Stop / reset JavaScript in a storyline
Hello, I have a timer that I built from a Storyline provided in another post; it uses a javascript snippet to start the timer and works great however, I am trying to add a feature to stop the timer...
Hi Math
Thanks for your reply and link to article about scope and adding JS functions to package.
If I understand the issue with the timer correctly - you can only access the function that operates the timer in the same slide and same trigger that initialize it.
So - as you say to use SL variables which have global scope, can you not have a variable called "pause" which fires on any slide you want if triggered, and a reference to that variable in the JS function that started the timer? So that whenever the pause variable is set to true - the JS timer will pause (provided of course the function is correctly coded to stop counting when pause = true)
Ditto for reset
Hi Sam,
Yeah basically thats correct. The difficulty in working with Storyline variables and scope for a timer is that with only one variable for pause it won't work. Say you initialize your timer on the first slide, lets call it slide A with trigger tA... the scope for that timer is then exactly there. You can tell the global variable ( varT = true ) the timer is running...and thus..when you get to slide B you do know the timer is running... and you can change the global variable ( varT = off )...but you then donot have access to the scope of the timer...because that is on slide A with trigger tA.
So when using variables only you need to add the timer itself to a global variable, so you access it anywhere. In fact that is cumbersome because in the end it takes quite a few variables for it to work. I prefer a global script on root level... i will make a sample when time permits this week.
