How to pass the javascript value as json object to the controller in ruby on rails?

Question

I have got a task to do knockout.js using ruby on rails. I want to send the javascript value to the controller. My index.html.erb is

<%= javascript_inclu         


        

Answer 1

Just try this.

 $.ajax({
      url:'/employees/<%=@employee.id%>',
      dataType: 'json',
      data: { passval: dataToSave},
      success: function(msg) 
           { 

           }
       });

you can use the variable passval in the ajax page for retrieving the value of dataTosave,
and the variable msg will return the response from the ajax.
