How to check field value with custom button

Gargiucn

I created a custom editor button to check the value of a field before opening the editor.
I didn't understand the correct syntax to use to check the field.

        {
            extend: 'selectedSingle',
            text: 'selectedSingle',
            action: function (e, dt, node, config) {
                // if field value == value (for example: contratti.con_verif == 1)
                    alert("Pagamento verificato!");
                    this.close();
                }else{  
                    pagamentiEditor.edit(pagamentiTable.rows('.selected', { select: true }));
                }   
            }
        },

The example:

https://datatables.net/reference/button/selectedSingle

shows:

 console.log( dt.row( { selected: true } ).data() );

I tried with:

        {
            extend: 'selectedSingle',
            text: 'selectedSingle',
            action: function (e, dt, node, config) {
                var verificato = dt.row( { selected: true } ).data();
                if ( verificato[7] == 1 ){
                    alert("Pagamento verificato!");
                    this.close();
                }else{  
                    pagamentiEditor.edit(pagamentiTable.rows('.selected', { select: true }));
                }
            }
        },

but it's wrong (undefined)...

I solved this way:

        {
            extend: 'selectedSingle',
            text: 'selectedSingle',
            action: function (e, dt, node, config) {
                var verificato = (dt.rows( { selected: true } ).data().pluck('pagamenti').pluck('pag_verif')).join('');
                if ( verificato == 1 ){
                    alert("Pagamento verificato!");
                    this.close();
                }else{  
                    pagamentiEditor.edit(pagamentiTable.rows('.selected', { select: true }));
                }
            }
        },

I ask the experts for confirmation...
