Get json value dynamically

Question

{
 "id":["123"],
 "optionid_123":"98"
}

I have the id as a variable, but from that how can I get the optionid_*? I tried a few things, but nothing seems to work. The each is inside of the appropriate function and jsonid contains the correct value. Here is my attempt at accessing the value 98 which doesn't work:

$.each(data.id,function(){
    var jsonid = this;
    console.log( data.optionid_+jsonid ); // doesn't work
});

You can use Bracket notation:

console.log( data['optionid_' + jsonid] );
