有没有办法在javascript中模拟content_for？

Question

我正在使用rails的content_for标签，但我想知道是否有办法模拟这个：

- content_for (:modal) do
    = render 'agreements/edit'

关于javascript，因为我现在有这个：

  - @agreements.each do |agreement|
    %tr{id: agreement.id}
      %td
        %p.agreement-discount= agreement.amount
      %td
        %p.agreement-name= agreement.name
      %td
        %p.agreement-size= agreement.total_students
      %td
        %p.agreement-size= agreement.agreement_service_students.active.size
      %td
        %a.button-assign{value: "#{agreement.id}"}
          %p.blue-text= t('service.button_assign')
      %td.table-options-icons
        - if agreement.is_assigned?
          .col-xs-12
            %p.icon-full-info-full{ title: t("message.fail_edit_destroy_agreement")}
        - else
          .col-xs-6
            %a.icon-full-pen-full.js-edit-agreement{href: "#", id: "#{agreement.id}"}
          .col-xs-6
            = link_to agreement, method: :delete, id: "agreement-destroy-#{agreement.id}",
                  data: { confirm: t('confirm_delete.agreement', agreement: agreement.name) } do
              .icon-full-trash-full.small-profile

    - content_for (:modal) do
      = render 'agreements/edit'

如果我删除了content_for标记，则模态将无法打开。

谢谢！
