There is a problem loadServerData in dataAdapter

[hungdlvParticipant]

Hi All,

I am newbie jqwidget. I have a problem loadServerData in dataAdapter. This is my code:

var dataAdapter = new $.jqx.dataAdapter(dataSource, {loadServerData: function (postdata, source, callback)
	{
		$.ajax({
			url: source.url,
			data: postdata,
			type: "POST",
			async: true,
			global: false,
			success: function (data, status, xhr)
			{
				if ($.isFunction(source.beforeprocessing))
				{
					source.beforeprocessing(data, status, xhr);
				}
				var records = $.parseJSON(data);
				dataAdapter.loadjson(null, records, source);
				callback({records: dataAdapter.records, totalrecords: records[0].TotalRows});
			}
		});
	}});

My browser throw exception: “Uncaught ReferenceError: data is not defined” in jqxdata.js

Please help me,
Thanks
Hung

Hi Hung,

Why do you use API like loadjson? We do not have such in the dataAdapter’s Documentation. I would suggest you to take a look at the dataAdapter’s help topic for getting started with that plugin – http://www.jqwidgets.com/jquery-widgets-documentation/documentation/jqxdataadapter/jquery-data-adapter.htm
