2 iterations - different results - why?

[Geoff Cox]

Hello,

Can anyone tell me why these 2 sets of code give different results?

for (J in Next) {
<action>
}
<function>
for (J=0;J<Next.len gth;++J) {
<same action as above>
}
<same function as above>

I would like to change the second version so that it gives the same
results as the first one.

Any ideas please?!

Cheers

Geoff

Joost,

OK now!

I have used the vanilla iteration and prototype.js is OK. My solution
is not very elegant I expect but it works ... I added 2 extra items to
Arry etc. The problem was not with the vanilla iteration as you
supsected but other parts of the code.

Thanks for your help.

Cheers

var Arry = [
/* State 0 : */ [1,2],
/* State 1 : */ [3],
/* State 2 : */ [3],
/* State 3 : */ [4,5],
/* State 4 : */ [6],
/* State 5 : */ [6],
/* State 6 : */ [7,8],
/* State 7 : */ [9],
/* State 8 : */ [9],
/* State 9 : */ [10,11],
/* State 10 : */ [12],
/* State 11 : */ [12] ]

var result =new Array();
var test_num=1;
function A(f)
{
soundManager.pl ay('mySound'+te st_num ,'../assets/audio-group1/Track' +
(+test_num + 22) + '.mp3');
}
function B(f)
{
result[test_num] = "same";
test_num++;
}

function C(f)
{
result[test_num] = "different" ;
test_num++;
}

function D(f) {
alert('finished ');
}

DoSpecificTask = [A, B, C, A, B, C, A, B, C, A, B, C ]

function Fn(Arg) {
var F = Arg.form, State, J, Next;
State = Arg.name.substr ing(1,3);
for (J=0 ; J<12 ; J++) F["B"+J].disabled = true; // clear all
Next = Arry[State];

for (var J = 0; J < Next.length; ++J) {
F["B"+Next[J]].disabled = false;
}
if ( (State == 10) || (State == 11) ) {
DoSpecificTask[State](F);
sendGroup1Lab5( );
} else {
//alert(State);
DoSpecificTask[State](F);
}

}
