Sort numbered variables
I have 8 number variables, all that are added to depending on what the learner picks throughout a quiz. These variables will then suggest the top three courses to do. Is there a way to sort the numbe...
// Get the values of the 8 variables and put them in an array
var variables = [ player.GetVar("Variable1"),
player.GetVar("Variable2"),
player.GetVar("Variable3"),
player.GetVar("Variable4"),
player.GetVar("Variable5"),
player.GetVar("Variable6"),
player.GetVar("Variable7"),
player.GetVar("Variable8") ];
// Sort the array in descending order and get the top three values
var topThree = variables.sort((a, b) => b - a).slice(0, 3);
// Set the top three values back to Articulate variables if needed
player.SetVar("Top1", topThree[0]);
player.SetVar("Top2", topThree[1]);
player.SetVar("Top3", topThree[2]);
JS Script could be your helping hand.
Thank you, I was thinking JS may be the answer but I don't know much about it so I will give this a go and see what happens. Thank you
Is the "Top1", "Top2", "Top3" the variables to report back into articulate to use to show the answers?
Yes. You create those variables in Articulate to host the result before you run the script. This script will assign them values when it is done running.
Thank you for this. I am really not familiar with JS so not sure how it works. I have done all you have suggested, but its not populating the Top1, Top2 and Top3 variables. I am getting values NaN in Top2 and Top3. Really appreciate your help but I dont think I have the knowledge to try and use JS.
