Hi DenesL, Massimo, thanks for your help on this, it works... Coming
from JAVA/J2EE world few months ago I didn't know I'll enjoy Python
and Web2py that much... I hope and wish this interesting experience
will benefit to someone else very soon...
Just for the info in case someone else follow this thread:
In the callback method above, instead of having
success: function(data){ alert(eval ('('+data+')')["Name"]
[0]["key1"]); }
Use the following:
success: function(data){ alert(eval(data)["Name"][0]
["key1"]); }
Otherwise you will get a JavaScript error message saying: "missing ]
after element list" this is due to the quote ' inside the eval()... So
basically just remove them.
Thanks again.
