After making an ajax call to a certain url I am returned data in the form of a json object of the format:

```
{"feild1":["val1","val2","val3",...,"valn"],
 "feild2":["vala","valb","valc",...,"valx"]}

```

I want to combine the values of feild1 and feild2 so that I have a single array of the type :

```
["val1","val2","val3",...,"valn","vala","valb","valc",...,"valx"]

```

So I can send this single array to the response function for autocomplete. If I send `data.feild1` and then `data.feild2` then values of `data.feild2` only show up in the drop down.
