How to call a nested function from another function in javascript?

Question

I want to call a inner function from another function.I have code like

$(document).on('click','.td-subject-button',function(){ 
 var current= $(this).parent('td');     
     function setData(){
        return current;
     }
});

function  addSubjectTeacher(){
    var value=setData();
    console.log(value);
}

In the console i am getting the result as 'setData is not defined'. because the setData function is a nested function of a another function. so, how can i invoke setData function.

var value=setData(); function addSubjectTeacher(){console.log(value)} — noushad mohammed

This smells like an XY problem. Please explain what your actual problem is and don't get too attached to this attempted solution of calling a scoped function from the global scope. — Patrick Roberts

You can just define your var current outside [globally] and get its value as below.

Assumption - You will be calling addSubjectTeacher function after click event of td-subject-button

var current = "";
$(document).on('click','.td-subject-button',function(){ 
   current= $(this).parent('td');     
});

function  addSubjectTeacher(){
   var value=current;
   console.log(value);
}
