Next key-value pair in assosiative array

22 May 2014, 21:26

Let's assume we have

Code: Select all

array:=[1:"a",3:"b",1000:"c"]
and we have key=3. How can I go from key=3 to key=1000?

Using for-loop is not an option since this line will be called millions of times.

I could get all keys before calling this line, if needed.

Perhaps Enumerator Object could do the trick?

Until someone with more knowledge of AHK's inner workings comes along, you might try this:

Code: Select all

array:={1:"a",3:"b",1000:"c"}
linked := {}

for key in array
{
    if (A_Index > 1)
        linked[previous_key] := key
    previous_key := key
}

MsgBox % linked[3]
