hi,

this is not working after the lib updated. it seems like a bug.

[code]

var activated=new Array("Inactive","Active");
.
.
{ "sName": "activated", "fnRender": function (oObj){return activated[oObj.aData[4]];} },

[/code]

it returns "undefined" . its working with 1.7.6 without problem.

Thanks.

    Interesting one. I presume oObj.aData[4] holds either '0' or '1'? Could you possibly post up an example of this problem?

    Thanks,
    Allan

    yes it holds '0' or '1'

    activated[1] works
    oObj.aData[4] this one returns 0 or 1

    but activated[oObj.aData[4]] returns undefined. :S

    i made it work by doing,

    var activated=new Array(2,3,"Inactive","Active");

    it is meaningless.im sure that something wrong with fnRender..

    it is something returns like "activated[ activated[0] ]" or "activated[ activated[1] ]"
    while using activated[oObj.aData[4]]

    thanx for help ^^

    If you add the following to your fnRender function, what comes out on the console:

    [code]
    console.log( '{'+oObj.aData[4]+'}' );
    [/code]

    var activated=new Array("Inactive","Active");



    console.log( '{'+oObj.aData[4]+'}' );
    {1}
    {_firebugIgnore}
    {0}
    {_firebugIgnore}
    {1}
    {_firebugIgnore}
    {1}
    {_firebugIgnore}
    ..

    console.log( '{'+activated[ oObj.aData[4] ]+'}' );
    {Active}
    {undefined}
    {Active}
    {undefined}
    {Inactive}
    {undefined}
    {Active}
    {undefined}
    {Active}
    {undefined}
    {Active}
    {undefined}
    {Active}
    {undefined}

    If the render function is trying to get the property _firebugIgnore from your 'activated' array, then that is what is causing the issue. However, where that request is coming from I have no idea!

    I've just tried this:

    [code]
    $(document).ready(function() {
    var a = [ "zero", "one" ];
    $('#example').dataTable( {
    "aoColumnDefs": [
    {
    "fnRender": function (o) {
    return a[ o.aData[0] ];
    },
    "aTargets": [1]
    }
    ]
    } );
    } );
    [/code]
    With this table:

    [code]



    first
    second




    0



    1



    1



    0




    [/code]
    and it seems to work absolutely fine. No errors or weird behaviour in Safari or Firefox.

    Could you post either a link to your page, or your full initialisation code please?

    I think I might know what the issue is - could you add

    [code]
    "bUseRendered": false,
    [/code]
    to your column definition for the column with the rendering function and let me know what the result is?

    I think the issue is that fnRender is being called twice with server-side processing in 1.8 (intentionally so, but this is an unintentional side effect).

    Thanks,
    Allan

    i used the above but still am not able to make it work ,

    [code]

    "aoColumnDefs": [
    { "mDataProp": "Select",
    "fnRender" : function ( oObj ) {
    console.log(oObj.aData[0]);
    console.log(oObj.aData[oObj.oSettings.aoColumns[oObj.iDataColumn].mDataProp]);
    return ' ';
    },
    "bUseRendered": false,
    "aTargets": [ 0 ]
    },
    { "mDataProp": "userName",
    "aTargets": [ 1 ] },
    { "mDataProp": "loginTime",
    "aTargets": [ 2 ] }

    "fnDrawCallback": function() {
    persistChecked();
    }

    [/code]
