jquery怎么读取这样的json数据

Question

json数据如下，pid通过传值进来，比如我传入3，现在要读出浦东机场，虹桥机场和各自的id,
这样用json怎么写呢？
var jcList = [
{"pid":"3","airport":[
{"id":"10","name":"浦东国际机场"},
{"id":"11","name":"虹桥机场"}
]},
{"pid":"1","airport":[
{"id":"12","name":"南苑机场"},
{"id":"13","name":"首都国际机场"}
]},
{"pid":"121","airport":[
{"id":"22","name":"禄口国际机场"}
]}
]

Answer 1

var objs = eval("("+jcList+")");
for(var x in obj){
   var obj = obj[x];
   if(obj.pid == 3){
      alert(obj.airport[0].name+":"+obj.airport[1].name);
   }
}

Answer 2

不好意思
var objs = eval("("+jcList+")");
for(var x in objs){//这里少了s
  var obj = objs[x];//这里也少了s
  if(obj.pid == 3){
  alert(obj.airport[0].name+":"+obj.airport[1].name);
  }
}

被你给玩了，也是我理解有错，json是字符串，你的jclist明显就是个数组嘛    <script type="text/javascript">
    var jcList = [
                    {"pid":"3","airport":[
                        {"id":"10","name":"浦东国际机场"},    
                        {"id":"11","name":"虹桥机场"}
                    ]},
                    {"pid":"1","airport":[
                        {"id":"12","name":"南苑机场"},    
                        {"id":"13","name":"首都国际机场"}
                    ]},
                    {"pid":"121","airport":[
                        {"id":"22","name":"禄口国际机场"}
                    ]}
                ];
    var objs = jcList;alert(objs)
    for(var x=0; x<objs.length; x++){
        var obj = objs[x];
        if(obj.pid == 3){
            alert(obj.airport[0].name);
        }
    }
    </script>

Answer 4

用普通的JavaScript实现了。        for (var i = 0; i < jcList.length; i++) {
            if (jcList[i].pid == '3') {
                for (var j = 0; j < jcList[i].airport.length; j++) {
                    var newOption = document.createElement("option");
                    newOption.text = jcList[i].airport[j].name;
                    newOption.value = jcList[i].airport[j].id;
                    document.getElementById('Select1').options.add(newOption);
                }
                break;
            }
        }

Answer 5

var jcList = [{"pid":"3","airport":[
    {"id":"10","name":"浦东国际机场"},    
    {"id":"11","name":"虹桥机场"}
]},{"pid":"1","airport":[
    {"id":"12","name":"南苑机场"},    
    {"id":"13","name":"首都国际机场"}
]},{"pid":"121","airport":[
    {"id":"22","name":"禄口国际机场"}
]}
];
var getAirportId=function(pid){
var rObj={},rSb=[];
$.each(jcList,function(i,o){
if(o.pid.toString()==pid.toString()){
rObj=o;return false;
}
});
$.each(rObj.airport,function(i,o){
rSb.push(o.id);
});
return rSb;
};
alert(getAirportId('3').join('\n'));
