Question

以下是scaffold生成的代码

      # DELETE /swimming/classtimes/1
      # DELETE /swimming/classtimes/1.json
      def destroy
        @swimming_classtime = Swimming::Classtime.find(params[:id])
        @swimming_classtime.destroy

        respond_to do |format|
          format.html { redirect_to swimming_classtimes_url }
          format.json { head :no_content }
        end

  end

此html代码将发送html格式的请求

<a href="/swimming/classtimes/42" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Destroy</a>

或rails code

<%= link_to 'Destroy', swimming_classschedule, :method =>:delete, data: { confirm: 'Are you sure?' }%>

如何告诉动作返回json格式？

Answer 1

您需要指定生成的<a>标记标记返回JSON。如果您使用Rails link_to帮助程序，则可以传递data-type属性，如下所示：

<%= link_to 'Destroy', swimming_classschedule_path, :method =>:delete, data: { confirm: 'Are you sure?' }, "data-type" => "json" %>

如果您正在寻找纯HTML标记，可以使用以下内容：

<a href="/swimming/classtimes/42" data-confirm="Are you sure?" data-method="delete" rel="nofollow" data-type="json">Destroy</a>

或者，您可以简单地指出href明确检索JSON：

<a href="/swimming/classtimes/42.json" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Destroy</a>

作为一个FYI，第二个代码片段基本上是第一个代码片段的插值。
