Methods

setFocus ( )

Let the EditBox get focus, only valid when stayOnTop is true.

isFocused ( )

Determine whether EditBox is getting focus or not.

destroy ( )

if you don't need the EditBox and it isn't in any running Scene, you should call the destroy method on this component or the associated node explicitly. Otherwise, the created DOM element won't be removed from web page.

examples:

editbox.node.parent = null;  // or  editbox.node.removeFromParent(false);
// when you don't need editbox anymore
editbox.node.destroy();

_createSgNode ( ) _ccsg.Node private

Create and returns your new scene graph node (SGNode) to add to scene graph. You should call the setContentSize of the SGNode if its size should be the same with the node's.

returns:

type: _ccsg.Node

_initSgNode ( ) private

_removeSgNode ( ) private

update

  • dt
)
protected

Inherited from Component:

Update is called every frame, if the Component is enabled.

name type description
dt Number

lateUpdate ( ) protected

Inherited from Component:

LateUpdate is called every frame, if the Component is enabled.

__preload ( ) private

Inherited from Component:

__preload is called before every onLoad. It is used to initialize the builtin components internally, to avoid checking whether onLoad is called before every public method calls. This method should be removed if script priority is supported.

onLoad ( ) protected

Inherited from Component:

When attaching to an active node or its node first activated. onLoad is always called before any start functions, this allows you to order initialization of scripts.

start ( ) protected

Inherited from Component:

Called before all scripts' update if the Component is enabled the first time. Usually used to initialize some logic which need to be called after all components' onload methods called.

onEnable ( ) protected

Inherited from Component:

Called when this component becomes enabled and its node is active.

onDisable ( ) protected

Inherited from Component:

Called when this component becomes disabled or its node becomes inactive.

onDestroy ( ) protected

Inherited from Component:

Called when this component will be destroyed.

onFocusInEditor ( ) protected

Inherited from Component:

onLostFocusInEditor ( ) protected

Inherited from Component:

resetInEditor ( ) protected

Inherited from Component:

Called to initialize the component or node’s properties when adding the component the first time or when the Reset command is used. This function is only called in editor.

addComponent
(
  • typeOrClassName
)
Component

Inherited from Component:

Adds a component class to the node. You can also add component to node by passing in the name of the script.

name type description
typeOrClassName Function | String

the constructor or the class name of the component to add

returns:

type: Component

the newly added component

examples:

var sprite = node.addComponent(cc.Sprite);
var test = node.addComponent("Test");

getComponent
(
  • typeOrClassName
)
Component

Inherited from Component:

Returns the component of supplied type if the node has one attached, null if it doesn't.
You can also get component in the node by passing in the name of the script.

name type description
typeOrClassName Function | String

returns:

type: Component

examples:

// get sprite component.
var sprite = node.getComponent(cc.Sprite);
// get custom test calss.
var test = node.getComponent("Test");

getComponents
(
  • typeOrClassName
)
Component[]

Inherited from Component:

Returns all components of supplied Type in the node.

name type description
typeOrClassName Function | String

returns:

type: Component[]

examples:

var sprites = node.getComponents(cc.Sprite);
var tests = node.getComponents("Test");

getComponentInChildren
(
  • typeOrClassName
)
Component

Inherited from Component:

Returns the component of supplied type in any of its children using depth first search.

name type description
typeOrClassName Function | String

returns:

type: Component

examples:

var sprite = node.getComponentInChildren(cc.Sprite);
var Test = node.getComponentInChildren("Test");

getComponentsInChildren
(
  • typeOrClassName
)
Component[]

Inherited from Component:

Returns the components of supplied type in self or any of its children using depth first search.

name type description
typeOrClassName Function | String

returns:

type: Component[]

examples:

var sprites = node.getComponentsInChildren(cc.Sprite);
var tests = node.getComponentsInChildren("Test");

_getLocalBounds
(
  • out_rect
)

Inherited from Component:

If the component's bounding box is different from the node's, you can implement this method to supply a custom axis aligned bounding box (AABB), so the editor's scene view can perform hit test properly.

name type description
out_rect Rect

the Rect to receive the bounding box

onRestore ( )

Inherited from Component:

onRestore is called after the user clicks the Reset item in the Inspector's context menu or performs an undo operation on this component.

If the component contains the "internal state", short for "temporary member variables which not included
in its CCClass properties", then you may need to implement this function.

The editor will call the getset accessors of your component to record/restore the component's state
for undo/redo operation. However, in extreme cases, it may not works well. Then you should implement
this function to manually synchronize your component's "internal states" with its public properties.
Once you implement this function, all the getset accessors of your component will not be called when
the user performs an undo/redo operation. Which means that only the properties with default value
will be recorded or restored by editor.

Similarly, the editor may failed to reset your component correctly in extreme cases. Then if you need
to support the reset menu, you should manually synchronize your component's "internal states" with its
properties in this function. Once you implement this function, all the getset accessors of your component
will not be called during reset operation. Which means that only the properties with default value
will be reset by editor.

This function is only called in editor mode.

schedule
(
  • callback
  • [interval =0]
  • [repeat =cc.macro.REPEAT_FOREVER]
  • [delay =0]
)

Inherited from Component:

Schedules a custom selector.
If the selector is already scheduled, then the interval parameter will be updated without scheduling it again.

name type description
callback function

The callback function
interval optional Number 0

Tick interval in seconds. 0 means tick every frame. If interval = 0, it's recommended to use scheduleUpdate() instead.
repeat optional Number cc.macro.REPEAT_FOREVER

The selector will be executed (repeat + 1) times, you can use kCCRepeatForever for tick infinitely.
delay optional Number 0

The amount of time that the first tick will wait before execution.

examples:

var timeCallback = function (dt) {
  cc.log("time: " + dt);
}
this.schedule(timeCallback, 1);

scheduleOnce
(
  • callback
  • [delay =0]
)

Inherited from Component:

Schedules a callback function that runs only once, with a delay of 0 or larger.

name type description
callback function

A function wrapped as a selector
delay optional Number 0

The amount of time that the first tick will wait before execution.

examples:

var timeCallback = function (dt) {
  cc.log("time: " + dt);
}
this.scheduleOnce(timeCallback, 2);

unschedule
(
  • callback_fn
)

Inherited from Component:

Unschedules a custom callback function.

name type description
callback_fn function

A function wrapped as a selector

examples:

this.unschedule(_callback);

unscheduleAllCallbacks ( )

unschedule all scheduled callback functions: custom callback functions, and the 'update' callback function.
Actions are not affected by this method.

examples:

this.unscheduleAllCallbacks();

_destruct ( ) private

Clear all references in the instance.

NOTE: this method will not clear the getter or setter functions which defined in the instance of CCObject. You can override the _destruct method if you need, for example: _destruct: function () { for (var key in this) { if (this.hasOwnProperty(key)) { switch (typeof this[key]) { case 'string': this[key] = ''; break; case 'object': case 'function': this[key] = null; break; } } }

_onPreDestroy ( ) private

Called before the object being destroyed.

(
  • exporting
)
