JS 解析服务端返回的json数组

从服务器端返回的json如下：

{"idcNodeList":[
{"nodeType":0,"nodeName":"测试节点1","nodeId":"BG1f3KrE-oKI0XSQI~~~","createTime":"2015-07-21 14:39:58.000+0800","updateTime":"2015-07-21 14:39:58.000+0800","changeTime":"2015-07-21 16:01:33.000+0800","nodeStatus":1,"nodeIp":"192.168.200.75","nodePort":8099},

{"nodeType":0,"nodeName":"测试节点3","nodeId":"BGgDnlnZ7hINQiSpc~~","createTime":"2015-07-21 14:39:58.000+0800","updateTime":"2015-07-21 14:39:58.000+0800","changeTime":"2015-07-21 16:01:34.000+0800","nodeStatus":1,"nodeIp":"192.168.200.246","nodePort":9012}]}

success: function(data) {
    var obj = eval("("+data+")");
    for(var i = 0 ; i < obj["idcNodeList"].length; i++) {
        var temNodeId = escapeJquery(obj["idcNodeList"][i]["nodeId"]);
        $("#"+temNodeId).html( (obj["idcNodeList"][i]["nodeStatus"] ));
    }
}
