Call variable in function

Is there any way to make variable that declare inside function can be call out side function ?

 

You can return the value of a variable from your function call

function hello()
{
var myname;
myname = "Jack";
return "hello I'm " + myname;
}

OR you could declare a global var


var myname = "Jack";

function hello()
{
return "hello I'm " + myname;
}

 

how about if i want return multiple value ?
