I have a form that needs to be displayed after an individual has logged in. The form itself contains only one field to upload an image. I want to be able to associate this image to the particular user who uploaded it. This name field should be fixed and equal to the user name entered by the user when they logged in. Let's say it is denoted by a div with id = "userName". I want to use jquery or javascript selector to get this "userName" field and fill this value into the form, or attach it to the data before sending it to drive. Is that doable?
