Can't capture listbox selection in application builder

Hi everyone,

 

I'm new to jmp and I'm trying to use the application builder. I have a launch module with a listbox and two values, "ER" and "IL". Once a user presses a button, I'd like to be able to capture which selection(s) they chose, if any. 

For some reason, when I print "AnalysisSelected" to the text box, the text that appears is "List". It works if I choose to only print "AnalysisSelected[1]" to the text box, but I want to be able to loop through the selected analyses and take proper action once I pass the variable to the GraphBuilder...

 

Thanks in advance!!

 

Re: Can't capture listbox selection in application builder

You're close.  A few notes:

• list(AnalysisSelected) does not do anything but create {AnalysisSelected}.  
• Get Selected for a listbox returns a list
• If you're trying to put a number into a text box you need to convert it to a character with char().

Try this code:

analysis_list = analysistypes << get selected;
var = nitems(analysis_list);
if (var > 0,
 analysisselected = analysis_list[1]; // Assumes you're restricting # choices to 1
 ,
 error text << set text(char(var));
);

A list box is container for any kind of display boxes to display them in sequence vertically or horizontally.  Is AnalysisTypes a radio box?

JSL as far as I know does not use the "this"/"self"/"me" convention of object-oriented languages, so that part of your script is not doing anything.

 

If AnalysisTypes is a radio box and Error Text is a textbox, your function should look like this:

RunAnalysis = function({},
 AnalysisSelected = AnalysisTypes << Get Selected;
 //show(AnalysisSelected);
 Error Text << Set Text(AnalysisSelected);
);

The "show(AnalysisSelected)" line is commented out, but you can uncomment that line and see what the value of that variable is in the log.  That is a really handy function to use for debugging.

 

I attached a working example in App Builder using this script.

 

You said you are new to JMP, and I would recommend taking the time to learn the fundamentals of JSL before jumping right into App Builder.  That's a lot to try to chew for a new user.  Jump Into JMP Scripting by Wendy Murphrey and Rosemary Lucas is a fantastic book that I would highly recommend purchasing if you plan to use JSL a lot.  I wrote a gentle introduction to Application Builder a couple years ago that you may also find helpful: https://community.jmp.com/t5/Discussions/Gentle-Introduction-to-Application-Builder/m-p/49629#M28232
