noinput

noinput element

Executes when the user does not speak within the active field.

Syntax

<noinput 
cond = "ECMAScript_Expression"
count = "integer"
/>

Attributes

cond	A condition that must evaluate to true for this element to be selected by the form interpretation algorithm.
count	Used by the VoiceXML interpreter in the event handler selection process, allowing the developer to handle multiple occurrences of the noinput event in a unique manner. The default value is 1.

Parents

field, form, initial, menu, object, record, subdialog, transfer, vxml

Children

assign, audio, break, clear, data, disconnect, enumerate, exit, foreach, goto, if, log element, mark, prompt, reprompt, return, script, submit, throw, value, var

Remarks

The noinput event handler catches the noinput event. The Platform throws a noinput event if it doesn't hear spoken or DTMF input within the designated timeout interval.

The noinput element is shorthand for a catch element with its event attribute set to "noinput."

Examples

The following example includes three noinput handlers. The first two handlers play a message and give the user another opportunity to supply input; the third terminates the application.
