I have something like this:
function recurse(a){
for(i = a; i < 3; i++){
alert(i);
if(i == 0){
recurse(++a);
}
}
}
recurse(0);
the output that i would expect is 0 (calls the new function) 1, 2 (ends the second function called), and then finishes the first run of the function with 1 and 2. But instead it only alert 0,1 and 2 once and it finishes.
i is global
Try var i, and you may get the behavior you're expecting.
function recurse(a){
for(var i = a; i < 3; i++){
alert(i);
if(i == 0){
recurse(++a);
}
}
}
recurse(0);
outputs: 0, 1, 2, 1, 2
the first 1, 2 being from the deeper level of recursion.
As originally written, you'd get 0 from the top level, 1,2 from the deeper level, and then nothing else in the top level (because i < 3 was no longer satisfied).
