Create one or more page timers that shows elapsed time when the timer is called.

The timer shows the elapsed time in milliseconds since it was created, or since it was reset.

As default the timer is returned as a formatted string, but it can also be returned as an integer value or as a decimal seconds value.

Works with Lasso 6 and later (maybe also Lasso 5).

Parameters

none

Sample Usage

// create a timer instance
var: 't'=js_timer;

// simulate a lengthy code run
sleep: 1234;

// output the timer as string formatted as "1 234 ms"
$t;

// simulate some more code
sleep: 200;

// output the timer as seconds (decimal value)
$t -> seconds;

// reset the timer
$t -> reset;

// simulate some more code
sleep: 321;

// output the timer as an integer value
$t -> integer;
