initialtimeout Attribute
.jpg) |
Specifies, in milliseconds, the initial time-out period for receiving the first dual tone multi-frequency (DTMF) press. Optional.
| HTML | <dtmf initialtimeout="timePeriod"> |
| JScript | dtmf.initialtimeout = timeperiod |
Remarks
If valid DTMF input is not received within the time period specified by the initialtimeout attribute, an onsilence event is raised and the status property is set to -11.
The range of values allowed for the initialtimeout attribute is from 1 to 60000, inclusive. An initialtimeout value of 0 disables the time-out. If initialtimeout is not specified, the default value of 5000 milliseconds, or 5 seconds, is used. If the programmer attempts to enter a value that is outside the acceptable range, the nearest in-range value is used.
Example
The following code demonstrates the use of the initialtimeout attribute.
