js端循环多条数据存入json数组

var dataList = [];
var dataObject = "";
var row_limit = scopeView.paramsDataGrid.data.rows.length; // 查询条数
if (row_limit != 0) {
    for (var no = 1; no <= row_limit; no++) {
        var priceData = $('#price_id' + no).val();
        dataObject={
                'price' : priceData,
                'operation_id' : myApp.mTransfer.fGet(scopeView.pConst.operation_id), //前画面跳转值
                'toll_id' : scopeView.paramsDataGrid.data.rows[no-1][5]  // 当前条的字段值
    }
     dataList[no-1] = dataObject;
}

myCrud.fUpdate({
     resource : '路径'
     isIgnoreForm : true,
     data : {dataJson:JSON.stringify(dataList)},  // 转换JSON 字符串
     onCompleted : function(result) {
         scopeView.mEvaluate.MSG_2002410_FINISH.fShow();  //成功信息
         scopeView.actionClose(); // 成功后关闭画面
     },
     isAsyncBusy : true
});

后端接收的json数组：
dataJson=[{price=11, operation_id=382761932419135, toll_id=88881}, {price=33, operation_id=382761932419135, toll_id=9999}]

//json转换为map
Map<String, Object> params = this.getRequestMapJSON(request);

JSONObject line=JSONObject.fromObject(params);
JSONArray paramList=line.getJSONArray("dataJson");
遍历
for(int i=0;i<paramList.size();i++){
    toll_id = (String) paramList.getJSONObject(i).get("toll_id"); //取得json里的key值
}


public Map<String , Object> getRequestMapJSON(@Context HttpServletRequest request) {
   Map<String, Object> paramMap = super.getRequestMap(request);
   // JSONパーサー
   ObjectMapper mapper = new ObjectMapper();
   try {
       // 運行指示をJSONから配列に変換
       Object send = mapper.readValue(paramMap.get("dataJson").toString(), Object.class);
       paramMap.put("dataJson", send);
   } catch (IOException e) {
      / 変換エラーの場合は、セットしない。
   }
   return paramMap;
}
