[英]jquery datatable with ajax of json datasource
我正在嘗試使用帶有AJAX的jquery數據表從ASP.NET MVC實體框架加載數據。 數據沒有以某種方式顯示在表格中。 需要您的幫助來了解我要去哪里。
當我在瀏覽器中執行json時,它返回以下字符串
[{"Region1":"South2","RegionId":1},
{"Region1":"Ahmedabad","RegionId":2},
{"Region1":"Bangalore","RegionId":3},
{"Region1":"Bhubaneswar","RegionId":4},
{"Region1":"Bilshpur","RegionId":5}]
json的代碼是
public class RegionJSONController : ApiController
{
static azure_sociodataEntities1 ctx = new azure_sociodataEntities1();
// GET: api/RegionJSON
public dynamic Get()
{
return ctx.Regions.Include("Tags").Select(i => new { i.Region1, i.RegionId }).Take(5);
} }
html頁面是
<table id="regionsdt" class="table table-striped table-bordered table-hover">
<thead>
<tr>
<th>Region ID</th>
<th>Region</th>
</tr>
</thead>
<tbody></tbody>
</table>

$.getJSON(urlData, null, function (json) {
table = $(tableId).dataTable();
oSettings = table.fnSettings();
table.fnClearTable(this);
for (var i = 0; i < json.aaData.length; i++) {
table.oApi._fnAddData(oSettings, json.aaData[i]);
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
table.fnDraw();
});
}
function AutoReload() {
RefreshTable('#regionsdt', 'http://localhost:44379/api/RegionJSON');
setTimeout(function () { AutoReload(); }, 30000);
}
$(document).ready(function () {

我認為您發送的json對象格式錯誤。 基於https://datatables.net/examples/data_sources/ajax.html的正確格式如下:
{
"data": [
[
"south 2","1"
],
[
"Ahmedabad","2"
],
[
"Bangalore","3"
],
[
"Bhubaneswar","4"
],
[
"Bilshpur","5"
]
]
}
