Timing how long an interaction takes.

And here ..... is the storyline file!

gOOd LucK!

Many thanks, Berno! Good job. Another problem--how could I go about achieving remaining time by using JS in this case as Sam did to add it to each slide?  Sorry to trouble you !

Hi All,

I'm venturing - no really I'm tip-toeing - into Execution of JavaScript. And since I no NOTHING about it, I'm simply using what y'all offer here and C/P into the JavaScript box.So, I really appreciate the Q/A.

I know enough to understand that the trigger names must match the characters inside the Javascript window, e.g., in the case of the gsStart trigger, it matches the characters inside the first set of quotation marks in the player.SetVar line:

player.SetVar("gsStart", d.getTime());

So, I successfully implemented a trigger that shows how much time was spent on a previous slide when the Learner clicks the next button - and to display the time on the next slide. Essentially, I copied what you did, Berno, but using the next button instead of Submit.

What I really want to do is to have a counter that displays a number of seconds count on the current slide. So, nothing would be clicked, it would just count up in seconds. And I'd reference the count inside a text box.

I'd searched the forums a while back for this but didn't find exactly what I was looking for. Perhaps I missed it. Does anyone know how to do this?

And thanks again.

Hi, Rebecca - 

You'd need to do this with an interval to repeatedly update the second value. I'll test one out to make sure there's no funny business or side effects and post in a bit.

In the mean time, here are some DYNAMITE references for learning more about JavaScript. The codacademy site is instructional candy. So good. All practice and feedback. Appendto isn't bad either, more demonstration if that's your preference.

Probably a typeo, but gsStart is a Storyline variable, not a trigger.  If there is a way to fire a trigger in Storyline, it would be by setting a value in a variable to which a trigger is set to fire on that value.

Steve's suggestion of an interval timer is the right idea.  I look forward to seeing it implemented.

Sam, yep was a typo. And I DO understand the difference between triggers and variables ... really Tx for proofing/editing. Don't want to lead people down the wrong path, nor do I want them to think I don't know my whatchamacallit from my elbow.

Steve, tx so much. As I mentioned in another thread to Nancy, I'll need to add this to my ToDo list. In the meantime, looking forward to your post. Oh, there's no rush. Just something I had in mind. And I know you're busy.

Here's a quick and dirty example. I'm using a text variable to catch the value but you could just as easily use a number for logic inside of Storyline. Some cool concepts at work here. Noteable are the establishment of global functions that make it easier to start and stop the timer. It also continues to run between slides if you don't stop it.

The value in the setInterval call "1000" is milliseconds. So that's a 1 second tick.

Thanks a lot, Steve, It's wonderful !

Steve,

The global functions idea is great.

I've placed my Javascript in a seperate .js file.

It allows you to experiment / test the JS code after publishing. Just alter the code and refresh your browser.

Saves a lot of time compared to publishing after every code change.

And you could edit the code in a JS savvy editor.

You have to alter your story.html file and perform some post-publish copy actions

in the story.html find the place where other JS code is included:

and add your own:

After each publish copy the altered story.html over the newly published one and copy your .js file to the story_content folder.

Have a nice weekend!
