope: range. The options definition is complex and can contain the following attributes
scope {object}: Processing FN range
delegate {string }: A simple selector (filtering the target or finding the target's child node)
stopevent {Boolean}: blocks the event, which is equal to preventdefault + stoppropagation
preventdefault {Boolean }: stop default activity
stoppropagation {Boolean}: Stop event bubbling
normalized {Boolean}: Set to flase to allow browser events to replace Ext. eventobject
delay {number}: the number of milliseconds after the delay
single {Boolean}: run only once
buffer {number}: In Ext. util. scheduled Events in delayedtask
Of course, you may also customize parameters to pass in the function

Alignto (Mixed Element, string position, [array offsets], [Boolean/object animate]): Ext. Element
Alignment El to element and positon to indicate the alignment position. Optional.
TL upper left corner (default)
T Center
Tr upper right corner
L center of the left boundary
Center C
R center of the right boundary
BL lower left
Center under B
Bottom right corner of BR
Can position be used? Restricted movement cannot exceed the window
Offsets offset, in pixels
For details about animate, see the definition of animate.

Example: div1.alignto ('div2', 'c-Bl? ', [20, 0], true );
Use the default animation to align the center of div1 to the lower left corner of div2, and move 20 pixels to the right without exceeding the window.

Anchorto (Mixed Element, string position, [array offsets], [Boolean/object animate], [Boolean/number monitorscroll], function callback): Ext. Element
The function is similar to alignto, but it also triggers a realignto event when the window is redefined.
The monitorscroll parameter specifies whether to monitor the scroll bar behavior. If it is defined as a value, the delay is defined, in milliseconds. The default value is 50 ms,
Callback defines the call-back method after the completion of Animate

Animate (Object ARGs, [float duration], [function oncomplete], [String easing], [String animtype]): Ext. Element
Execute the animation.
ARGs: Target
Duration: Time Interval. The default value is 0.35.
Function: Call back method after completion
Easing: the default behavior method is easeout. The optional values are found in ext_base but not described. The following content is found in Yahoo UI.
Easenone: constant speed
Easein: starts slowly and accelerates
Easeout: starts fast and slows down
Easeboth: Start slowly and slow down
Easeinstrong: starts to slow and accelerates, the fourth power of T
Easeoutstrong: starts fast and slows down, the fourth power of T
Easebothstrong: starts to slow and slows down, the fourth power of T

Applystyles (string/Object/function styles): Ext. Element
Apply a style. Styles is a string such as "width: 100px" or an object such as {width: "100px"}. A function is a function that returns such a string and an object, this is a useless instruction, because any parameter passing can be a function of the required type. see also setstyle
