Hi,
I am drawing one data table with json data. I have two such data sets.
Initially I will be drawing table with first data set. Now clicking on link I need to populate table with another data set.
Not sure how do I do it. Can you pls help.

var aDataSet = [
["Act one ", "700", "1000","300"],
["Act two", "700", "1000","300"],
["Act three", "700", "1000","300"],
["Acct four", "700", "1000","300"]
];

var aDataSetNew = [
["Act one new ", "700", "1000","300"],
["Act two new", "700", "1000","300"],
["Act three new", "700", "1000","300"],
["Acct four new", "700", "1000","300"]
];


$('#projDataTable').dataTable( {
"aaData": aDataSet,
"sScrollY": "200px",
"sDom": 't',
"bScrollInfinite": true,
"bDeferRender": true,
"iDisplayLength": -1,
"bSort": false,
"aoColumns" : [
{ },
{ sClass: "alignRight" },
{ sClass: "alignRight" },
{ sClass: "alignRight" }
]
} );

    Use the fnClearTable and fnAddData API methods to first clear the old data and then add the new data.

    As if now I am doing it by clearing the table by
    oTable.fnClearTable();

    and the use fnAddData in a loop to add rows from another data set.
    Is there any better way to do it.

    The only reason I am asking is I have to loop through the data like below
    $.each(aDataSet1, function(i, item) {
    $('#projDataTable').dataTable().fnAddData(
    aDataSet1[i]
    );
    });

    Is this the correct way to do it. Or is there any other better way just to change dataset and update table.
    And thanks for so quick reply Allan.

    You can add 2D array of arrays - add multiple rows in a single call. Just make sure to prepare your 2D array properly, but by the looks of it you should be fine. No need for $.each()
