How to reload the datatable(jquery) data?

How to reload the selected tab? Actually I have problem with reloading part. When I add my data I\'ll successfully saved in datatable but in id field in database it shows pr

Answer 1

You can use a simple approach...

$('YourDataTableID').dataTable()._fnAjaxUpdate();

It will refresh the data by making an ajax request with the same parameters. Very simple.

Answer 2

// Get the url from the Settings of the table: oSettings.sAjaxSource

function refreshTable(oTable) {
    table = oTable.dataTable();
    oSettings = table.fnSettings();

    //Retrieve the new data with $.getJSON. You could use it ajax too
    $.getJSON(oSettings.sAjaxSource, null, function( json ) {
        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();
    });
}

Answer 3

If anything works! Do this:

example:

<div id="tabledisplay"><table class="display" id="table"></table><table </div>

how to reload the table:

$('#tabledisplay').empty();
$('#tabledisplay').append("<table class=\"display\" id=\"table\"></table>");
initTable( "tablename");  

initTable is just a method, that initialized the Table with getJSON.

I'm posting this just in case someone need it..

Just create a button:

<button type="button" href="javascript:void(0);" onclick="mytable.fnDraw();">Refresh</button>

but don't forget to add this when calling the datatable:

mytable = $("#mytable").dataTable();

Answer 5

For the newer versions use:

var datatable = $('#table').dataTable().api();

$.get('myUrl', function(newDataArray) {
    datatable.clear();
    datatable.rows.add(newDataArray);
    datatable.draw();
});

Use the fnReloadAjax() by the DataTables.net author.

I'm copying the source code below - in case the original ever moves:

$.fn.dataTableExt.oApi.fnReloadAjax = function ( oSettings, sNewSource, fnCallback, bStandingRedraw )
{
    if ( typeof sNewSource != 'undefined' && sNewSource != null )
    {
        oSettings.sAjaxSource = sNewSource;
    }
    this.oApi._fnProcessingDisplay( oSettings, true );
    var that = this;
    var iStart = oSettings._iDisplayStart;
    var aData = [];

    this.oApi._fnServerParams( oSettings, aData );

    oSettings.fnServerData( 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 ( typeof bStandingRedraw != 'undefined' && bStandingRedraw === true )
        {
            oSettings._iDisplayStart = iStart;
            that.fnDraw( false );
        }

        that.oApi._fnProcessingDisplay( oSettings, false );

        /* Callback user function - for event handlers etc */
        if ( typeof fnCallback == 'function' && fnCallback != null )
        {
            fnCallback( oSettings );
        }
    }, oSettings );
}

/* Example call to load a new file */
oTable.fnReloadAjax( 'media/examples_support/json_source2.txt' );

/* Example call to reload from original file */
oTable.fnReloadAjax();
