Animation | PrimeFaces JavaScript API Docs

The promise will be resolved when the animation reaches its end, and rejected when terminated early. The context of callbacks attached to the promise will be the element, and the arguments will be the Animation object and a boolean jumpedToEnd which when true means the animation was stopped with gotoEnd, when undefined the animation completed naturally.

deprecated
Deprecated since 1.8. Use ``.

Cause: The .pipe() method on a jQuery.Deferred object was deprecated as of jQuery 1.8, when the .then() method was changed to perform the same function.

Solution: In most cases it is sufficient to change all occurrences of .pipe() to .then(). Ensure that you aren't relying on context/state propagation (e.g., using this) or synchronous callback invocation, which were dropped from .then() for Promises/A+ interoperability as of jQuery 3.0.

example
````Filter resolve value:
```
var defer = $.Deferred(),
filtered = defer.pipe(function( value ) {
return value * 2;
});

defer.resolve( 5 );
filtered.done(function( value ) {
alert( "Value is ( 2*5 = ) 10: " + value );
});
```
example
````Filter reject value:
```
var defer = $.Deferred(),
filtered = defer.pipe( null, function( value ) {

defer.reject( 6 );
filtered.fail(function( value ) {

deprecated
Deprecated since 1.8. Use ``.

Cause: The .pipe() method on a jQuery.Deferred object was deprecated as of jQuery 1.8, when the .then() method was changed to perform the same function.

Solution: In most cases it is sufficient to change all occurrences of .pipe() to .then(). Ensure that you aren't relying on context/state propagation (e.g., using this) or synchronous callback invocation, which were dropped from .then() for Promises/A+ interoperability as of jQuery 3.0.

progress

Inherited from Promise3.progress

Add handlers to be called when the Deferred object generates progress notifications.

see
``

since

Parameters
- progressCallback: TypeOrArray<CallbackBase<JQuery.Animation<TElement>, number, number, never>>
  
  A function, or array of functions, to be called when the Deferred generates progress notifications.
- Rest ...progressCallbacks: TypeOrArray<CallbackBase<JQuery.Animation<TElement>, number, number, never>>[]
  
  Optional additional functions, or arrays of functions, to be called when the Deferred generates progress notifications.
Returns JQuery.Animation<TElement>

promise

promise<TTarget>(target: TTarget): JQuery.Animation<TElement> & TTarget
promise(): JQuery.Animation<TElement>

Return a Deferred's Promise object.

since

1.5

example

````Create a Deferred and set two timer-based functions to either resolve or reject the Deferred after a random interval. Whichever one fires first "wins" and will call one of the callbacks. The second timeout has no effect since the Deferred is already complete (in a resolved or rejected state) from the first timeout action. Also set a timer-based progress notification function, and call a progress handler that adds "working..." to the document body.

function asyncEvent() {
var dfd = jQuery.Deferred();

// Resolve after a random interval
setTimeout(function() {
dfd.resolve( "hurray" );
}, Math.floor( 400 + Math.random() * 2000 ) );

// Reject after a random interval
setTimeout(function() {
dfd.reject( "sorry" );
}, Math.floor( 400 + Math.random() * 2000 ) );

// Show a "working..." message every half-second
setTimeout(function working() {
if ( dfd.state() === "pending" ) {
dfd.notify( "working... " );

Type Parameters

TTarget extends object

Parameters

target: TTarget

Object onto which the promise methods have to be attached

Returns JQuery.Animation<TElement> & TTarget

Return a Deferred's Promise object.

example

````Use the target argument to promote an existing object to a Promise:

// Existing object
var obj = {
hello: function( name ) {

// Create a Deferred
defer = $.Deferred();

// Set object as a promise
defer.promise( obj );

// Use the object as a Promise
obj.done(function( name ) {

}).hello( "Karl" ); // Will alert "Hello Karl"

state

state(): "pending" | "resolved" | "rejected"

Inherited from Promise3.state

Determine the current state of a Deferred object.

see
``

since
