Just out of curiosity, can this “exec script” be recreated using puzzle blocks?

I created my first configurator for a client. It’s amazing how easy this is with Verge3D.
However, I have an “exec script” with the following javascript:

var newText = “”;
var elements = parent.document.querySelectorAll(“.cond87”);

for (var i = 0; i < elements.length; i++) {
elements.textContent = newText;
}

Just out of curiosity, can this be recreated using puzzle blocks?
