PDFTron WebViewer Class: Action

Class: Action

Core .PDFNet. Action

new Action()

Actions are typically what happens when a user clicks on a link or bookmark. Instead of simply jumping to a destination in the document, an annotation or outline item can specify an action for the viewer application to perform, such as launching an application, playing a sound, or changing an annotation's appearance state. Note: Although the Action class provides utility functions for most commonly used action types, it is possible to read, write, and edit any action type using SDF API and dictionary entries described in Section 8.5 in the PDF Reference Manual.

Methods

<static> create( [in_obj])

A constructor. Creates an Action and initializes it using given Cos/SDF object.

Parameters:

Name	Type	Argument	Description
`in_obj`	Core.PDFNet.Obj	<optional>	Pointer to the Cos/SDF object. Note: The constructor does not copy any data, but is instead the logical equivalent of a type cast.

Returns:

A promise that resolves to an object of type: "PDFNet.Action"

Type: Promise.<Core.PDFNet.Action>

<static> createGoto(dest)

creates a new 'GoTo'action. GoTo action takes the user to the specified Destination view located in the same document.

Parameters:

Name	Type	Description
`dest`	Core.PDFNet.Destination	A Destination for the new Action. Note: This method can only be used for destinations in the same document as the source document. For cross-document links use Action::CreateGotoRemote().

Returns:

A promise that resolves to an object of type: "PDFNet.Action"

Type: Promise.<Core.PDFNet.Action>

<static> createGotoRemote(file, page_num)

creates a new 'GoToR'action. A remote go-to action is similar to an ordinary go-to action but jumps to a destination in another PDF file instead of the current file.

Parameters:

Name	Type	Description
`file`	Core.PDFNet.FileSpec	The file referred to by the action.
`page_num`	number	A page number within the remote document. The first page is numbered 0.

`page_num`	number	A page number within the remote document. The first page is numbered 0.
`new_window`	boolean	A flag specifying whether to open the destination document in a new window. If new_window is false, the destination document replaces the current document in the same window, otherwise the viewer application should behave in accordance with the current user preference.

Returns:

A promise that resolves to an object of type: "PDFNet.Action"

Type: Promise.<Core.PDFNet.Action>

Name Type Description

Name	Type	Description
`flag`	number	PDFNet.Action.FormActionFlag = { e_exclude : 0 e_include_no_value_fields : 1 e_export_format : 2 e_get_method : 3 e_submit_coordinates : 4 e_xfdf : 5 e_include_append_saves : 6 e_include_annotations : 7 e_submit_pdf : 8 e_canonical_format : 9 e_excl_non_user_annots : 10 e_excl_F_key : 11 e_embed_form : 13 } Action flag to get the value from.

PDFNet.Action.FormActionFlag = {
	e_exclude : 0
	e_include_no_value_fields : 1
	e_export_format : 2
	e_get_method : 3

	e_excl_F_key : 11
	e_embed_form : 13
}

Action flag to get the value from.

Returns:

A promise that resolves to boolean value of the given action flag. Note: Action flags are currently only used by submit and reset form actions.

Type: Promise.<boolean>

getNext()

Returns:

A promise that resolves to the next action dictionary, an array of action dictionaries, or NULL if there are no additional actions. Sequences of actions can be chained together. For example, the effect of clicking a link annotation with the mouse might be to play a sound, jump to a new page, and start up a movie. Note that the Next entry is not restricted to a single action but may contain an array of actions, each of which in turn may have a Next entry of its own. The actions may thus form a tree instead of a simple linked list. Actions within each Next array are executed in order, each followed in turn by any actions specified in its Next entry, and so on recursively.

Type: Promise.<Core.PDFNet.Obj>

getSDFObj()

Returns:

A promise that resolves to pointer to the underlying SDF/Cos object.

Type: Promise.<Core.PDFNet.Obj>
