Description of problem:
Hi, I am trying to delete some rows in a loop without user interaction. It is working, if I do not bypass the form and click delete for every interation.
editor.remove( this.index() ).submit();
As soon as I add the a false parameter to remove, editor is not removing the rows. I think it's the remove functions, because the submit events are not triggered as far as I can see
editor.remove(this.index(), false).submit();
The hole loop:
terminTabelle.rows().every( function ( rowIdx, tableLoop, rowLoop ) {
var data = this.data();
if ( data.ferien_id === nw.ferien_id ) {
if ( action === "edit" ) {
editor.edit(this, false)
.set(nw)
.submit();
}
if ( action === "remove" ) {
console.log(action);
console.log(this.index());
editor.remove(this.index(), false);
editor.submit();
}
}
});

The issue here is that you can have multiple actions all happening at the same time here. Editor can only have a single action active at a time, but its form submission is async.
So consider two rows to be deleted - you loop over them resulting in:
At some point in future, Editor will support that (probably in v3, whenever that happens
), but at the moment it does a single action only. So you need to wait for row 1's deletion acknowledgement first.
You can do that by providing a callback to the
submit()function, and then move on to the next row (i.e. make a queue). However, I think you'd be much better off in this case to just send a single Ajax request to delete all the rows you want to delete, and then move on to submit the request for the edit (in thesubmit()callback).So use your loop to get the id of all rows you want to delete, and trigger
remove()with that array rather than doing it one at a time. It will be a heck of a lot faster as well!Allan
Again, thank you very much Allen!
just in case someone else has a similar issue, I solved this by
