jSignage.setTimeout()

Executes one time the callback function after the duration specified by ms. Returns a handler to the timer in case it needs to be canceled before the execution.

$.setTimeout( callback, ms );

Returns: Timer Object

Parameters:

  • callback
    Type: Callback.
    The function to be executed after the duration specified by ms.
  • ms
    Type: Number. Default: 0.
    The number of milliseconds (thousandths of a second) that the callback function call should be delayed by.

jSignage.clearTimeout()

Cancels a timer created with the setTimeout function.

$.clearTimeout( timer );

Returns: Undefined

Parameters:

jSignage.setInterval()

Executes repeatedly the callback function with a fixed time delay between each call. Returns a handle to the timer in case it needs to be canceled.

$.setInterval( callback, ms );

Returns: Timer Object

Parameters:

  • callback
    Type: Callback.
    The function to be executed repeatedly.
  • ms
    Type: Number.
    A positive number of milliseconds (thousandths of a second) to wait between calls to the callback function.

jSignage.setIntervalSync()

Added in firmware 3.0.6 release.

Executes repeatedly the callback function with a fixed time delay between each call, just like setInterval function, except that the first call is done after a delay that is most probably shorter that the one provided as parameter, in order to synchronize together multiple timers having the same delay. Returns a handle to the timer in case it needs to be canceled.

$.setIntervalSync( callback, ms );

Returns: Timer Object

Parameters:

  • callback
    Type: Callback.
    The function to be executed repeatedly.
  • ms
    Type: Number.
    A positive number of milliseconds (thousandths of a second) to wait between calls to the callback function.
