jQuery : How can I iterate over Java HashMap<Long,String> into Javascript?

Question

I am returning HashMap<Long,String> from server on one of the Ajax calls. How can I iterate over the it to extract key,value pair?

Thank you

Return it as JSON object:

{1:"String",5:"Foo"}

On the client, you can then access the elements then using data[1] and data[5]. While it looks like an array access, JavaScript will do the right thing (Kudos to Felix Kling for pointing that out).
