You can override on_update.js.rjs to add some javascript code. Create
on_update.js.rjs in app/views/subjects/on_update.js.rjs, calling
render :super and adding your javascript to reload another subjects
page << render(:super)
@record.lecturer.subjects.each do |subject|
page << %|var row = $("#{element_row_id(:action => :list, :id =>
subject.id)}");
if (row) {
new Ajax.Updater(row, "#{}", {onComplete: function() {
if (row.hasClassName('even-record'))
$(row.id).addClassName('even-record');
}
});
}|
end
