从JsonArray

Question

检索共性与个性元素我有一个JSON在这种格式

[ 
    {"ip":"190","params":{"key":"Thread_State","value":"start"}}, 
    {"ip":"190","params":{"key":"Rate_Classification","value":"30"}}, 
    {"ip":"190","params":{"key":"Rate_Evaluation","value":"30"}}, 
    {"ip":"191","params":{"key":"Thread_State","value":"start"}}, 
    {"ip":"191","params":{"key":"Thread_State","value":"stop"}} 
] 

，我想要从基于键和值这个JSON共同和独特的元素。

例如：

共同要素是{ “IP”：190 {"key":Thread_State,"value":start}}，{ “IP”：191 {"key":Thread_State,"value":start}}

我们如何使用JavaScript这样的结果？

var dataArray = []; 
var encoded = jQuery.parseJSON(json_string); 
$.each(encoded, function (index, value) { 
    dataArray.push([value["ip"].toString(), value["params"]["key"], value["params"]["value"] ]); 
}); 
alert(dataArray);
