Make Dynamics CRM 2011 field readonly NOT disabled

I would like to make a inputfield readonly. I am familiar with the
setDisabled() method in XRM, the downside of this method is that it is not
possible to copy/paste values from the fields.
Is there another way then using javascript/jQuery directly to set the
readonly property on the field by using it's field name?
Kind regards Rim
