Basically I have extra textboxes to use when uploading documents to set the keywords for that uploaded file.  

 

My question is when I select the downloaded file (left side of the insert document dialog) I see that the url dynamically changes and I would like it so my keywords change depending on which one is selected.   (something like this in short textbox.text = select keywords from tablename where fileID = @fileId)

 

I figured I would find the code that changes the url in insertDocument.js but the format is very hard to read, anyone know where I could do this? Even have it so that as a list item is select an alert box pops up, I could do the rest fine.\

 

Thanks
