How to get the value of a property in an extension from a function to the main code?

[warfollowmy_ver]

var MyObj = {MyVar:0};

var CurrentDocument = Qv.GetCurrentDocument();

CurrentDocument.GetAllVariables(function (vars) {
    for (var i = 0; i < vars.length; i++) {
         if (vars[i].name === "MyVariable") {
              MyObj .MyVar= vars[i].value;
         break;
         };
    };

    alert(MyObj .MyVar); //Work

};

   alert(MyObj .MyVar); //Undifined

Option with definition  below do not offer.  Firstly, it does not work in document extension. Secondly, when changing the xml, you need to delete and recreate the extension in the document each time. It came up with an idiot.

Definition.xml:

<Text Label="Text0" Type="text" Expression="=MyVariable"/>

P.S. This forum thread consists of corpses and no one can answer the sipmle questions that are asked?
