// 宣告兩個json陣列 JSONArray gResTable = new JSONArray();
JSONArray gCmtTable = new JSONArray();
// 宣告json物件
JSONObject outData = new JSONObject();
//把json陣列加到json物件中outData.put("ResTable", gResTable); outData.put("CmtTable", gCmtTable); //此時創建出來的如下:jsonData={"ResTable":[],"CmtTable":[]}; 把json資料加到json陣列中 for (int i = 0; i < 2; i ++) { JSONObject node = new JSONObject(); node.put("thumb_path", "./Image/" + i +".gif"); node.put("flash_path", "./Image/" + i +".gif"); node.put("desc1", "可疑車輛" + i); node.put("desc2", ""); node.put("desc3", ""); node.put("desc4", ""); node.put("title", "hello"); node.put("upload_time", (new java.util.Date()).toString()); node.put("uploader", "王二"); gResTable.put(node); } for (int i = 0; i < 2; i ++) { JSONObject node = new JSONObject(); node.put("logo_path", "./Image/" + i +".gif"); node.put("comment", "hello"); node.put("comment_time", (new java.util.Date()).toString()); node.put("author", "王二"); gCmtTable.put(node); } 創建出來的json格式如下：
/* jsonData={"ResTable":[ {"upload_time":"Sat May 26 20:16:37 CST 2012","title":"hello","flash_path":"./Image/0.gif","uploader":"王二","thumb_path":"./Image/0.gif","desc3":"","desc4":"","desc1":"可疑車輛0","desc2":""}, {"upload_time":"Sat May 26 20:16:37 CST 2012","title":"hello","flash_path":"./Image/1.gif","uploader":"王二","thumb_path":"./Image/1.gif","desc3":"","desc4":"","desc1":"可疑車輛1","desc2":""}], "CmtTable": [{"author":"王二","logo_path":"./Image/0.gif","comment":"hello","comment_time":"Sat May 26 20:16:37 CST 2012"}, {"author":"王二","logo_path":"./Image/1.gif","comment":"hello","comment_time":"Sat May 26 20:16:37 CST 2012"} ]}; */
