I tried 2 ways (code below), but I dont know how to get final value

In this case; "Activo"

        //way1
        var way1 = document.getElementById("Patrimonio");
        console.log(way1);
        //way2
        var way2 = document.getElementsByClassName("dx-placeholder");
        console.log(way2);

I expect obtain that value, to store in a javascript variable.
