Hello LF community,

Is it possible to make a field read-only after it is submitted? I know the general way is to create a copy of the form and make those fields read-only via the layout designer. However, I cannot use that method as I am sending the same form to external users and populating the read-only fields by URL parameters. 

The current javascript code I am using is:

$(document).ready(function () {
   $('.ro input').prop('readonly',true);
   $('.ro select').prop('readonly',true);
});

However, this doesn't seem to work for me.

Thank you,

Daniel
