JavaScript Support

Hello there -

I have a fairly complex simulation that I am building out with the Lectora V21 application. I am stumped at one spot though.

I have a variable called _Lane2SearchDetails that is instantiated by Lectora and I either add or subtract values based on button clicks. There is a finite amount of information that can be assigned to that _Lane2SearchDetails (z1,z2,z3,z4,z5,z6).

Since this variable essentially is an array separated by commas, I would like to split the array using the str.split(',') function built into JavaScript. My best attempt is in a screenshot below.



Now, when I call that function I always get a minimum of one object in the array length, and it only goes up from there or down as a button is unclicked - but it never goes to 0 if there is no objects in the string or ~~~~null~~~~.

The flow occurs as listed below.

Button 1 Clicked (Enabled): Array length = 2, Array contents = z1,
Button 2 Clicked (Enabled): Array length = 3, Array contents = z1,z2,
Button 3 Clicked (Enabled): Array length = 4, Array contents = z1,z2,z3
Button 1 Clicked (Disabled): Array length = 3, Array contents = z2,z3,
Button 2 Clicked (Disabled): Array length = 2, Array contents = z3,
Button 3 Clicked (Disabled): Array length = 1, Array contents = ~~~null~~~

Unsure why it is giving me the array length of current length + 1.

Anything I am doing wrong (obviously I am)?
