Get variable name assigned to a datatable

jvcunha

It's possible get variable name assigned to a datatable ?
Example:
var tableXPTO1 = $('#myTableOne').DataTable({});
var tableXPTO2 = $('#myTableTwo').DataTable({});

$('body').on('init.dt', function (settings) {
identify variable name assigned to a datatable inside 'settings' (tableXPTO1 or tableXPTO2 ?)
}

You wouldn't be able to get the variable name. That is a Javascript object which Datatables has no knowledge of.You could do something like this to get the table ID. Or simple just get an API instance to work with the Datatable.

If this doesn't help then please explain what you want to do in the init event.

Hi Kevin,
I would like to set some common events only once for each table. Example:

$ ('body'). on ('init.dt', function (settings) {
    variablename.on ('select', function (e, dt, type, indexes) {
         code ....
    });

    variablename.on ('deselect', function (e, dt, type, indexes) {
         code ....
    });
}

No need to use:

    $ ('# tableId'). on ('deselect', function (e, dt, type, indexes) {
         code ....
    });

The table variable is already in memory

Like I said the table variables are Javascript objects. Datatables has no knowledge of the variable name used. You can do something like this example:

http://live.datatables.net/marizosi/2/edit

It cascades the events and initializes Datatables. Within the events it uses jQuery to get the table being used via $(this).
