在新闻模板扩展了一个视频上传，在前台标签怎么取值

<video src="${content.attr.videoSrc.resUrl!}" autoplay controls width="1176" height="600"></video>

不行，我不在内容页面上使用，我是在栏目所在的页面上，怎么获取

默认模板有案例，这个就是栏目的下调用视频

 [@cms_content_list count='1' channelId='${channel.id!}']
                    [#list tag_list as a]
              <div class="content-box">
                  <p class="title">${a.title!}</p>
                  <div class="txt">
                      ${a.txt!}
                  </div>
              </div>
            </div>
            <div class="right-box">
                <div class="sp-cont-left" style="margin-top:15px;width: 390px">

                    <!--                                        <img class="sp-cont-img" src="${a.iconUrl!}" alt=""/>-->
                    <video width="100%" height="250" src="${a.attr.video.resUrl!}" type="video/mp4"
                           id="player1" poster="${a.iconUrl!}"
                           controls="controls" preload="none" style="object-fit:fill"></video>
<!--                    <div class="sp-div" style="margin:10px 0px">[@text_cut s=a.title len=20 append='...' /]</div>-->
                    <!--                                        <img class="sp-bf" src="${res}/images/indexJLY/dangjian/bf.png" />-->
                </div>
            </div>
            [/#list]
            [/@cms_content_list]
我就是这么写的然后标签报错

复制我们演示站的，我们演示站有案例不可能报错的，我截图上面部分标签您核对下

那你复制给我，这个模板已经删除了
