How to get the value of a variable in a variable JS?

[warfollowmy_ver]

I do not understand how to retrieve the value of a variable in a global variable JS.

Help me please.

Qv.AddExtension('Test', function () {

    var var1;

    var doc = Qv.GetCurrentDocument();

    doc.GetAllVariables(function (vars) {

            for (var i = 0; i < vars.length; i++) {

                if (vars.name === "var1") {

                    var1 = vars.value;

                 break;

              };

       }      

    });

    alert(var1); \\undefined

});

It looks like doc.GetAllVariables is an async function. That means, that your alert(var1) is executed before doc.GetAllVariables() has finished. You need to wait for that function to be finished. Please take a look at Javascript Promises.
