jquery - Update Rails Variable in ERB using Ajax -


i have dropdown menu of patients. when user selects patient dropdown menu, want use jquery patient's id, make ajax call server return patient variable can use in view.

dropdown:

    <%= f.select :patient_id, content_tag(:option,'select  patient...',:value=>"")+content_tag(:option,'new  patient',:value=>"")+options_from_collection_for_select(@patients, 'id',  'full_name'), :class=>"form-control" %>

js:

 $('#assessment_patient_id').change(function(){ var e = document.getelementbyid("assessment_patient_id"); var patient_id = (e.options[e.selectedindex].value)  if (patient_id == 0) {   window.location.href = "/patients/new" } else {   $.ajax({     type: "post",     url: "get-patient",     data: {patient_id: patient_id},     success: function(data){       console.log(data)     },     error: function(err){       console.log(err);     }   });   }

controller:

respond_to :js, :html, :json        def get_patient         @patient = patient.find(params[:patient_id])        respond_with @patient      end

routes:

  'assessments/get-patient', :to => 'assessment#get_patient'

get-patient.js.erb

$('#assessment-type').slidedown(350);

what i'm trying accomplish ability go <%= @patient.method_name_here %> in view after user selects patient drop down.

but can't figure out how data object controller. go?

you this. in view add div id#patient-name (for example)

then, js.erb file can update dom.

# get-patient.js.erb  $('#assessment-type').slidedown(350); $('#patient-name').html('#{j(@patient.name)}');

and, request go patients_controller#show instead?
