[flexcoders] Checking if an object exists
Hello all,
I'm here for one of my questions again :P
I need to make a comparison like this
if (archive[record_id][1].deleted_id == deleted_id) {
}
My problem is that [1].deleted_id might not exist at this point.
I know that archive[record_id] exists so how can i make this
comparison above?
[1] might not exists and i can't use hasOwnProperty(1) because it
throws an error as well.
can someone help me?! :P

Re: [flexcoders] Checking if an object exists
If it's an array, then you want:
if(archive[record_id].length 1)
{
//do stuff
}

Also, you can check:
if (1 in archive[record_id])
{
//do stuff
}
