Creating a function utilising an array

[Bundy]

Hi

I am trying to create a function that adds to specific array, then
checks the array to determine whether to alert 'Yes' or 'No'.

Note this is a simplified version of the function I have created. This
function will be used with different arrays.
function change_value (check_value, array_name, array_number){

if (check_value == 'yes') {
array_name[array_number]='Y';
}
else{
delete array_name[array_number];
}

// check if there is a 'Y' anywhere in the array
if(array_name.length>0){
alert('Yes');
}
else{
alert('No');
}
return array_name;
}

Your help will be appreciated.

Regards

Bundy

What sort of help are you expecting? Since you haven't told
us what this simplified version is supposed to do or what it
is that it isn't doing that you want it to do, it's sort of
hard to know how to help.

or alert (J != array_name.length ? "aye" : "nay")

It's a good idea to read the newsgroup and its old FAQ. See below.
