輸出：

Aaberg, Jesper, 555-0100,555-0120

前端頁面接收JSON對象的執行個體：

<script>sendRecord('1');function sendRecord(record){var req = {user_id:<?php echo $userId;?>,record:record,}$.ajax({url: "/3G/wall/ajax_send_record/",type:"post",data:req,dataType:"JSON", //返回資料格式為JSON對象success: function(res){if(res.result==1){  //因為傳遞過來是JSON對象，所以不用JSON.parse()解析alert('11');}else if(res.result==2){alert('22');}else if(res.result==3){alert('33');}},error: function(){alert('error000');console.log(this);}});}</script>

<?php    function ajax_send_record()    {        $record = $_POST('record');        if ($record==1) {                    $json['result'] = 1;                    }elseif($record==2){$json['result'] = 2;}elseif(elseif($record==3){$json['result'] = 3;}$json = json_encode($json);echo $json;    }?>

將json字串用jsonnet轉成對象

根據你的json資料，可以像下面方式進行轉換：

調用Custom 類中的 DeJson方法傳入json字串返回對象

java：json字串轉化為json對象

你好！！
import java.io.*; import org.json.*; public class Demo { public static void main(String[] args) throws Exception { String str = "{\"brand_no\":\"jycy,sy\",\"unit_rank\":\"2\",\"package\":\"2\"}"; JSONObject obj = new JSONObject(str); System.out.println(obj); System.out.println(obj.get("brand_no")); // "jycy,sy" } }
