net.sf.json.JSONArray 转换的Json 在非Ajax中如何转换成js对象

JSONArray arr2 = JSONArray.fromObject(compCells);
String result2 = arr2.toString();
model.addAttribute("compCells",result2.replaceAll("\"", "'"));

<input type="hidden" value="${compCells}" id="compCells">

var compCells =  $("#compCells").val();
var jsonData2 = eval( '(' + compCells + ')' );
