How to send javascript object to php via ajax?

Question

I looked at some other questions such as this and this, but it does not me help me solve my problem. When I console-log my data, I get this:

Object["row_LM#00000010", "row_LM#00000002", "row_LM#00000009", "row_LM#00000008"]

How can I get this in php as a key value pair like row_ : LM#00000010, row_LM#00000002, row_LM#00000009,LM#00000008, so that I can loop each value? I tried JSON.stringify(), I got TypeError: cyclic object value

Here's what I have tried:

            $.ajax({
                  type:'POST',
                  url:'delinvoices.php',
                 data:{del_id:JSON.stringify(deleteInvoice)},
                success: function(data){
                     //other codes
                }
            });

The console.log of deleteInvoice gave me:

Object["row_LM#00000010", "row_LM#00000002", "row_LM#00000009", "row_LM#00000008"]

The base data comes from datatable

var deleteInvoice = dt.rows( { selected: true } ).ids();

Please help.

The best way would be to write some code and then post it in your question as an minimal reproducible example so you will get help instead of down votes — Tibrogargan

There still isn't enough information here to really help. It LOOKS like you have a simple array. Where's the base data? What does it look like? I'd be curious to see what deleteInvoice looks like BEFORE the stringify. — Rob Wood

Not really seeing what you're expecting in php. It looks like just 1 key value pair, with the key being row_ and the value being LM#00000010, row_LM#00000002, row_LM#00000009,LM#00000008 — Tibrogargan

The base data comes from datatable. var deleteInvoice = dt.rows( { selected: true } ).ids(); — Hanner

@Tibrogargan, I thought I would get the data using $_POST['del_id'] which then could be looped. — Hanner

According to this page (https://datatables.net/forums/discussion/30848/trying-to-get-get-the-row-ids-using-rows-ids), you are getting a dataTables object instance. To get an array, you'd do this:

table.rows( { selected: true } ).ids().toArray();

It might help to simplify what you're working with, the dataTables object might be what's going cyclic on you.

No problem. Thanks for giving me the points. Like 75% or more of people never bother, or I'd have 1,000 reputation points rather than under 300. =}
