Hi,

I have a little problem with a function. It calls him self and the var i is lost! after the call!

can anybody help me?


function change_check_all(tree_item) {
a = document.all[tree_item + "_check"];
b = document.all[tree_item + "_count"];
for(i=0;i<b.value;i++) {
if (a.value=="off") {
change_check_to(tree_item + "_" + i, 0);
} else {
change_check_to(tree_item + "_" + i, 1);
}
change_check_all(tree_item + "_" + i, i);
}
}

    Well I can help you but I'd like to give you a general tipp when writing functions:
    It is very hard to understand your source code because when you look at it the first time you can't see which subfunction is where or where it start or ends.
    [code]
    function.....
    {
    if........
    {
    do that and that
    }
    else
    {
    .........
    }

    }
    [/code]
    Also when posting a code like this some comments would help in understanding it!
