47)django-以put和delete方式提交数据

#模板提交数据

        dataType: "json",
        success: function (thr) {
            if (thr.status) {
                location.reload();
            } else {
                //第二次转换JSON
                var errors = JSON.parse(thr.errors);
                //显示alert
                $(".alert").removeClass("hide");
