Select_taf上的Ajax和JS；SyntaxError:属性列表后缺少}

Question

我的Js和AJAX代码有什么问题？我在select_tag上使用ajax和JS，并在ajax中得到错误；

- @departments = @collocation_request.collocation_request_departments

 td Reviewer
      - @departments.each do |department|
           td
              div.input-append
                = select_tag :reviewer_id, options_from_collection_for_select(User.where(department_id:                   department.department_id), "id","full_name"), prompt: 'Select a Reviewer', remote: true

    javascript:
          $(function(){
            $(document).on('change','#reviewer_id',function(e) {
                alert($(this).val());
                var collocation_request_id = $(this).data('collocation-request-id');
                var departments_id = $(this).data('department-id');
                jQuery.ajax({
                  type: "PUT",
                  dataType: 'JSON',
                  data: {collocation_request_department: {reviewer: $(this).val()},
                  url: '/collocation_requests/'+collocation_request_id+'/departments/'+departments_id+'.js'
                }).complete(function(data, textStatus, jqXHR) {
                window.location = window.location;
                });
              });
          });

Answer 1

在数据中添加}

data: {collocation_request_department: {reviewer: $(this).val()}},
