fnRender issue with 1.8

numberone

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

numberone

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?

your code is working but mine doesnt

[code]


$(document).ready(function () {
var activated = ["Inactive","Active"];
var banned = ["Active","Banned"];

$('#usertable').dataTable({
'bProcessing' : true,
'bServerSide' : true,
'sAjaxSource' : '<?php echo base_url(); ?>admin/users/getusers_byajax',
"sPaginationType": "full_numbers",
"bAutoWidth": false,
"aoColumns": [
{ "sName": "users.id", "bVisible": false },
{ "sName": "users.username" },
{ "sName": "users.email"},
{ "sName": "user_groups.group_name" },
{ "sName": "users.activated", "fnRender": function (o){ return activated[o.aData[4] ] ;} },
{ "sName": "users.banned", "fnRender": function (o){return banned[o.aData[5]] ;} },
{ "sName": "edit", "bSortable": false },
{ "sName": "delete", "bSortable": false },
],
'fnServerData': function(sSource, aoData, fnCallback)
{
$.ajax
({
'dataType': 'json',
'type' : 'POST',
'url' : sSource,
'data' : aoData,
'success' : fnCallback
});
},
});

});

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

Thanks Allan,

i added "bUseRendered": false to the columns and it worked well.

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]
