how to call variable value from one function to other function

[divya123]

Below script from executeSample function i need to take date2  variable value and pass it to addSchedule2 function , please help me your suggestions.

gs.include('DurationCalculator');
executeSample();
function executeSample(){
var dc = new DurationCalculator();
addSchedule(dc);
var created = '22-Nov-2019 11:25:31';
var gdt = new GlideDateTime(created);
dc.setStartDateTime(gdt);
if(!dc.calcDuration(2*8*3600)){ // 2 days
gs.log("*** Error calculating duration");
return;
}
gs.log("calcDuration no schedule: " + dc.getEndDateTime());
var date2 = dc.getEndDateTime();
gs.print(dc.getEndDateTime());
}

function addSchedule(durationCalculator){
// Load the "8-5 weekdays excluding holidays" schedule into our duration calculator.
var scheduleName = "8-5 weekdays";
var grSched = new GlideRecord('cmn_schedule');
grSched.addQuery('name', scheduleName);
grSched.query();
if(!grSched.next()){
gs.log('*** Could not find schedule "'+ scheduleName +'"');
return;
}
durationCalculator.setSchedule(grSched.getUniqueValue(),"IST");
}

gs.include('DurationCalculator');
executeSample2();
function executeSample2(){

var dc = new DurationCalculator();
addSchedule2(dc);
var created = date2;
var gdt = new GlideDateTime(created);
dc.setStartDateTime(gdt);
if(!dc.calcDuration(2*8*3600)){ // 2 days
gs.log("*** Error calculating duration");
return;
}
gs.log("calcDuration no schedule: " + dc.getEndDateTime());
var date3 = dc.getEndDateTime();
gs.print(dc.getEndDateTime());
}

function addSchedule2(durationCalculator){
// Load the "8-5 weekdays excluding holidays" schedule into our duration calculator.
var scheduleName = "8-5 weekdays";
var grSched = new GlideRecord('cmn_schedule');
grSched.addQuery('name', scheduleName);
grSched.query();
if(!grSched.next()){
gs.log('*** Could not find schedule "'+ scheduleName +'"');
return;
}
durationCalculator.setSchedule(grSched.getUniqueValue(),"IST");
}

You can use the function to set the value of a variable outside the context of the function, then you can use it as an argument in another function.

gs.include('DurationCalculator');
var date2 = executeSample();  //set the variable value by calling the function

function executeSample(){
var dc = new DurationCalculator();
addSchedule(dc);
var created = '22-Nov-2019 11:25:31';
var gdt = new GlideDateTime(created);
dc.setStartDateTime(gdt);
if(!dc.calcDuration(2*8*3600)){ // 2 days
gs.log("*** Error calculating duration");
return;
}
gs.log("calcDuration no schedule: " + dc.getEndDateTime());
return = dc.getEndDateTime();
gs.print(dc.getEndDateTime());
}

function addSchedule(durationCalculator){
// Load the "8-5 weekdays excluding holidays" schedule into our duration calculator.
var scheduleName = "8-5 weekdays";
var grSched = new GlideRecord('cmn_schedule');
grSched.addQuery('name', scheduleName);
grSched.query();
if(!grSched.next()){
gs.log('*** Could not find schedule "'+ scheduleName +'"');
return;
}
durationCalculator.setSchedule(grSched.getUniqueValue(),"IST");
}

gs.include('DurationCalculator');
executeSample2(date2);  //send the variable in as a parameter to the function

function executeSample2(date){  //add the variable as an argument
var dc = new DurationCalculator();
addSchedule2(dc);
var created = date;
var gdt = new GlideDateTime(created);
dc.setStartDateTime(gdt);
if(!dc.calcDuration(2*8*3600)){ // 2 days
gs.log("*** Error calculating duration");
return;
}
gs.log("calcDuration no schedule: " + dc.getEndDateTime());
var date3 = dc.getEndDateTime();
gs.print(dc.getEndDateTime());
}

function addSchedule2(durationCalculator){
// Load the "8-5 weekdays excluding holidays" schedule into our duration calculator.
var scheduleName = "8-5 weekdays";
var grSched = new GlideRecord('cmn_schedule');
grSched.addQuery('name', scheduleName);
grSched.query();
if(!grSched.next()){
gs.log('*** Could not find schedule "'+ scheduleName +'"');
return;
}
durationCalculator.setSchedule(grSched.getUniqueValue(),"IST");
}

Hi David, 

thank you for your quick response, if i execute background script for this  date2 and date3 both are coming same value , it should not come same value,  based on date2 value date3 value has to change rgt 

[Dubz]

If you're in background scripts you might have to wrap the whole thing up in a function eg:

runFunctions()
function runFunctions(){
var date2 = executeSample();
executeSample2(date2);
}

function executeSample(){
//code
}
etc etc

I haven't tested the code, it's just a method you can use. To have a variable from one function context available in another you can either populate a variable in the global context or call the other function from within the first and pass through the variable as an argument eg:

function executeSample(){
var dc = new DurationCalculator();
addSchedule(dc);
var created = '22-Nov-2019 11:25:31';
var gdt = new GlideDateTime(created);
dc.setStartDateTime(gdt);
if(!dc.calcDuration(2*8*3600)){ // 2 days
gs.log("*** Error calculating duration");
return;
}
gs.log("calcDuration no schedule: " + dc.getEndDateTime());
var date2 = dc.getEndDateTime();
executeSample2(date2);
gs.print(dc.getEndDateTime());
}

thank you David once again it is working as expected.
