js中遍历json

json数据：[{"toyCode":"","toyName":"name1","manufacturer_id":0,"toyType":0,"macAddr":"8C705AF44EC4","isSelected":0},{"toyCode":"","toyName":"name2","manufacturer_id":0,"toyType":0,"macAddr":"8C705AF89EC4","isSelected":0},{"toyCode":"","toyName":"name3","manufacturer_id":0,"toyType":0,"macAddr":"8C705AF90EC4","isSelected":0},{"toyCode":"","toyName":"name4","manufacturer_id":0,"toyType":0,"macAddr":"8C705AF20EC4","isSelected":0},{"toyCode":"","toyName":"name5","manufacturer_id":0,"toyType":0,"macAddr":"8C705AF09EC4","isSelected":0}]遍历var json = eval(response.string);//response.string 得到的就是顶部的json数据alert(json);for(var i=0; i<json.length; i++)    {        alert(json[i].toyName+" " + json[i].macAddr) ;   }
