DataTables ajax重新加载数据

浏览数：21 / 时间：2015年06月09日

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 );

};
