New API methods

New API methods

In general, I'd like to say that the new API is great - though I sometimes struggle to find the new API equivalents for things I have already implemented.

Thus data() appears to be the equivalent to fnGetData(), and I am assuming that all the old functions have a new equivalent.

I currently need to update data in a hidden column (col 0), and the data changes need to be reflected for searching.
The only way I could find is to use fnUpdate(), in a clumsy mix of old & new API:

var indeces  = oTable.api().rows().indexes()

for ( var i=0; i<indeces.length; i++ )
{
    var row_data = oTable.api().row( indeces[i] ).data()

    if ( row_data[0] != new_cell_data )
      oTable.fnUpdate( new_cell_data, indeces[i], 0, false, false )
}

oTable.api().draw()

Could you suggest a cleaner soln - perhaps using new API instead of fnUpdate?

A side-effect of fnUpdate seems to be that it destroys existing event bindings on
all cells of the updated row. Is this avoidable?

What would be great is a sort of cheat - sheet, a 2 col table giving equivalents of common tasks in new & old APIs.

    Not if the event handlers are attached to the elements inside the cells, since the innerHTML is written to. You could use a delegated event on the tbody, which is what I typically do myself.

    For your code - a shorter version using the new API only would be:

    table.cells( null, 0 ).indexes().each( function ( idx ) {
      if ( table.cell( idx ).data() != new_cell_data ) {
        table.cell( idx ).data( new_cell_data );
      }
    } );

    Excellent - the cheat-sheet is great (just wish I'd found it earlier), as is the code snippet & event delegation hint.

    Thank you gentlemen.
