can u give me an example to use publication.nbSetVar in jscripts

Here is a demo javascript function that takes a number passed as the first parameter in a Call command, adds one to it, and stores the result as a VNWin variable ... and then displays this variable (using AlertBox) from within the javascript function.

// showcase to get, set and execute in javascript functions
function jsGetSetExec(a){
var b = a+1;
nbSetVar("[gk]",b);
nbExecAction('AlertBox "b=" "[gk]"');
}
jsGetSetExec([inputNumber]);

In the Function parameters section, please add ...

Alias: [inputNumber]
Type: Number
Description: number passed as input

You can name this function file whatever you desire; just use the same name as the first parameter in your Call command.

I think it is because javascript (unlike vbscript) does not support a count method ... there are a few examples on the internet that show how you can get a count of the number of key/value pairs in a JSON object ... if you can not find them (using Google search), just holler and I will post links.

@victor

Another example that also demos nbGetVar ...

a) attach this code to a button ...

SetVar "[gkStringIn1]" "abcd"
SetVar "[gkStringIn2]" "wxyz"

Call "jsDemo2"

AlertBox "gkStrinOut" "[gkStringOut]"

b) make this content of function file jsDemo2 ...

// showcase to getVar and setVar in javascript functions
jsInput1 = nbGetVar( "[gkStringIn1]" )
jsInput2 = nbGetVar( "[gkStringIn2]" )

jsOutput = jsInput1 + "..." + jsInput2;
nbSetVar("[gkStringOut]",jsOutput);
