请问为什么我的template不起作用？

后台返回的数据格式是这样的：

            }
        }
    ]
}

我的代码是这样的：

$.ajax('/application/indexhistory?appName=' + '${appName}' + '&page=' + page).done(function (data) {
                list = _(data.result).map(function (record) {
                    record.fields.addtime_display = record.fields.addtime.replace('T', ' ');
                    if(type == 'full'){
                        record.fields.version = record.fields.fullindexversion;
                    }
                    else{
                        record.fields.version = record.fields.serialid;
                    }
                    return _.template('<tr>'
                            + '<td><%= version %></td>'
                            + '<td><%= addtime_display %></td>'
                            + '<td class="text-right time-spent"><%= timespent %></td>'
                            + '<td class="text-right"><%= indexcount %></td>'
                            + '</tr>', record.fields);
                });
                $('#full-history').html('<p> aaa' + list + '</p>');
                setButtonState(data, page);
            });

不能正确的填充list，请问是什么原因？这个写法我是从一个别人的网站源码学的，不知道是不是有什么坑？

你没有看到吗，你把一个}写成了]
