grid中显示blob中的图片

tlkj

grid读取mysql的blob中的图片信息，根据网站中文档中写出后显示不出来  ，请帮忙看看是不是什么地方有错误

jishuang

action=blobDownloadAction

tlkj

改了以后还是那样，图片显示不出来

tlkj

  var url = biz.Request.setBizParams(require.toUrl("$UI/system/components/justep/blob/server/download.j")

1.确认控制台是否报错
2.确认关系名blobRelation设置的是否正确
3.确认主键值（rowid）blobConceptValue获取的是否正确

还有，我想问一下怎么实现对blobDownloadAction的调用的

jishuang

1.确认5楼说的值都正确吗？
2.确认数据库中是blob的数据？
3.这个案例就是调用的blobDownloadAction啊

tlkj

如何确定"&blobConceptValue=" + event.rowID      中 event.rowID是否正确
