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.

• cdoshi: Define setData outside the click callback block
• noushad mohammed: var value=setData(); function addSubjectTeacher(){console.log(value)}
• Patrick Roberts: 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.

Answer 1

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);
}
