Looking for an example usage of Buttons customize

I am trying perform a selective export the with Buttons export functionality. I am hoping to use one button for exporting either ALL rows or just the selected rows if some rows are selected. The description of the customize() function appears to be what I want to use but I can't seem to get it to work. What are the parameters the function takes and how are they used to filter the data.
Perhaps just a good example of usage will get me on my way?
Shown below is how I was trying to use it but it always results in an "undefined" export data set:
buttons: [ {
extend: 'csv',
text: 'CSV',
header: true,
filename: function(){
return 'Export_' + new Date().getTime();
},
customize: function(data, config){
var count = table.rows( { selected: true } ).count();
if (count > 0){
data = table.buttons.exportData( { selected: true } );
} else {
data = table.buttons.exportData();
}
}
}]

The
customizemethod isn't what you want here - its too late by that time. I guess it could be made to work, but I think it would be a lot of work.It probably needs a little change in this function. Check to see if any rows are selected, and if so, use the
selected: truemodifier. If not, then just allow it to select all. That should probably be a toggable option (default disabled).Nice idea!

Thanks for the lightning quick response, Allan!
I'll go ahead and modify my local version of the code. Does this sound like an official feature you would be willing or looking to add in the future?

Yes - I think that would be a useful addition that others would benefit from as well.
