Using oTable.fnOpen inside fnDrawCallback

andreydruz

Hello,

I need to use oTable.fnOpen inside fnDrawCallback.

[code]
oTable = $(".dataTable").dataTable({
"fnDrawCallback": function (oSettings) {
oTable.fnOpen(this, "some text", 'details');
}
});
[/code]

How can I do it?

Thank's
Andrey.

You can declare another variable from within fnDrawCallback like so:

[code]
oTable = $(".dataTable").dataTable({
...
"fnDrawCallback": function () {
var nTr = \$(".dataTable tbody tr"),
checked = \$('input:radio[name=reporttype]:checked').val(),
thisTable = \$('.dataTable').dataTable(); //<----- Instead of oTable
if (checked == 'closed') {
nTr.each(function() {
if (thisTable.fnIsOpen( this )) {
thisTable.fnClose( this );
}
}
} else { // Toggle is open
nTr.each(function() {
if (!thisTable.fnIsOpen( this )) {
thisTable.fnOpen( this );
}
}
}
});
[/code]

I'm toggling all hidden rows and need to make sure I'm closed or open when the table is refreshed.

The easiest way is using the 'this' keyword - DataTables callback functions are executed with the instance's scope, so you can simply do:

[code]
oTable = $(".dataTable").dataTable({
"fnDrawCallback": function (oSettings) {
this.fnOpen(this, "some text", 'details');
}
});
[/code]
