Affect to a "label" the value of the selected item of a combobox in ruby on rails: How to make the label receive...

As per my understanding on changing or on selecting you have to set label on UI. To achieve this you have to use javascript, set id for select tag suppose id is country and set some label id suppose 'country_label' $("#country").change(function(){ var optionText = $("#country option:selected").text(); $("#country_label").text(optionText) // or val(optionText) check what is appropriate }); Or you have already selected combo box prior then you already know what is the value of city name you can directly add to <%=f.label :city,elected city name %>
