Hi Brent, The database creation problem has been solved. I believe the reason why I can't create a new database from javascript in webpage is the security quota. It must be greater than 0. But initially, it's set as 0. So, no new database will be allowed to create.
The solution is quite similar to the approach described in the following link: http://lists.apple.com/archives/Webkitsdk-dev/2008/Apr/msg00027.html What I did is adding a line of code setQuota(origin,3000); before the check if (requirement <= quotaForOriginNoLock(origin)) return true; in the DatabaseTracker.cpp. Then, we can create the database successfully. But I am still a little bit confused about the "quota". I think 3000 is quite a big number . What does it mean? the number of databases allowed to create? or the size of space allowed for database ?
