                <div>请执行以下步骤以将投稿批量添加到稍后再看(可以跳过部分步骤)。执行过程中可以关闭对话框,但不能关闭页面——且将当前页面置于后台时,浏览器会暂缓甚至暂停任务执行。</div>
                <div>脚本会优先添加投稿时间较早的投稿,达到稍后再看容量上限 100 时终止执行。注意,该功能会向后台发起大量请求,滥用可能会导致一段时间内无法正常访问B站,您可以增加平均请求间隔以降低被 BAN 的概率。</div>
                <div>第一步:加载最近 <input id="gm-batch-1a" type="text" value="24"> <select id="gm-batch-1b" style="border:none;margin: 0 -4px">
                  <option value="${3600 * 24}">天</option>
                  <option value="3600" selected>小时</option>
                  <option value="60">分钟</option>
                </select> 以内发布且不存在于稍后再看的视频投稿<button id="gm-batch-1c">执行</button><button id="gm-batch-1d" disabled>终止</button></div>
                <div>第二步:缩小时间范围到 <input id="gm-batch-2a" type="text"> <select id="gm-batch-2b" style="border:none;margin: 0 -4px">
                  <option value="${3600 * 24}">天</option>

                  <option value="60">分钟</option>
                </select> 以内;可使用上下方向键(配合 Alt/Shift/Ctrl)调整数值大小<button id="gm-batch-2c" disabled>执行</button></div>
                <div>第三步:筛选 <input id="gm-batch-3a" type="text" style="width:10em">,过滤 <input id="gm-batch-3b" type="text" style="width:10em">;支持通配符 ( ? * ),使用 | 分隔关键词<button id="gm-batch-3c" disabled>执行</button></div>
                <div>第四步:将选定稿件添加到稍后再看(平均请求间隔:<input id="gm-batch-4a" type="text" value="300">ms)<button id="gm-batch-4b" disabled>执行</button><button id="gm-batch-4c" disabled>终止</button></div>
