Javascript to duplicate every field

Question

Is there a way to duplicate every instance of a field in a document?
I have a document with multiple fields (e.g. 'QTY.12345', 'QTY.12346', etc.) that occur in several places in the same document. Since I had no luck finding a way to set a field format to a non-javascript number format, I am trying to set up a script to duplicate every field wherever it exists in the document (the 'QTY.12345' field might exist on several pages, or more than once on the same page) and give the duplicated field the more advanced javascript functions.
I can use the following to get every field in the 'QTY' family:
var f = this.getField("QTY");
var a = f.getArray();
var v = 0.0;
for (j =0; j < a.length; j++) {
var fieldName = a[j].name
app.alert ("Master field: " + fieldName)
...but I don't know how to find where each copy of the field exists in the document.
My goal is to have a document which will give the user limited functionality if they have Javascript disabled, but will reveal the javascript enabled fields (and hide the non-js fields) and activate any javascript features on startup. When the file is closed, it will restore the document to the original non-javascript state.

Hi,
According to your description, there are three hidden fields in the NewForm page, users select a value in the “Customer” field. Before submit, you want to send a request
to query the corresponding values for the three hidden fields, then perform the submit.
Per my understanding, the logic of the code can be like this: hide the three fields after page loaded, in the PreSaveAction() function, use Client Object Model with
CAML query to retrieve the item needed, set value to the three hidden fields, then submit.
From your code, we can see that you are able to get/set value of fields in the NewForm page, retrieve item and extract the values needed in the query success callback
function. Yes, you are in the right way.
As you have accomplished all the main steps of this solution, in my opinion, the rest work would be to make them work smoothly together in your page for better user
experience.
Feel free to reply if there any question during the process.
Best regards,
