Answer 1

能弹出。

 <script type="text/javascript">
        function test(){
            var a = '[{"from":"www.baidu.com","musci":"china","type":"Classics"},{"from":"www.baidu.com","musci":"japen","type":"Country "},{"from":"www.baidu.com","musci":"Americ","type":"Hip-Hop"},{"from":"www.baidu.com","musci":"Russia","type":"Jazz"},{"from":"www.baidu.com","musci":"Korea","type":"Pop"},]';
            //alert(a);

            a= eval('('+a+')');
            for(var i = 0 ;i<a.length;i++){
                alert(a[i].from);
            }
        }
        window.onload = test;
    </script>
