| <CE | |
| VALUE=val | val is an optional value the UP.Phone stores to the variable specified by the KEY option (specified in the <CHOICE> statement that contains the <CE> statement) when the user chooses the item. |
| LABEL=key_label | The label for the ACCEPT key when the choice entry
is selected. key_label should be five characters or shorter.
When the choice entry is selected this label overrides any labels specified at the card or the deck level. |
| TASK=task_type | The task to execute. If you specify a task, it
takes precedence over any actions specified at the card or deck level.
Possible task_type values are: GO: requests the URL specified by the DEST option. GOSUB: requests the URL specified by the DEST option, spawning a nested activity. RETURN: returns from a nested activity to the previous activity. CANCEL: cancels the current nested activity, returning to the previous activity. PREV: displays the previous card in the activity history. If the current card is the first card, PREV has the same effect as CANCEL. CALL: places a phone call to the number specified by the number option. The options listed below (e.g. DEST, VARS) are valid only with certain task types. For more detailed descriptions of the task types and the options you can use with them, see Task types. |
| DEST=dest_url | The URL to request in GO and GOSUB
tasks.
If the current activity is nested and the task is a RETURN or CANCEL task, DEST specifies a URL to request upon returning to the calling activity. However, if the calling activity does not designate the current activity as "friendly," the UP.Phone ignores the DEST option. The DEST option overrides the NEXT or CANCEL options of the calling activity. |
| REL=NEXT | Instructs the phone to prefetch the URL specified
by the DEST option. The phone loads and caches the URL while the
user is viewing the current card.
If the user invokes the action (requesting the URL) the phone can retrieve the URL from the cache instead of requesting it from the UP.Link server. This gives the user a perception of enhanced performance. There is no guarantee that the phone will be able to prefetch the specified URL. For example, if the phone is on a circuit-switched network and the circuit is down, the phone will not open a circuit. If the phone fails to execute the prefetch, it does not retry it. If you specify the REL=NEXT option, the URL is added to the end of the phone's cache. If the user does not request the URL soon after the phone caches it, the phone pushes it out of the cache, and caches other data instead. If several tasks on a card specify the REL=NEXT option, the phone prefetches the URLs in the order in which the tasks are listed. |
| METHOD=get_or_post | If the DEST option specifies a URL, the method
used to request the URL: GET or POST.
If you do not specify this option, the default, GET, is used. It is strongly recommended that you use the POST method instead of the GET method. Using the POST method ensures that the UP.Link server will properly transcode data from the phone to the correct character set for your application (as specified by the HTTP headers set by your application). |
| POSTDATA=data | The data to post if the METHOD option specifies POST. If the data contains multiple arguments, delimit the arguments with ampersands (&). |
| ACCEPT-CHARSET=chset | Specifies the character set which the HDML application
expects data returned from the phone to use.
It can specify character set names, such as the following: utf-8
If you do not specify the ACCEPT-CHARSET option, the character set defaults to the character set of the deck (as specified by the deck's HTTP headers). |
| VARS=var_pairs | A list of variables to set for the current activity
(if the task is GO) or nested activity (if the task is GOSUB).
The variable list must be in query-string format, for example:
Variable values must be escaped according to URL escaping conventions. The phone unescapes the VARS option before setting the value of the variables. |
| RECEIVE=var_list | A semicolon-delimited list of variables to which
the phone stores the return values from a GOSUB task.
The phone stores return values according to ordinal position. For example, if you specify the following option: the phone stores the first return value to var1 and the second return values to var2. If you want to skip a return value, you must include a semicolon as a placeholder. For example, to ignore the first return value and store the second return value to var2, you specify the following option: |
| RETVALS=val_list | A semicolon-delimited list of values that an activity
invoked with GOSUB returns to the invoking activity. The RETVALS
option is allowed only with the RETURN task.
The values must be escaped according to URL escaping conventions. |
| NEXT=next_url | The URL to request after a nested activity returns.
If the FRIEND option in the GOSUB task is set to TRUE, the NEXT option can be overridden by the DEST option in the nested activity's RETURN task. |
| CANCEL=cancel_url | The URL to request after a nested activity invoked
by a GOSUB task cancels.
If the FRIEND option in the GOSUB task is set to TRUE, the CANCEL option can be overridden by the DEST option in the nested activity's CANCEL task. |
| FRIEND=boolean | A boolean value specifying whether the nested
activity specified in a GOSUB task is "friendly." A friendly nested
activity can use the DEST and CLEAR options in RETURN
and CANCEL tasks and override the NEXT and CANCEL
options of the calling task.
To indicate the nested activity is friendly, specify TRUE. The default is FALSE. |
| SENDREFERER=boolean | A boolean value specifying whether the UP.Browser
should provide the URL of the current deck when requesting the URL specified
by the DEST or NEXT options. If you set it to TRUE,
the UP.Browser specifies the deck's URL in the "Referer" header of the
request.
The UP.Browser attempts to use the shortest possible relative URL in the "Referer" header if possible. |
| CLEAR=boolean | A boolean value specifying whether a RETURN
or CANCEL task from a nested activity unsets all the calling
activity's variables. To unset the calling activity's variables, specify
TRUE. The default is FALSE.
The phone ignores the CLEAR option unless the calling activity specifies that the current activity is "friendly." |
| NUMBER=number | For a CALL task, the phone number to call. |
| > | |
| text | Formatted text describing the choice entry. You
can insert an image as a choice item by using an <IMG> statement
in this text (see Using images in choice entries
below).
By default, the UP.Phone always displays the text in horizontal scrolling (<LINE>) mode. To make it wrap, insert a <WRAP> statement before the text. If you did not specify ALPHA for the choice method, the item's number is automatically prepended to the text. |
