【中文标题】服务门户小部件表单返回“未找到记录”【英文标题】：Service Portal Widget form Returns "Record not Found" 【发布时间】：2017-05-12 17:35:23 【问题描述】：我通过克隆服务门户 (ServiceNow) 中的现有表单小部件来创建新小部件。修改了 URL (https://dev32223.service-now.com/aaportal/?id=departments&table=x_34334_aaaa_incident&sys_id=ee384830db2e32001cf8dec0cf9619de) 中的 sys_id 和表名。使用小部件创建新页面，生成的网页显示“未找到记录”

【问题讨论】：
打印所有日志信息吗？ 【参考方案1】：看起来控件没有通过var rec = $sp.getRecord(data.table, data.sys_id); 行我无法弄清楚这个问题，但我有一个替代解决方案。您可以使用 iframe（如下所示）显示表单或记录列表。
如果这回答了您的问题，请将其标记为答案。
