jQuery not getting attribute value

Question

jQuery:

$(".close_invoice").confirm({
    title: 'Are you sure to delete it?',
    content: 'Click to Delete if you are sure else click on Close.',
    type: 'red',
    typeAnimated: true,
    buttons: {
        delete: {
            text: 'Delete',
            btnClass: 'btn-red',
            action: function() {
                alert($(this).attr("id"));
            }
        },
        close: {
            text: 'Close',
            btnClass: 'btn-blue',
            action: function() {}
        }
    }
});

HTML:

<button class="btn btn-sm green btn-outline filter-submit margin-bottom close_invoice" id="14" jc-attached="true"><i class="fa fa-times"></i> Close Invoice</button>

Anyone can please tell me Why it not taking the value of attribute ID. How can I get the value of attribute ID? It alerting undefined.

Please try to trace what "this" object is inside the action function, with console.log(this);. Because it can be a scope problem. And please tell me what ".confirm()" function is, bootbox plugin? — Tobia

this might be referencing to something else. Did you try debugging? Or can you post a snippet/fiddle? — Nisarg Shah

you give id="14" in html but in js you have to call like this alert($(this).attr("#14")); . — Mehraj Khan

You can't use this selector in function object parameters..You can save this value to a variable, then put it as function paramater object's value

I think you can use this in function obj parameter, it depends how this function parameter is called! In this case it depends on plugin function call implementation.
