Grails控制器值(映射)以单独的javascript文件 [英] Grails controller values (map) to separate javascript file

问题描述

我检查了很多论坛，但没有得到答案. 所以-我有很多JS代码，因此我将其保存在单独的.js文件中(不在.gsp视图中). 但是现在我在访问控制器映射的值时遇到问题-我在JS页面上需要它们，因此我可以生成我的游戏字段(基于该控制器提供的值). 我有

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]      
}

然后在视图中访问它们，例如-${gameInfo.playerName}等. 但是如何将它们保存到JS文件中呢?例如，玩家选择了对象的颜色(由JS生成). 示例之一可能是ball.fillStyle(${gameInfo.ballColor}) 但是，那当然是行不通的！ 提前致谢！ :)

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! :)

推荐答案

您必须使用嵌入式JavaScript来分配值.

You have to assign the values using inline JavaScript.

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