What I am doing is saving and retrieving lot of Images on the client.
(Now indexedDB seemed to be overkill for this simple job, but since it was the only Cross-Browser solution with no limit(like localStorage), I had to use it ... and it works)
This is what my db looks like: (more specific, the only objectstore of my db)
# | key(timeID) | value
0 | 812378123 | {data:¨....¨, tnData:¨...¨, timeID:812378123}
1 | 912378123 | {data:¨....¨, tnData:¨...¨, timeID:912378123}
2 ....
KeyValue is a unique TimeID, Data contains the Image as text and tnData contains the thumbnail of this Image as text (when canvas.toBlob() is ready I will switch to that)
To retrieve a Image I just use store.get(id)
Now all of that works.
But now I just want to load the Thumbnail(¨tnData¨) - but NOT the real Image (¨data¨ which can be quite big).
So I hope there is something like store.get(id, ¨tnData¨) ...
But I did not found it, so far. Does anyone know of a easy way of doing this, without having to rework my db?
Thanks in advance ... and sorry if I am not in the right place or have broken some other rule ... first question for me ;)
