遍历json对象:
无规律:
<script>
var json = [{dd:'SB',AA:'东东',re1:123},{cccc:'dd',lk:'1qw'}];
for(var i=0,l=json.length;i<l;i++){
for(var key in json[i]){
alert(key+':'+json[i][key]);
}
}
</script>
有规律:
也可以用这个:
1、——————————————————————————————————————————————————————————————
import net.sf.json.JSONObject; String json = "{\"name\":\"lss\"}"; JSONObject jsonObj = JSONObject.fromObject(json); String name = jsonObj.getString("name"); Iterator it = jsonObj.keys(); List<String> keyListstr = new ArrayList<String>(); while(it.hasNext()){ key = (String) it.next();
value = jsonObject.getString(key); }
2、 {"info":[{"goodsId":"1234","goodsq":"10"},{"goodsId":"5678","goodsq":"20"}]}
2、———————————————————————————————————————————————————————————————
JSONObject jsonObject = new JSONObject(jsonString); JSONArray jsonArray =jsonObject.getJSONArray(“info”); for (int i = 0; i < jsonArray.length(); i++) { JSONObject jo = jsonArray.getJSONObject(i); System.out.println(jo.getString("goodsld")); System.out.println(jo.getString("goodsq")); }
