public final class Goto
extends AbstractXmlNode

Go to another dialog in the same or different document.

The <goto> element is used to:

• transition to another form item in the current form,
• transition to another dialog in the current document, or
• transition to another document.

To transition to another form item, use the nextitem attribute, or the expritem attribute if the form item name is computed using an ECMAScript expression:

<goto nextitem="ssn_confirm"/>
<goto expritem="(type==12)? 'ssn_confirm' : 'reject'"/>

To go to another dialog in the same document, use next (or expr) with only a URI fragment:

<goto next="#another_dialog"/>
<goto expr="'#' + 'another_dialog'"/>

To transition to another document, use next (or expr) with a URI:

<goto next="http://flight.example.com/reserve_seat"/>
<goto next="./special_lunch#wants_vegan"/>

The URI may be absolute or relative to the current document. You may specify the starting dialog in the next document using a fragment that corresponds to the value of the id attribute of a dialog. If no fragment is specified, the first dialog in that document is chosen.

Constant Field Values

ATTRIBUTE_NEXT

public static final String ATTRIBUTE_NEXT

The URI to which to transition.

See Also:

Constant Field Values

ATTRIBUTE_EXPR

public static final String ATTRIBUTE_EXPR

An ECMAScript expression that yields the URI.

Constant Field Values

ATTRIBUTE_EXPRITEM

public static final String ATTRIBUTE_EXPRITEM

An ECMAScript expression that yields the name of the next form item to visit.

See Also:

Constant Field Values

ATTRIBUTE_FETCHAUDIO

public static final String ATTRIBUTE_FETCHAUDIO

The URI of the audio clip to play while the fetch is being done. If not specified, the fetchaudio property is used, and if that property is not set, no audio is played during the fetch. The fetching of the audio clip is governed by the audiofetchhint, audiomaxage, audiomaxstale, and fetchtimeout properties in effect at the time of the fetch. The playing of the audio clip is governed by the fetchaudiodelay, and fetchaudiominimum properties in effect at the time of the fetch.

See Also:

Constant Field Values

ATTRIBUTE_FETCHTIMEOUT

public static final String ATTRIBUTE_FETCHTIMEOUT

The interval to wait for the content to be returned before throwing an error.badfetch event. This defaults to the fetchtimeout property.

See Also:

Constant Field Values

ATTRIBUTE_FETCHHINT

public static final String ATTRIBUTE_FETCHHINT

Defines when the interpreter context should retrieve content from the server. prefetch indicates a file may be downloaded when the page is loaded, whereas safe indicates a file that should only be downloaded when actually needed. This defaults to the audiofetchhint property.

See Also:

Constant Field Values

ATTRIBUTE_MAXAGE

public static final String ATTRIBUTE_MAXAGE

Indicates that the document is willing to use content whose age is no greater than the specified time in seconds. The document is not willing to use stale content, unless maxstale is also provided. This defaults to the audiomaxage property.

See Also:

Constant Field Values

ATTRIBUTE_MAXSTALE

public static final String ATTRIBUTE_MAXSTALE

Indicates that the document is willing to use content that has exceeded its expiration time. If maxstale is assigned a value, then the document is willing to accept content that has exceeded its expiration time by no more than the specified number of seconds. This defaults to the audiomaxstale property.
