The object Element - <object>
Description:
A VoiceXML implementation platform may have platform-specific functionality that an
application wants to use, such as speaker verification, native components, additional telephony
functionality, and so on. Such platform-specific objects are accessed using the <object>
element, which is analogous to the HTML <OBJECT> element.
Example:
<object name="debit"
classid="method://credit_card/gather_and_debit"
data="http://www.recordings.example/prompts/credit/jesse.jar"/>
<param name="amount" expr="document.amt"/>
<param name="vendor" expr="vendor_num"/>
</object>
| Attributes |
| Name |
Value |
Description |
| name |
PCDATA |
When the object is evaluated, it sets this variable to an ECMAScript
value whose type is defined by the object. |
| expr |
PCDATA |
The initial value of the form item variable; default is ECMAScript
undefined. If initialized to a value, then the form item will not be
visited unless the form item variable is cleared. |
| cond |
boolean |
A boolean condition that must also evaluate to true in order for the form item to be visited. |
| classid |
URI |
The URI specifying the location of the object’s implementation. The
URI conventions are platform-dependent. |
| codebase |
PCDATA |
The base path used to resolve relative URIs specified by classid,
data, and archive. It defaults to the base URI of the current
document. |
| codetype |
PCDATA |
The content type of data expected when downloading the object
specified by classid. When absent it defaults to the value of the
type attribute. |
| data |
URI |
The URI specifying the location of the object’s data. If it is a relative
URI, it is interpreted relative to the codebase attribute. |
| type |
PCDATA |
The content type of the data specified by the data attribute. |
| archive |
URI |
A space-separated list of URIs for archives containing resources
relevant to the object, which may include the resources specified by
the classid and data attributes. URIs which are relative are
interpreted relative to the codebase attribute. |
| caching |
'safe' or 'fast' |
Eithere safe to force a query to fetch the most recent copy of the content, or fast to use the cached copy of the content if it has not expired. If not specified, a value derived from the innermost caching property is used. |
| fetchaudio |
URI |
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. |
| fetchint |
"prefetch", "safe", "stream" |
Defines when the interpreter context should retreive 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. In the case of a very large file (implying long download times) or a streaming audio source, stream indicates to the interpreter context to begin processing the content as it arrives and should not wait for full retrieval of the content. If not specified, a value derived from the innermost relevant *fetchint property is used. |
| fetchtimeout |
integer |
The interval to wait for the content to be returned before throwing an error.badfetch event. If not specified, a value derived from the innermost fetchtimeout is used. |
