I would consider using a class for both the css and the js, so as to not affect every .nx-fieldtext a on the page, unless that is the intent. You can add a classname, for instance, nolink to a field editor, a table, a wrapper etc. and any .nx-fieldtext a contained within will be affected:
skuid.$(‘.nolink .nx-fieldtext a’).click(function(e){e.preventDefault()});
and
.nolink .nx-fieldtext a, .nolink .nx-fieldtext a:hover{ color:inherit !important;
text-decoration:none !important;
cursor: text !important;
}
