jquery - How to change the value of variable in a function in javascript? -
var e = 15; function change_value(e){ e = 10; } change_value(e); console.log(e);
the value of e still 15.
the e
inside function scope different e
inside global scope.
just remove function parameter:
var e = 15; function change_value(){ e = 10; } change_value(); console.log(e);
