Is postRemove the right event to count rows in the table?

swrobel

The removed row still seems to be present in the DOM on postRemove.

> $('#template tbody').find('tr').length
4

Code:

editor.on('postRemove', function(e, type) {
  console.log($('#template tbody').find('tr').length);
});

Output (first line is from the event handler):

4
> $('#template tbody').find('tr').length
3

If this isn't the right event, what should I be using so I can properly count the rows left in the DOM?

Also worth mentioning that we have an Editor license, just under a different account at my organization.

Hi,

Yes, at the point of the postRemove event the table has not yet been redrawn, so the row is still present (although really in a "detached" state since the next draw will remove it.

The draw is the next event that happens. The submitComplete event might be the best option here.

Allan, thanks for the reply! submitComplete works, but is there any way to listen for that event only when related to a 'remove' event? I noticed that event fires for any editor action that submits back to the server.

What you could do is:

editor.on( 'postRemove', function () {
  editor
    .off( 'submitComplete.rows' )
    .one( 'submitComplete.rows', function () {
      ...
    } );
} );

I've used off and a namespace in case you are using multiple row deletion. postRemove will execute once for each row that was removed.
