Hi - I want to take something like ...
lstIn = []
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 10, 'LEA_AUTOID': 1000})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 11, 'LEA_AUTOID': 2000})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 11, 'LEA_AUTOID': 2001})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 11, 'LEA_AUTOID': 2003})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 12, 'LEA_AUTOID': 3000})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 12, 'LEA_AUTOID': 3001})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 12, 'LEA_AUTOID': 3002})
lstIn.append({'COM_AUTOID': 1, 'PRG_AUTOID': 12, 'LEA_AUTOID': 3003})
lstIn.append({'COM_AUTOID': 2, 'PRG_AUTOID': 110, 'LEA_AUTOID': 4000})
... and produce something like ...
sampleOut =
[[1,[10,1000]],[1,[11,[2000,2001,2003]]],[1,[12,[3000,3001,3002,3003]]],[2,[110,4000]]
Well I've now been around the block a few times with this one and I'm
still frowning !! In the process my code has become uglier and uglier -
I'm sure there must be quite an elegant way of dealing with it - could
anyone give me a push in the right direction ?
Just to provide some motivation here - I should just say that this is
cut down test case - the real problem involves creating a Javascript
structure which in turn defines a three level menu.
The resulting JS will be something like this, I think you can see how
the nested loops get into it.:
var MENU_ITEMS = [
{ pos:'relative', leveloff:[b,a], itemoff:[d,c], size:[e,f], ... },
{ ...Item 1... },
{ ...Item 2... ,
sub:[
{ ...level format... },
{ ...Item 1... },
{ ...Item 2... },
{ ...Item 3... ,
sub:[
{ ...level format... },
{ ...Item 1... },
{ ...Item 2... },
{ ...Item 3... },
{ ...Item 4... }
]
},
{ ...Item 4... },
]
},
{ ...Item 3... }
];
Interested to hear of any smart/elegant ideas.
thanks
Richard.
