I am trying to access the value of inner function variable outside. But I cannot use it outside the inner function. My code is-
function t9(){
var start=298;
var diff;
function count(){
var end=400;
var diff=end-start;
}
return diff;
}
Dont re-declare the variable, so instead of : var diff=end-start;
write- diff=end-start;
Thats it
function t9()
var start=298;
return count(start);
}
function count(start){
var end=400;
var diff=end-start;
return diff;
}
function t9(){
var start=298;
var diff;
var end;
function count(){
end=400;
diff=end-start;
}
count();
alert(diff);
}
t9();
