传数据给后台返回数据，最开始的办法是
重新生成一个datatable对象，但是在每次点击刷新时都会有闪动的现象，而且代价很高。理想中应该仅仅更新数据。
最后在文档中查到一个插件fnReloadAjax加入文件
$.fn.dataTableExt.oApi.fnReloadAjax = function ( oSettings, sNewSource, fnCallback, bStandingRedraw )
{
if ( sNewSource !== undefined && s NewSource !== null ) {
oSettings.sAjaxSource = sNewSource;
}
// Server-side processing should just call fnDraw
if ( oSettings.oFeatures.bServerSide ) {
this.fnDraw();
return;
}
this.oApi._fnProcessingDisplay( oSettings, true );
var that = this;
var iStart = oSettings._iDisplayStart;
var aData = [];
this.oApi._fnServerParams( oSettings, aData );
oSettings.fnServerData.call( oSettings.oInstance, oSettings.sAjaxSource, aData, function(json) {
/* Clear the old information from the table */
that.oApi._fnClearTable( oSettings );
/* Got the data - add it to the table */
var aData = (oSettings.sAjaxDataProp !== "") ?
that.oApi._fnGetObjectDataFn( oSettings.sAjaxDataProp )( json ) : json;
for ( var i=0 ; i<aData.length ; i++ )
{
that.oApi._fnAddData( oSettings, aData[i] );
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
that.fnDraw();
if ( bStandingRedraw === true )
{
oSettings._iDisplayStart = iStart;
that.oApi._fnCalculateEnd( oSettings );
that.fnDraw( false );
}
that.oApi._fnProcessingDisplay( oSettings, false );
/* Callback user function - for event handlers etc */
if ( typeof fnCallback == 'function' && fnCallback !== null )
{
fnCallback( oSettings );
}
}, oSettings );
};
使用方法
oTable.fnReloadAjax('pages/getPlayerNewData.php);
oTable.fnReloadAjax(); //使用默认
