Grails controller values (map) to separate javascript file

Question

I have checked a lot of forums, but I haven't got my answer. So - I have a lot of JS code, so i keep it in separate .js file (not in .gsp view). But now I have problems of accessing controller mapped values - I need them at my JS page, so I could generate my game field (based on values, that controller gives. I have

def createGame(long id) {
 //getting my game info object...
 [gameInfo:gameInfo]      
}

And then I accessed them in view, like - ${gameInfo.playerName} etc. But how to get them to JS file? For example, player has chosen an object's color (that is JS generated). One of examples could be ball.fillStyle(${gameInfo.ballColor}) But that, of course, is not working! Thanks in advance! :)

You have to assign the values using inline JavaScript.

<script type="text/javascript">
 var gameInfo = ${gameInfo as JSON};
</script>

Yes, it will be in your GSP. Access it like your normally would. It's a JavaScript object when you do "as JSON". If you don't understand JavaScript objects, you need to do some reading.

This didn't work for me in Grails v2.3.11 - the quotes around string values were escaped even when I tried ${raw(foo as JSON)}. I ended up using this instead: var gameInfo = ${gameInfo.encodeAsJson()};. EDIT: my variable was a Map.
