【英文标题】：How to get some part of JSON for jQuery DataTables

【发布时间】：2015-07-31 07:36:31

【问题描述】：

我在 jQuery DataTables aaData 属性中使用 webapi，如下所示：

 "aaData": "http://api.example.com/v1/asdasd/sms/latestoutbox.json?pagesize=1000",

此请求返回一个 JSON，如下所示：

"return":
    "status":200,"message":"Accept",
"entries":
[
    "messageid":40859622,"message":"Text1","status":14,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431868680,"cost":146,
    "messageid":40859621,"message":"Text2","status":10,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431868680,"cost":146,
    "messageid":40859589,"message":"Text3","status":14,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431868620,"cost":146,
    "messageid":40858860,"message":"Text4","status":10,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431867960,"cost":146,
    "messageid":40858483,"message":"Text5","status":10,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431867600,"cost":146
]

但我只需要将“条目”的行传递给我的aaData，如下所示：

    "messageid":40859622,"message":"Text1","status":14,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431868680,"cost":146,
    "messageid":40859621,"message":"Text2","status":10,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431868680,"cost":146,
    "messageid":40859589,"message":"Text3","status":14,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431868620,"cost":146,
    "messageid":40858860,"message":"Text4","status":10,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431867960,"cost":146,
    "messageid":40858483,"message":"Text5","status":10,"statustext":"Waiting","sender":"300007575","receptor":"0911111111","date":1431867600,"cost":146

我该如何工作

"aaData": "http://api.example.com/v1/asdasd/sms/latestoutbox.json?pagesize=1000",

获取我的必要值？

【问题讨论】：

假设您将其存储在 var data = ... 中，然后是 data['entries']

我解释了我的问题，请帮助如何更改 url 以获得我的必要值？

【参考方案1】：

您需要使用sAjaxDataProp (DataTables 1.9) 或ajax.dataSrc (DataTables 1.10)，以下是手册的摘录：

默认情况下，DataTables 会在以下情况下查找属性“aaData” 从 Ajax 源获取数据或用于服务器端处理 - 此参数允许更改该属性。您可以使用 javascript点对象表示法获取多个数据源 嵌套级别。

以下是不同DataTables版本的正确初始化代码。

数据表 1.9.x

$(document).ready(function() 
  var oTable = $('#example').dataTable(
    "sAjaxSource": "http://api.example.com/v1/asdasd/sms/latestoutbox.json?pagesize=1000",
    "sAjaxDataProp": "entries"
  );
);

数据表 1.10.x

$(document).ready(function() 
  var oTable = $('#example').dataTable(
    "ajax": 
        "url": "http://api.example.com/v1/asdasd/sms/latestoutbox.json?pagesize=1000",
        "dataSrc": "entries"
    
  );
);

【参考方案2】：

function AssignResult() 

    //Call Web API
    var result =  //Get the Result
        "return":
         "status": 200, "message": "Accept" ,
        "entries":
        [
             "messageid": 40859622, "message": "Text1", "status": 14, "statustext": "Waiting", "sender": "300007575", "receptor": "0911111111", "date": 1431868680, "cost": 146 ,
             "messageid": 40859621, "message": "Text2", "status": 10, "statustext": "Waiting", "sender": "300007575", "receptor": "0911111111", "date": 1431868680, "cost": 146 ,
             "messageid": 40859589, "message": "Text3", "status": 14, "statustext": "Waiting", "sender": "300007575", "receptor": "0911111111", "date": 1431868620, "cost": 146 ,
             "messageid": 40858860, "message": "Text4", "status": 10, "statustext": "Waiting", "sender": "300007575", "receptor": "0911111111", "date": 1431867960, "cost": 146 ,
             "messageid": 40858483, "message": "Text5", "status": 10, "statustext": "Waiting", "sender": "300007575", "receptor": "0911111111", "date": 1431867600, "cost": 146 
        ]
    ;

    var aaData = result.entries; //aaData will have all the entries.

希望这会有所帮助。
