Handlebars 获取each外定义的属性

需要在图中显示该属性

<div class="area-bd">
                    <ul class="videoList">
                        {{#each playVideos}}
                        <li>
                            <a href="{{url}}" target="_blank" class="video">
                               <!-- <img src="{{picUrl}}" width="350" height="192">-->
                                <img src="{{picUrl}}" width="350" height="192">
                                <span class="icon"></span>
                                <i class="tit">{{title}}</i>
                            </a>
                            <div class="labels">
                                <span >{{sourceName}}  {{../productId}}</span>
                                {{#each labelNames}}
                                <a href="../info/tag{{splitHelper this ',' 2}}/{{../../productId}}_video.shtml" target="_blank">{{splitHelper this ',' 1}}</a>
                                {{/each}}
                            </div>
                        </li>
                        {{/each}}
                    </ul>

                </div>

发现个很狗血的写法

如果有一个each 遍历在外面就要用 ../,如果是外面有一层each 里面还有一层each在each里面就要../../这样子写

数据结构如下:

{
 productId: '123456',
 playVideos: [{
  title: 'xxxxxxx',
  labelNames: [Array],
 }]
}
