Declaring two variable with the same name

Question

Is it possible to call the same name variables which set outside of the function?

var a = $(window).width(); // I want to call this variable
if(!$.isFunction(p)){
    var a = $(window).height(); // Not this one
    alert(a);
}

Answer 1

In this case, you have actually redefined the value of a. There is absolutely no way of referencing a different variable with the same name, as it just acts as a redefinition.
