Trying to return a variable outside of a function

I am pretty sure I am doing this wrong but what I want to happen is onload i want function test to run then function one then function two, and then I want function two to return var abc from function one.

window.onload=function(){
  test();
};

function test(){
    var abc;
  function one(){
    abc = 1;
    two();
  }
  function two(){
    console.log(abc);
  }

}

i want function test to run then function one

That's the step you were missing. Your test function currently only declares function one, but never calls it.

function test() {
    var abc;
    function one() {
        abc = 1;
        two();
    }
    function two() {
        console.log(abc);
    }
    one(); // call it!
}
test(); // logs 1

There might be better ways to share values between functions than closure (depending on the use case), but this does what you want.

You have only declared function one you need to executed it. At the end of the test function add one(); see below:

window.onload=function(){
    test();
};

function test(){
    var abc;
    function one(){
        abc = 1;
        two();
    }
    function two(){
        console.log(abc);
    }
    one();//execute function 1
}
