Something like that, yes.

You now have

function init() {
    var vectorLayer = ...;
}

function test() {
    alert(typeof vectorLayer); // "undefined"
}

So vectorLayer is only known to the init method. Instead, you will want:

var vectorLayer;

function init() {
    vectorLayer = ...;
}

function test() {
    alert(typeof vectorLayer); // "Object"
}

Regards,
Andreas.
